Carbonic acid (H2CO3) is a polyprotic acid. Write balanced chemical equations for the sequence of reactions that carbonic acid can undergo when it's dissolved in water.
Answers
Answer:
H₂CO₃(aq) ⇄ H⁺(aq) + HCO₃⁻(aq)
HCO₃⁻(aq) ⇄ H⁺(aq) + CO₃²⁻(aq)
Explanation:
Carbonic acid (H₂CO₃) has 2 acidic protons. When is dissolved in water, it loses the protons (H⁺) in two sequential steps:
- First, it loses 1 proton to form the hydrogen carbonate ion (HCO₃⁻)
H₂CO₃(aq) ⇄ H⁺(aq) + HCO₃⁻(aq)
- Then, the acid carbonate anion loses its proton to form carbonate ion (CO₃²⁻):
HCO₃⁻(aq) ⇄ H⁺(aq) + CO₃²⁻(aq)

First, let's see the proportion of the chemical equation:
8 moles of HNO₃ need to react with 3 moles of Cu.
You have 2.0 mol of HNO₃, so you can use the rule of 3 to find out how many moles of Cu you will need.
8 moles of HNO₃ ----- 3 moles of Cu
2 moles of HNO₃ ----- x moles of Cu
8x = 3 × 2
x = 6/8
x = 0.75 moles of Cu.
But you need to find how many grams. To find out, you need to know what the atomic mass of Cu. You can consult the periodic table to find out, the atomic mass of copper is 63.6 g/mol.
Now you need to transform moles into grams:
63.6 g of Cu ---- 1 mol of Cu
x g of Cu ---- 0.75 mol of Cu
x = 63.6 × 0.75
x = 47.7 g
Answer: It is needed 48 g of Cu to react with 2.0 mol of HNO₃.
A certain reaction is exothermic in the forward direction and has a greater number of molecules on the product side. Which actions should be used to increase the yield of the products? aDecrease the temperature and decrease the pressure. bIncrease the temperature and decrease the pressure. cDecrease the temperature and increase the pressure. dIncrease the temperature and increase the pressure.
Answers
According to leChatelier's principle the equilibrium will be displaced to compensate any modifications to the equilibrium.
The text says it is an exothermic reaction, therefore decrease the temperature will force the equilibrium to the righthand side.
They also said that the number of molecules is greater on the product side, which means that when the reaction moves to the right side the total pressure of the system will also increase. therefore decreasing the pressure will force the reaction to the right hand side.
This gives us option A as the right answer
You are asked to write observations about a 100g sample of Nitrogen-16 before it decays , but you running late. In order to make observations, you require at least 5g of material Can make observations you are 57 seconds late to the lab?
Answers
Answer:
You can not make the observation in the lab
Explanation:
We must know the amount of Nitrogen-16 that remains after 57 seconds before we can make our conclusion.
Hence, from;
N/No = (1/2)^t/t1/2
Where;
N = amount of Nitrogen-16 present after 57 seconds
No = 100g of Nitrogen-16 originally present
t = 57 seconds
t1/2 = half life of Nitrogen-16 which is 7.13 seconds
Substituting values;
N/100 = (1/2)57/7.13
N/ 100 =(1/2)^8
N/100 = 1/256
256N = 100
N = 100/256
N = 0.39 g
You can not make the observation because you need at least 5g of Nitrogen-16 and only 0.39 g is left after 57 seconds.
The minimum amount of sample required has been 5 grams, while the remaining sample has been 0.39 grams. Thus, it has not been possible to make the observations.
The half life can be defined as the time required for the sample to reduce to half of its initial concentration. The half life can be given as:
Amount remained = Initial amount \(\rm \times\;\dfrac{1}{2}^\dfrac{time}{Half-life}\)
The half life of nitrogen 16 has been 7.13 second.
The initial concentration of the sample has been 100 grams.
The concentration of sample remained after 57 seconds has been:
Amount remained = 100 \(\rm \times\;\dfrac{1}{2}^\dfrac{57\;sec}{7.13\;sec}\)
Amount remained = 0.39 grams.
The amount of sample remained after 57 seconds has been 0.39 grams.
The amount of sample required for the analysis has been 5 grams, after 57 seconds only 0.39 grams of sample has been remaining. Thus, the student will not be able to made analysis of nitrogen-16.

Initially, a 400.3 m³ spring-loaded piston-cylinder assembly contains R-134a at 600 kPa and 150°C. The refrigerant temperature was cooled to -30°C and the volume was 0.1 m³. Calculate the transfer and the work produced by the refrigerant during this process.
Answers
ΔU = Q - W
We can assume that the process is quasi-static and reversible, so there is no entropy change (ΔS = 0). Therefore, the heat added to the system is simply the heat transfer (Q) and can be calculated using the specific heat capacity of R-134a at constant pressure (cp):
Q = m * cp * ΔT
where m is the mass of R-134a, cp is the specific heat capacity at constant pressure, and ΔT is the temperature change.
To calculate the work done by the refrigerant, we can use the following equation:
W = -P * ΔV
where P is the pressure and ΔV is the change in volume.
First, we need to find the initial and final states of the refrigerant:
State 1: P1 = 600 kPa, T1 = 150°C, V1 = 400.3 m³
State 2: P2 = 600 kPa, T2 = -30°C, V2 = 0.1 m³
We can use the R-134a tables to find the specific volume and specific internal energy at each state:
State 1: v1 = 0.1532 m³/kg, u1 = 783.1 kJ/kg
State 2: v2 = 0.0044 m³/kg, u2 = 131.3 kJ/kg
The mass of R-134a can be calculated from the initial volume and specific volume:
m = V1 / v1 = 400.3 m³ / 0.1532 m³/kg = 2614.4 kg
The heat transfer can be calculated as:
Q = m * cp * ΔT = m * cp * (T2 - T1) = 2614.4 kg * 1.14 kJ/kg·K * (-30°C - 150°C) = -573876.48 kJ
Note that the negative sign indicates that heat is being removed from the system (the refrigerant is being cooled).
The work done by the refrigerant can be calculated as:
W = -P * ΔV = P1 * (V1 - V2) = 600 kPa * (400.3 m³ - 0.1 m³) = 240120 J
Note that we converted the pressure from kPa to Pa and the volume from m³ to m³ to obtain the correct units for work (Joules).
Therefore, the transfer of heat from the refrigerant during this process is -573876.48 kJ, and the work produced by the refrigerant is 240120 J.
What forms of energy are produced when
fossil fuels burn?
Answers
When fossil fuels burn, several forms of energy are produced, including:
Heat energy: The primary form of energy released during fossil fuel combustion is heat. Fossil fuels contain chemical energy stored for millions of years, and when they burn, this energy is released in the form of heat. The heat energy can be harnessed for various purposes, such as heating buildings or generating steam to drive turbines.
Light energy: Burning fossil fuels can also produce light energy in the form of flames or glowing embers. This light energy is a byproduct of combustion.
Mechanical energy: Heat generated by burning fossil fuels can be converted into mechanical energy. This is typically achieved by using heat to produce steam, which drives a turbine connected to a generator. The rotating turbine converts the heat energy into mechanical energy, which is further transformed into electrical energy.
Electrical energy: Through the process described above, burning fossil fuels can ultimately generate electrical energy. The mechanical energy produced by the turbine is converted into electrical energy by the generator. Electrical energy can power various devices, appliances, industries, and infrastructure.
It's critical to note that while burning fossil fuels can produce useful forms of energy, it also results in the release of carbon dioxide and other greenhouse gases. This contributes to climate change and environmental concerns. As a result, there is a global shift towards cleaner and renewable energy sources to mitigate these negative impacts.

A sample of compound B (also a clear, colorless gas) is analyzed and found to contain 5.19g carbon and 13.84g oxygen. Are these data an example of the law of definite proportions, the law of multiple proportions, or neither? What do these data tell you about substances A and B?
Answers
Answer:
law of multiple proportions
Explanation:
The law of multiple proportions states that, if two elements A and B, combine to form more than one chemical compound. Then the various masses of one element A, which combine separately with a fixed mass of element B are in simple multiple ratio.
We can see that the ratio of oxygen that combines with carbon in the two compounds( A and B) is 1:2. This demonstrates the law of multiple proportions.
The substances A and B must be CO and CO2 respectively.

What state of matter is every compound in for the chemical reaction? CH4 (g)+2 0₂ (g) -> CO₂(g) + 2 H₂0 (g
Answers
Answer:
CH4 (g) and O2 (g) are both in the gaseous state, while CO2 (g) and H2O (g) are also in the gaseous state.
In the above reaction, the reactants are in the gaseous state, and the products formed are also in the gaseous state.
Every compound in a chemical reaction can be in any state of matter like solid, liquid, or gas. In the reaction of methane and oxygen, the initial state of the reactants is in the gaseous form. The chemical reaction of methane and oxygen is given by the equation CH4 (g) + 2 O2 (g) -> CO2 (g) + 2 H2O (g).Here, methane and oxygen are the reactants, and carbon dioxide and water are the products. Methane (CH4) and oxygen (O2) react together in the presence of a spark or heat to produce carbon dioxide (CO2) and water (H2O).In the reaction, the methane gas combines with oxygen gas, which causes the release of heat energy and forms carbon dioxide gas and water vapor. Methane gas is a colorless and odorless gas that burns cleanly and is one of the primary components of natural gas.
The oxygen gas required for the reaction is available in the atmosphere. Carbon dioxide is a colorless gas with a faint odor and taste and is a significant component of the Earth's atmosphere. Water is a colorless, odorless, and tasteless liquid that is essential to life.The state of matter of every compound in a chemical reaction can change depending on the conditions in which the reaction occurs. For instance, a substance that is in the solid state at a lower temperature may melt into a liquid or boil into a gas at a higher temperature. Similarly, a liquid may freeze into a solid or vaporize into a gas under different conditions.

Answers
There are 0.9797 moles of chlorine atoms are there in 5.9 × 1023 molecules of carbon tetrachloride, CCl4
By dividing the number of moles by the Avogadro constant, one can get the total number of atoms or molecules in a sample.The mole idea is a useful way to indicate how much of a substance there is. Any measurement can be divided into two components: the magnitude in numbers and the units in which the magnitude is expressed.Even one gramme of a pure element is known to have an enormous number of atoms when working with particles at the atomic (or molecular) level. The mole concept is frequently applied in this situation. The unit of measurement that receives the most attention is the "mole," which is a count of a sizable number of particles.
Number of Atoms or Molecules = (Number of Moles) * (6.022*10²³)
Given:
Molecules of chlorine atom = 5.9 * 10²³
Avagadro constant = 6.022*10²³
Number of moles = Number of molecules/ Avagadro constant
= 5.9 * 10²³ / 6.022*10²³
= 0.9797
Hence, there are 0.9797 moles of chlorine atoms are there in 5.9 × 1023 molecules of carbon tetrachloride, CCl4.
