The chemical reaction that gives off 2100 Kg of heat energy has 501.9126 calories
calculation
convert KJ to calories
that is
1 KJ = 0.239006 calories
2100KJ= ? calories
by close multiplication
= (2100 kj x 0.239006)÷ 1 kj =501.9126 calories
To prevent the gaseous product from escaping, the system must be sealed.
<h3>What are equilibrium and an example?</h3>
Equilibrium is characterized as a state of equilibrium or a stable situation in which conflicting forces balance one another out and no changes are taking place. In terms of economics, equilibrium occurs when supply and demand are equal. When you are composed and steady, you are in an equilibrium state.
<h3>What three types of equilibrium are there?</h3>
Equilibrium can be classified as either stable, unstable, or neutral.
<h3>Which four variables have an impact on equilibrium?</h3>
- Equilibrium is influenced by the system's temperature, pressure, and concentration.
- When one of these variables changes, the system's equilibrium is upset and it readjusts itself until it reaches equilibrium again.

Answer:
<u></u>
Explanation:
<h2>Problem 1. </h2>
<u>a) Data:</u>
- n₁ = 0.126 mol
- V₁ = 2.74 L
- n₂ = 0.126mol + 0.124mol
- V₂ = ?
- Conditions: constant temperature and pressure
<u>b) Physical principles:</u>
The volume occupied by a gas, when the temperature and pressure remain unchanged, is proportional to the number of moles of gas.

<u>c) Solution:</u>
Solve for V₂ , substitute and compute:

<h2>Problem 2.</h2>
<u>a) Data:</u>
- n₁ = 0.547mol
- V₁ = 295 mL
- V₂ = ?
- n₂ = 0.547mol + 0.342 mol
- Conditions: constant temperature and pressure
<u>b) Physical principles:</u>
The same as above: the volume occupied by a gas, when the temperature and pressure remain unchanged, is proportional to the number of moles of gas.

<u>c) Solution:</u>
Solve for V₂ , substitute and compute:
