Answer:
C + D
Explanation:
C + D are the reactants because they are on the right side of the equation

Based on the data given in this question, the statement that shows a correct interpretation of the chemical reactions is as follows: reaction A was exothermic and reaction B was endothermic.
<h3>What are endothermic and exothermic reactions?</h3>
Endothermic reaction is a chemical reaction that absorbs heat energy from its surroundings while exothermic reaction is a reaction that releases energy in the form of heat.
Endothermic reactions leave their surroundings cooler while exothermic reactions leave their surroundings hotter.
According to this question, the initial and final temperatures of two reactions are given as follows:
- Reaction A: 25.1°C and 30.2°C
- Reaction B: 25.1°C and 20.0°C
From the above data, reaction A was exothermic because it increased the surrounding temperature and reaction B was endothermic because it reduced the surrounding's temperature.

Answer:
A
Explanation:
An unbalanced force is your answer.
This is an exercise in the general or combined gas law.
To start solving this exercise, we must obtain the following data:
<h3>Data:</h3>
- V₁ = 4.5 l
- T₁ = 33 °C + 273 = 306 k
- P₁ = 6.54 atm
- T₂ = 94 °C + 273 = 367 k
- V₂ = 2.3 l
- P₂ = ¿?
We use the following formula:
- P₁V₁T₂ = P₂V₂T₁ ⇒ General Formula
Where
- P₁ = Initial pressure
- V₁ = Initial volume
- T₂ = Initial temperature
- P₂ = Final pressure
- V₂ = Final volume
- T₁ = Initial temperature
We clear the general formula for the final pressure.
We solve by substituting our data in the formula:
If I raise the temperature to 94°C and decrease the volume to 2.3 liters, the pressure of the gas will be 15,346 atm.
