How many oxygen atoms are in the product H2CO3 H2O+CO2

Answers

Answer 1

The products H₂O and CO₂ from the decomposition of H₂CO₃ contain a total of 3 oxygen atoms, with one from the water and two from the carbon dioxide.

The question How many oxygen atoms are in the product H₂CO₃ H₂O+CO₂is a chemistry problem that involves counting the number of oxygen atoms in the products of a chemical reaction. The compound H₂CO₃ decomposes into H₂O (water) and CO₂ (carbon dioxide). To determine the number of oxygen atoms, we look at the products H₂O and CO₂. Water has one oxygen atom, and carbon dioxide has two oxygen atoms. Therefore, each molecule of H₂O has one oxygen, and each molecule of CO₂ has two oxygens.

We sum the number of oxygen atoms from both products: 1 oxygen from H₂O and 2 oxygens from CO₂, giving us a total of 3 oxygen atoms in the products of the reaction.

A scientist is designing an investigation to study the impact of UV radiation present in high-altitude habitats on the population of mountain yellow-legged frog. What type population is most likely to be a control group for the study?

Answers

A population of the frogs that do not receive the UV radiation would work as a good control group. In this case, since the impact of the radiation is the variable under study, a group that receives no radiation, and thereby should not exhibit a change, would be a control group that could be compared against the frogs that do receive the radiation.

Answer:

I think its either C, Mountain frogs in a lab setting exposed to UV rays from a sun lamp or D, Mountain frogs in a lab setting with no UV ray exposure

Explanation:

EDIT: I searched up meaning of control group and got this,

"A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results."

A.high power and health problems
B.noise pollution and health problems
C.efficient travel and noise pollution
D.efficient travel and high power

Answers

B, c and d are positives and a has high power a plus next to a negative, so B is the only one with two positives.

B) Noise pollution and health problems.
The internal combustion engine is behind virtually every form of high-speed travel that we have today, from early planes to cars to trains. With this advancement in technology have come some drawbacks.

2 of these drawbacks are noise pollution and health problems. Health problems are due to more pollution in the air, and less directly, higher rates of obesity due to a less active lifestyle. Noise pollution is quite obvious, these machines make loud noises that are unpleasant to listen to.

Keep in mind that although every option listed is an impact of the internal combustion engine, B is the only one that lists two negative impacts.

passive transport involves movement of substances from?

Answers

osmosis is the answer babe.

The correct answer is " passive transport involves movement of substances down their concentration gradient. This is the correct answer because passive transport requires no membrane transporter that would use ATP for energy which would be "active transport". Without the use of an ATP driven transporter, the only way molecules can travel between membranes is by going from an area of high concentration, through the passive transporter, to an area of low concentration.

Calculate the osmotic pressure of a solution containing 24.6g of glycerin in 250ml of solution at 298K

Answers

The formula to calculate osmotic pressure is
Osmotic Pressure = M R T
M = Molarity
R = Ideal Gas Constant
T = Temperature in Kelvin

So,
24.6/.2254kg=109.139g /kg >>>>> Molarity
109.139 x mols/92 g = 1.186 mols kg^-1
1.186 x 0.08134 x 298 K = 28.755 atm
1.06852 x 0.08134 x 298K= 26.5 atm

The answer is 26.5

Final answer:

The osmotic pressure of a solution containing 24.6g of glycerin in 250ml of solution at 298K is calculated using the formula for osmotic pressure and found to be 26.2 atm.

Explanation:

To calculate the osmotic pressure of a solution containing 24.6g of glycerin (C₃H₅(OH)₃) at 298K, we first need to find the molarity of the solution. Given that the molar mass of glycerin is approximately 92.09 g/mol, the moles of glycerin can be calculated as:

Moles of glycerin = 24.6 g / 92.09 g/mol = 0.267 moles

Since the solution volume is 250 mL, or 0.25 L, the molarity (M) of the solution is:

M = Moles of solute / Volume of solution (L) = 0.267 moles / 0.25 L = 1.068 M

The formula to calculate osmotic pressure (Π) is Π = iMRT, where:

i is the van't Hoff factor (For glycerin, i = 1 because it doesn’t dissociate in solution).

M is the molarity of the solution.

R is the ideal gas constant (0.0821 L.atm/mol.K).

T is the temperature in Kelvin.

Substituting the values into the formula gives:

Π = (1)(1.068 M)(0.0821 L.atm/mol.K)(298 K) = 26.2 atm

Therefore, the osmotic pressure of the solution is 26.2 atm.

In a chemical interaction 10 g of hydrogen chloride is added to 20 g of zinc to form 24 g of zinc chloride and a certain amount of hydrogen gas. What mass of hydrogen gas is expected to be formed? 6 g ,14 g ,34 g ,54 g

Answers

6g of hydrogen gas is my answer. I'm sorry if I'm wrong.

According to mass conservation law, the total mass of reactants that is 20 + 10 = 30g is equal to the total mass in the product side. 24 g of Zinc chloride is formed then to obtain a total mass of 30g 6 g of hydrogen gas is expected to be formed.

What is law of conservation of mass?

Law of conservation of mass states that the mass is neither created nor destroyed. Thus total mass of the system is conserved. This law is thus similar to the law of conservation of energy.

According to this law the total mass in a reaction system also conserved which means the total mass of products formed will be equal to the total mass of reactants.

In the given chemical reaction, hydrogen chloride is 10 g and zinc is 20g, thus a total of 30 g is contained by the reactant side. The mass of zinc chloride formed is 24 g. One more product is formed there, i.e., hydrogen gas.

Thus total mass of zinc chloride and hydrogen gas is expected to be total mass of reactant side i.e.,30g Hence, mass of hydrogen expected to be formed is 30-24 g = 6 g.

Co2(s). Co2 Solid Solids have definite shape and definite volume. This is because the particles that build up a solid are crammed in a fixed, closely packed geometric arrangement.
Fluids (gases or liquids) do not have definite shape and occupies the shape of the containers. While gases assume the volume of the container, liquids occupy part of it.In aqueous solutions, the particles lose their shape and volume and occupies the shape of its solvent (water). The volume is also modified accordingly. CO2(s) has definite shape and definite volume. and the correct answer would be Co2 solid.

Carbon tetrachloride or CCl₄ is a covalent compound formed by the combination of four chlorine atoms with a carbon atom through sharing of electrons each other.

Carbon is 6th element with 6 electrons out of which 4 are valence electrons participating in chemical bonding. It shares these 4 electrons with other atoms and by sharing 4 electrons from other element to carbon make them stable.

Cl is 17th element with 7 valence electrons. Thus, it need one more electron to achieve octet. Therefore, it shares its one electrons with carbon and one electron from carbon in turn shares to chlorine make Cl stable. Each 4 chlorines shares one electron to carbon make 8 electrons around carbon and make it stable.

Answers

The law of conservation of mass applies to both cases, the following will explain how:

1. When 50 g of sugar undergoes a physical change, say for example dissolving or melting, the amount of sugar in the solution or melted form will also be 50 grams. This shows that the mass before and after the change was the same, in accordance to the law of conservation of mass.

2. When the magnesium strip is burned, this is a chemical reaction. The problem is that we only measure the mass of one of the substances involved in the reaction, the magnesium strip, which makes it seem like the mass has increased. Actually, during burning, the magnesium combines with oxygen in the air. This oxygen was present before the reaction, we just did not measure it.

A strong acid, HA, is added to water. Which statement about the solution is true?

It contains mostly hydroxide ions.

It contains almost no hydronium ions.

It contains little or no HA.

It contains a low amount of ions.

Answers

Answer:

The correct answer is:It contains little or no HA.

Explanation:

When a strong acid is added to water it dissociates into its constituent ion .

[tex]HA+H_2O\rightarrow H_3O^++A^-[/tex]

Actually the concentration of [tex]H^+[/tex] ions in water increases in comparison to hydroxide ions. And very little amount of HA will remain present associated in the solution.

A strong acid, HA, is added to water.The correct statement about solutions is: C. It contains little or no HA.

When a strong acid, HA, is added to water, it dissociates almost completely into hydronium ions (H₃O⁺) and its conjugate base (A⁻), leaving little or no undissociated HA.

Therefore, the solution primarily contains ions rather than the original acid molecules.When a strong acid, HA, is added to water, it ionizes almost completely. This means the acid dissociates fully into its ions, producing a high concentration of hydronium ions (H₃O⁺) and the conjugate base (A-). Therefore, the correct statement about the solution is: C. It contains little or no HA.A strong acid, by definition, yields nearly 100% of its hydrogen ions to water.

This leads to a solution with a high concentration of H₃O⁺ ions and almost no undissociated HA molecules.

Correct question is: A strong acid, HA, is added to water. Which statement about the solution is true?
