Nitrogen gas (112 g) reacts with hydrogen gas to produce 40.8 g of ammonia according to the following
equation:
N2 + 3 H2 → 2 NH3
Calculate the percent yield of ammonia.
Answer:
%yield of NH₃ = 30%
Explanation:
Actual yield of NH₃ = 40.8g
Theoretical yield = ?
Equation of reaction
N₂ + 3H₂ → 2NH₃
Molar mass of NH₃ = 17g/mol
Molarmass of N = 14.00
2 molecules of N = 2 * 14.00 = 28g/mol
Number of moles = mass / molar mass
Mass = number of moles * molar mass
Mass = 1 * 28.00 = 28g of N₂ (the number of moles of N₂ from the equation is 1).
From the equation of reaction,
28g of N₂ produce (2 * 17)g of NH₃
28g of N₂ = 34g of NH₃
112g of N₂ = x g of NH₃
X = (112 * 34) / 28
X = 136g of NH₃
Theoretical yield = 136g of NH₃
% yield = (actual yield / theoretical yield) * 100
% yield = (40.8 / 136) * 100
% yield = 0.3 * 100
% yield = 30%
What is the molarity of a sodium hydroxide solution if 24 mL of the solution

MaVa = MbVb)
•0.10M
•0.25M
•0.50M
•0.75M
Answer:
Option 3. 0.50M
Explanation:
Step 1 :
We'll begin by writing the balanced equation for the reaction. This is given below:
2NaOH + H2SO4 —> Na2SO4 + 2H2O
From the above equation, we obtained the following:
Mole ratio of the acid (nA) = 1
Mole ratio of the base (nB) = 2
Step 2:
Data obtained from the question. This includes the following:
Molarity of base (Mb) =?
Volume of base (Vb) = 24 mL
Volume of acid (Va) = 12 mL
Molarity of acid (Ma) = 0.50M
Step 3:
Determination of the molarity of the base.
The molarity of the base can be obtained by applying the following equation:
MaVa/MbVb = nA/nB
0.5 x 12/Mb x 24 = 1/2
Cross multiply to express in linear form
Mb x 24 = 0.5 x 12 x 2
Divide both side by 24
Mb = (0.5 x 12 x 2) /24
Mb = 0.5 M
Therefore, the molarity of NaOH is 0.5 M

Data obtained from the question. This includes the following:
Mass of solution = 0.35kg
Molality = 0.238 m
Mass of NaCl =..?
Step 2:
Determination of the number of mole of NaCl in the solution.
Molality of a solution is simply defined as the mole of solute per unit kg of the solvent. It is given as:
Molality = mol of solute /mass of solvent (kg)
With the above formula, we calculate the mole of NaCl present in the solution as follow:
Molality = mol of solute /mass of solvent (kg)
0.238 = mol of NaCl /0.35
Cross multiply
mol of NaCl = 0.238 x 0.35
mol of NaCl = 0.0833 mol
Step 3:
Determination of the mass of NaCl in 0.0833 mol of NaCl.
This is illustrated below:
Number of mole NaCl = 0.0833 mol
Molar Mass of NaCl = 23 + 35.5 = 58.5g/mol
Mass of NaCl =..?
Mass = number of mole x molar Mass
Mass of NaCl = 0.0833 x 58.5
Mass of NaCl = 4.87g
Therefore, 4.87g of NaCl is contained in the solution.

Explain why floods, hurricanes, and tornadoes are aspects of weather, not climate.
Answer:
Floods, hurricanes, and tornadoes are all aspects of weather and not climate because climate is more related to temperature. The definition of climate is "the weather conditions prevailing in an area in general or over a long period." Floods, hurricanes, and tornadoes are not aspects of climate, they are aspects of weather.
Explanation:
Floods, hurricanes, and tornadoes are considered weather events due to their immediate and short-term nature, while climate refers to the long-term average weather patterns in a region. Weather involves day-to-day atmospheric conditions, leading to various forms of severe weather, whereas climate encompasses the general weather trends and conditions over a prolonged period.
Floods, hurricanes, and tornadoes are categorized as aspects of weather rather than climate due to their short-term occurrence and direct impact on specific regions over a brief period. Weather involves immediate atmospheric conditions, such as precipitation, wind speeds, and temperature, which can lead to the development of these extreme weather events. In contrast, climate describes the average weather conditions in a particular area over a long period, typically years or decades, encompassing patterns and trends rather than individual or short-term events. For instance, the differential heating of the Earth's surface by the Sun, which significantly influences weather patterns, can lead to the formation of severe weather phenomena like tornadoes, characterized by their funnel-shaped clouds and powerful winds, and hurricanes, known for their high winds and heavy rains forming over warm ocean waters.
The distinction between weather and climate is crucial for understanding how external forces like the Sun's heating influence Earth's atmospheric conditions, leading to immediate weather conditions and longer-term climatic trends. While floods, hurricanes, and tornadoes manifest as a result of these conditions, representing the variability and extremity of weather, climate refers to the broader, more consistent patterns that define a region's average atmospheric conditions over time.

Using your knowledge of wave characteristics and energy conversions, explain how musicians create, record, store, and replay analog sounds.
Answer:
In creating music, sound waves from the singer in the form of vibrational energy strikes and is converted into electrical signals in the microphone.
These electrical signals are converted to a magnetic field and then stored on an analogue recorder in the form of magnetic domains.
When the song is replayed, these magnetic domains create a changing magnetic field which produces electrical signal.
The electrical signal is sent to the voice coil in the speaker, where it is converted to a magnetic field.
The changing magnetic field pulls and push on the diaphragm which sets the air around it into vibration.
This vibration becomes sound wave that strikes our ears when we listen to these sounds.
The half-life of Cs-137 is 30.2 years. If the initial mass of the sample is 5.00 kg, how much will remain after 90.6 years?
Answer:
0.625 kg
Explanation:
Since 90.6 is 3 half-lives from 30.2 (90.6/30.2 = 3) , divide the initial mass of the sample by 2, and divide that quotient by 2, and divide THAT quotient by 2 to determine how much remains after 3 half-lives.
The mass will remain at 1.6 kg.
How to find the mass after 90.6 years?Mass after t years:
The mass of the elements after t years is given by the following equation:
M(t) = M(0)(1-r)[tex]^{t}[/tex]
The half-life of Cs-137 is 30.2 years.
This means that:
M (30.2) = 0.5 M (0)
M (t) = M (0)(0.9773)[tex]^{t}[/tex]
If the initial mass of the sample is 5 kg, how much will remain after 90.6 years?This is M(151), with M(0) = 100.
Then,
M(90.6) = 5(0.9773)[tex]^{90.6}[/tex]
= 5*0.24
= 1.2 kg

What is the rate of a reaction if the values are
k=0.1
a=1 M
b=2 M
rate=k(a)^2(b)^2
Answer:
Explanation:
Hi there,
To get started, let's first observe our rate law:
[tex]R=k[A]^2[B]^2[/tex] we typically use square brackets [x] for chemistry kinetics, because they specifically tell us we are dealing with concentrations.
This rate law is in fourth-order, because the concentrations powers add up to 4. We are not told the unit of time for this prompt (unless you know it), so I just assumed the time unit to be "time."
To calculate the reaction rate, we simply plug in the concentration of A and B into the rate law. k is the rate constant and stays the same for an individual reaction.
[tex]R=(0.1 \ M^{-3}*time^{-1})[1 \ M]^2[2 \ M]^2=0.4 \ M/time[/tex]
Thus, the rate of reaction with those concentrations is 0.4 M/time.
Notice, the rate constant does in fact have units of it own. The unit for k can be calculated by knowing that:
Rate (R) must end up with units of concentration (M) per time. The concentrations raised to a power can be used to help solve for the units of k.If you liked this solution, leave it as Brainliest Answer and give a Rating!
The rate of reaction with those concentrations is 0.4 M/time.
What is the rate of a reaction?The reaction rate is said to be the decrease in the concentration of the reactant or the increase in the concentration of the product per unit of time. Reaction rate measures how fast the reactant is used up or how fast the product is formed.
For a given reaction like
[tex]Mg(s) + O_2(g)[/tex] → [tex]2MgO(aq)[/tex]
The reaction rate is derived by measuring how fast the concentration of Mg and [tex]O_2[/tex] decreases or how fast the concentration of MgO increases. Mathematically reaction rate can be expressed as
Reaction rate = Δconcentration/ ΔTime
Rate=[tex]k(a)^2(b)^2[/tex] We typically use square brackets [x] for chemistry kinetics, because they specifically tell us we are dealing with concentrations.
This rate law is in fourth-order because the concentration powers add up to 4. We are not told the unit of time for this prompt (unless you know it), so I just assumed the time unit to be "time."

Answer:
The correct answer is option A, that is, mitosis only has one cell division set.
Explanation:
The two kinds of nuclear division that takes place at the time of cell differentiation are meiosis and mitosis. In the process of mitosis, the cells of the body get divide, while in meiosis the sex cells are differentiated.
While going through the process of mitosis, the cell divides only one time, on the other hand, during meiosis a cell divides two times. After going through mitosis production of two diploid daughter cells takes place, while after going through meiosis generation of four haploid daughter cells takes place. Thus, it is clear from the diagram that the process of meiosis is taking place, as the formation of four haploid cells is taking place as the cell is dividing two times.
All living organisms are part of their environment which is composed of biotic and abiotic factors that interact with each other. The interaction of living organisms with its environment are vital to the organisms survial. What is this interaction called?
Answer:
Ecology
Explanation:
Final answer:
The term for the interaction between living organisms and their environment, involving biotic and abiotic factors, is ecology. An ecosystem is the result of this interaction, including processes like respiration and photosynthesis that exemplify the interdependence of biotic and abiotic components.
Explanation:
The interaction between living organisms and their environment, which includes both biotic and abiotic factors, is a fundamental aspect of biology and is referred to as ecology. Biotic factors are the living parts of the environment, while abiotic factors include the nonliving components such as temperature, water, soil, and air. The complex system formed by the interplay of these factors is known as an ecosystem. Within an ecosystem, living organisms carry out processes like respiration and photosynthesis that influence the abiotic conditions, while the physical processes in the environment can affect the behavior and the very existence of living organisms.
For example, plants, as biotic factors, require abiotic components like sunlight, water, and carbon dioxide to perform photosynthesis. This process not only enables plants to produce their own food but also contributes oxygen to the environment, benefiting other organisms. Another interaction would be animals breathing in oxygen (an abiotic factor) and exhaling carbon dioxide, which is then used by plants. These exchanges illustrate the interdependence of biotic and abiotic factors and the cyclical nature of ecosystem function.

What is the molarity of a sodium hydroxide solution made by combining 2.0 L of 0.60 M NaOH with 495 mL of 3.0 M NaOH?
Assume the volumes of the two solutions to be additive.
Answer:
1.1 M
Explanation:
I git it wrong and it gave me the answer
The molarity of the final solution i.e. sodium hydroxide solution at the time of combining should be 1.1.
Calculation of the molarity:Since
Molarity (M1) = 0.60 M
Volume ( V1) = 2.0 L
Molarity ( M2 ) = 3.0 M
Volume ( V2) = 495 ml = 0.495 L
We know that
Moles = Molarity * volume in L
Now
Moles of 1st solution = n1 = M1 * V1
So
n1 = 0.60 * 2.0 = 1.2 mol
Now
Moles of 2nd solution = n2 = M2 * V2
So, n2 = 3 * 0.495 = 1.485 mol
Now
Total moles in final solution = n = n1 + n2
So,
n = 1.2 + 1.485 = 2.685 mol
Now
Total volume is
= V = V1 + V2
= 2.0 +0.495
= 2.495 L
Now
Molarity of final solution = n / V
= 2.685 / 2.495
= 1.0761 M
= 1.1

Explanation:
The A horizon, known as the topsoil, is essential for plant production due to its rich organic content, while the B horizon, or subsoil, is denser and stores inorganic nutrients.
Explanation:Topsoil is considered the A horizon, consisting of partially decayed organic matter that enhances soil moisture retention, while the Subsoil is the B horizon, a dense layer with inorganic nutrients accumulation.
In understanding soil composition and structure, it's crucial to identify the different layers or horizons that make up the soil profile. The topsoil is referred to as the A horizon, which is the layer where the soil possesses a mixture of organic material and inorganic products of weathering. This horizon is typically dark due to the presence of organic matter, making it highly crucial for plant production as it retains water and facilitates oxygen diffusion necessary for root respiration. Below the topsoil lies the subsoil, known as the B horizon. This layer accumulates mostly fine material that has been translocated downwards from the A horizon, making it denser. The subsoil is critical for the storage of inorganic nutrients but is lighter in color and has fewer organic materials compared to the topsoil.
