Answer:
1) acid + base = salt + water its neutralization reaction
2)A solution that is neither acidic nor basic is neutral and has a pH of 7. The pH scale, which ranges from 0 to 14, indicates how acidic or basic a substance is. A substance that has a pH below 7 is and acid and a substance with a pH above 7 is a base.
3)Self raising flour rises due to the baking powder inside.
Self raising flour is different from normal flour as it has baking powder mixed inside already. Baking powder is usually made up of a chemical called sodium carbonate, when mixed with water this will releases the gas carbon dioxide. So when you mix a cake together and pour it into a tin, the heat plus the water in the mixture will cause the baking powder to release small amounts of carbon dioxide which produces bubbles. These bubbles try to rise up and so the mixture starts to rise with all the tiny bubbles. The reason the air does not escape is because the heat from the oven is making the cake solid. Once is it solid the carbon dioxide slowly leaves the bread or cake, so don’t worry you’re not eating loads of carbon dioxide
4) They react/break down organic chemicals like oil/grease without attacking the metals that they are attached too which is better than acids which do react with metals as well
5) it is because when you vomit due to acidity in stomach
the harsh acid creates a burning sensation in the back of your throat and chest, and can also give you a sour or bitter taste in your throat and mouth

What is Mitosis (no plagiarism)
a sort of cell division that outcomes in two girl cells each having indistinguishable number and sort of chromosomes from the parent core, average of conventional tissue development.
Answer:
Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Mitosis is also the basis for healing wounds and fighting off invading pathogens that cause sickness. Certain organisms lose millions of cells per day as part of their normal function. Mitosis allows old cells to be replaced by new ones, ensuring an army of fully functioning cells.

A helium filled balloon has a volume of 2.48L and a pressure of 150kpa the volume of the balloon increases to 2.98L what is the new pressure of the helium gas
Answer:
THE NEW PRESSURE OF THE HELIUM GAS IS 124kPa AFTER THE VOLUME WAS INCREASED FROM 2.48 L TO 2.98 L
Explanation:
Using Boyle's law which states that at constant temperature, the pressure of a given gas is inversely proportional to the volume occupied by the gas.
Mathematically,
P1 V1 = P2 V2
P1 = 150 kPa = 150 * 10^3 Pa
V1 = 2.48 L
V2 = 2.98 L
P2 = ?
Rearranging the formula making P2 the subject of the equation, we obtain;
P2 = P1 V1 / V2
P2 = 150 * 10^3 * 2.48 / 2.98
P2 = 372 * 10 ^3 / 2.98
P2 = 124.83 * 10^3 Pa or 124.8kPa
In other words, the new pressure of the helium gas after its volume was increased from 2.48 L to 2.98 L is 124.8kPa.

Determine the empirical formula of a compound that is 39.99% carbon, 53.28% Oxygen and 6.73% Hydrogen
Answer:
CH2O
Explanation:
Pretend you have a 100 gram sample.
39.99 g C * (1 mol/12.01 g) = 3.33 moles C
53.28 g O * (1 mol/16 g) = 3.33 moles O
6.73 g H * (1 mol/ 1.008 g) = 6.676 moles H
You can see from this data that there are double the number of moles of H compared to the moles of C and O.
To find the empirical formula, you divide all the moles by the least number of moles. In this case, the least number of moles is 3.33. So for carbon and oxygen, divide 3.33 by 3.33... this equals 1. For H, divide 6.676 by 3.33... this is about equal to 2. Therefore, the empirical formula is CH2O. :)

Calculate the heat needed to increase the temperature of 100. g water from 45.7 C to 103.5 C.
ΔHvaporization= 2260 J/g
Ch2o=1.90 J/g (gas)
Ch2o=4.18 J/g C (liquid)
Answer:
Total heat required to raise the temperature of water from 45.7°C to 103.5°C
= 249,362.4 J
Explanation:
The Heat required to raise the temperature of 100.0 g of water from 45.7°C to 103.5°C will be a sum of;
- The heat required to raise the 100 g of water from 45.7°C to water's boiling point of 100°C
- The Heat required to vaporize the 100 g of water at its boiling point
- The Heat required to raise the temperature of this vapour from 100°C to 103.5°C
1) The heat required to raise the 100 g of water from 45.7°C to water's boiling point of 100°C
Q = mCΔT
m = 100 g
C = 4.18 J/g.°C
ΔT = change in temperature = (100 - 45.7) = 54.3°C
Q = 100 × 4.18 × 54.3 = 22,697.4 J
2) The Heat required to vaporize the 100 g of water at its boiling point
Q = mL
m = 100 g
L = ΔHvaporization = 2260 J/g
Q = mL = 100 × 2260 = 226,000 J
3) The Heat required to raise the temperature of this vapour from 100°C to 103.5°C
Q = mCΔT
m = 100 g
C = 1.90 J/g.°C
ΔT = change in temperature = (103.5 - 100) = 3.5°C
Q = 100 × 1.9 × 3.5 = 665 J
Total heat required to raise the temperature of water from 45.7°C to 103.5°C
= 22,697.4 + 226,000 + 665
= 249,362.4 J
Hope this Helps!!!
Answer:
249362.4 J
Explanation:
The following were Data were obtained from the question:
Mass (M) = 100g
Initial temperature (T1) = 45.7°C
Final temperature (T2) = 103.5°C
Heat of vaporisation (ΔHv) = 2260 J/g
Specific heat capacity (C) of steam = 1.90 J/g
Specific heat capacity (C) of water = 4.18 J/g
To calculate the heat needed to increase the temperature of water from 45.7°C to 103.5°C, the following must be observed:
Step 1:
Determination of the heat needed to raise the temperature of water from
45.7°C to its boiling point 100°C.
This is illustrated below:
Mass (M) = 100g
Initial temperature (T1) = 45.7°C
Final temperature (T2) = 100°C
Specific heat capacity (C) of water = 4.18 J/g
Change in temperature (ΔT) = T2 – T1 = 100°C – 45.7°C = 54.3°C
Heat (Q1) =?
Q = MCΔT
Q1 = 100 x 4.18 x 54.3
Q1 = 22697.4 J
Step 2:
Determination of the heat needed to vaporise 100g of water.
This is illustrated below:
Mass (M) = 100g
Heat of vaporisation (ΔHv) = 2260 J/g
Heat (Q2) =?
Q2 = MΔHv
Q2 = 100 x 2260
Q2 = 226000 J
Step 3:
Determination of the heat needed to raise the temperature of steam from 100°C to 103.5°C.
This is illustrated below:
Mass (M) = 100g
Initial temperature (T1) = 100°C
Final temperature (T2) = 103.5°C
Specific heat capacity (C) of steam = 1.90 J/g
Change in temperature (ΔT) = T2 – T1 = 103.5°C – 100°C = 3.5°C
Heat (Q3) =?
Q3 = MCΔT
Q3 = 100 x 1.9 x 3.5
Q3 = 665 J
Step 4:
Determination of the overall heat needed.
This is simply obtained by adding all the heat calculated above. This is illustrated:
QT = Q1 + Q2 + Q3
Q1 = 22697.4 J
Q2 = 226000 J
Q3 = 665 J
Total heat (QT) =..?
QT = Q1 + Q2 + Q3
QT = 22697.4 + 226000 + 665
QT = 249362.4 J
Therefore, the heat needed to increase the temperature of 100g of water from 45.7°C to 103.5°C is 249362.4 J

A sample of gas starts at 1.00 atm, 0.00 degrees Celsius, and 30.0 mL. What is the volume if the temperature increases to 27.0 degrees Celsius and the pressure increases to 2 atm?
Answer:
16.48mL
Explanation:
The following data were obtained from the question:
Initial pressure (P1) = 1 atm
Initial temperature (T1) = 0°C = 0°C + 273 = 273K
Initial volume (V1) = 30mL
Final temperature (T2) = 27°C = 27°C + 273 = 300K
Final pressure (P2) = 2atm
Final volume (V2) =..?
Applying the general gas equation, the final volume of the gas can be obtained as follow:
P1V1/T1 = P2V2/T2
1 x 30/273 = 2 x V2/300
Cross multiply to express in linear form
273 x 2 x V2 = 30 x 300
Divide both side by 273 x 2
V2 = (30 x 300)/(273 x 2)
V2 = 16.48mL
Therefore, the new volume of the gas is 16.48mL
The volume of a sample of gas that starts at 1.00 atm, 0.00 degrees celsius, and 30.0 mL is 16.48mL. Details about volume can be found below..
How to calculate volume?The volume of an ideal gas can be calculated by using the following formula:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressureP2 = final pressureT1 = initial temperatureV1 = initial volumeV2 = final volumeT2 = final temperature1 × 30/273 = 2 × V2/300
0.109 = 2V2/300
32.97 = 2V2
V2 = 16.48mL
Therefore, the volume of a sample of gas that starts at 1.00 atm, 0.00 degrees celsius, and 30.0 mL is 16.48mL.

Using general tendencies and the chart given in the introduction, predict the most likely mode of decay of each of the following radioactive isotopes.
Drag the appropriate items to their respective bins.
Note: Based on the valley of stability, the following processes generally tend to produce more stable neutron-to-proton (n/p) ratios:
Nuclei with Z≥84 tend to undergo α emission.
Nuclei with high n/p ratios undergo β ( 0−1e) emission.
Heavy nuclei with low n/p ratios are more likely to undergo electron ( 0−1e) capture.
Light nuclei with low n/p ratios are more likely to undergo positron (01e) emission.
The classification "high" or "low" n/p ratio can be determined by finding the coordinates on the graph that correspond to the number of protons (x or horizontal value) and neutrons (y or vertical value) in a given isotope. Then, observe whether this set of coordinates is above, within, or below the stability valley.

K: 19 28 4
Hg: 80 110 2
Th: 90 142 1
Na: 11 9 5

Answer:
K-47 undergoes beta decay
Hg-190 undergoes electron capture or alpha decay
Th-232 undergoes alpha decay
Na-20 undergoes positron emission
I-137 undergoes beta decay
Explanation:
Stability of a nucleus is decided by the neutron /proton (n/p) ratio. For lower elements of atomic number 1-20, n/p=1. Elements with higher atomic numbers tend to have a slight excess of neutrons to reduce the repulsive forces between the protons.
Beta emission decreases the n/p ratio, positron emission increases the n/p ratio, electron capture increases the n/p ratio and alpha decay increases the n/p ratio.
Note that a nucleus may undergo several decay processes before stable nucleus (nuclei) is/are formed.
The decay mode of radioactive isotopes is primarily determined by the atomic number (Z) and the neutron-proton (n/p) ratio. For example, K-47 and Hg-190, with high n/p ratios, would decay through β emission. Th-232, having Z≥84 and a high n/p ratio would undergo α emission. Na-20, being a light nucleus with a low n/p ratio would do positron emission, and I-137 with high n/p ratio would do β emission.
Explanation:Based on our understanding of nuclear stability and decay, radioactive isotopes decay in a way that brings them closer to a state of stability. They do this by adjusting their neutron to proton ratios (n/p) through various forms of decay. The mode of decay depends largely on the Z number (atomic number) and the n/p ratio.
K-47 (19 protons, 28 neutrons) has a high n/p ratio, thus it will likely undergo β ( 0−1e) emission.Hg-190 (80 protons, 110 neutrons) also has a high n/p ratio and is likely to decay through β ( 0−1e) emission. Th-232 (90 protons, 142 neutrons), with Z≥84 and a high n/p ratio, is most likely to undergo α emission. Na-20 (11 protons, 9 neutrons) is a light nuclei with a low n/p ratio, so it will most likely undergo positron (01e) emission. I-137 (53 protons, 84 neutrons) has a relatively high n/p ratio and would therefore most likely undergo β ( 0−1e) emission.Learn more about Radioactive Decay here:

c. a 0.4 M solution containing 290 g of aluminum nitrate (Al(NO₃)₃)
Answer:
b. L ≈ 4.00 litres
c. L ≈ 3.4 litres
Explanation:
Molarity is the number of moles of solute per litre of solution. Together a solute and a solvent makes a solution. The formula for molarity can be represented below
M = number of moles of the solute(mol)/L
where
M = molarity
mol = number of moles of the solute
L = litre of the solution.
Therefore ,
The volume of each solution can be computed below
b. a 0.5 M solution containing 250 g of manganese (II) chloride (MnCl₂)
M = number of moles of the solute(mol)/L
number of moles of MnCl₂ = mass/molar mass
molar mass of MnCl₂ = 55 + 71 = 126 g/mol
number of moles of MnCl₂ = 250/126
number of moles of MnCl₂ = 1.9841 moles
0.5 = 1.9841/L
cross multiply
0.5L = 1.9841
L = 1.9841/0.5
L = 3.97
L ≈ 4.00 litres
c. a 0.4 M solution containing 290 g of aluminum nitrate Al(NO₃)₃
M = number of moles of the solute(mol)/L
number of moles = mass/molar mass
molar mass of Al(NO₃)₃ = 27 + 14 × 3 + 48 × 3 = 27 + 42 + 144 = 213
number of moles = 290/213 = 1.3615 moles
M = number of moles of the solute(mol)/L
0.4 = 1.3615/L
cross multiply
0.4L = 1.3615
divide both sides by 0.4
L = 1.3615/0.4
L = 3.4 litres

Describe how molarity can be used in stoichiometry calculations
Answer:
The stoichiometric coefficients in your balanced chemical equation can represent molecules or moles or molarity.
When you balance an equation, you can use the coefficients to determine the quantity of either products or reactants. If the reaction occurs in water, then you can either do the conversion from reactants to products using moles or molarity.
Explanation:
For example, if you have a 1.5M solution of H2SO4, then the concentration of SO4-2 in solution can be determined by the balanced dissociation equation H2SO4 = 2H+ + SO4-2.
1.5M H2SO4(1M SO4-2/1M H2SO4) = 1.5 M SO4-2
Final answer:
Molarity is a key conversion factor in stoichiometry that relates the amount of a solute in moles to the volume of solution, facilitating calculations involving solution concentrations and chemical reactions.
Explanation:
Molarity can be used in stoichiometry calculations to determine quantities in chemical reactions. When dealing with stoichiometry problems involving solutions, molarity serves as a direct conversion factor because it is based on the mole unit. For instance, consider the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH):
HCl(aq) + NaOH(s) → H₂O(l) + NaCl(aq)
Convert the mass of NaOH to moles using its molar mass.Use the balanced chemical equation to find the molar ratio between NaOH and HCl.Convert the moles of NaOH to moles of HCl using this ratio.Finally, use the molarity of the HCl solution (moles per liter) to find the volume of HCl needed to react with the given amount of NaOH.To find out how many liters of aqueous HCl will react with a given mass of NaOH, we perform the following steps:
Note that the molarity acts as a bridge between the amount of solute (HCl) and the volume of the solution.
