1. List three factors that can cause a chemical reaction to proceed faster. 2. Raising the temperature of a reaction mixture is the same as increasing theof the reacting molecules.
3. A student mixes compound A with compound B and notices that a chemical reaction occurs. The temperature of the mixture decreases. The reaction is .
4. The temperature of the mixture decreases. The reaction is. Reactions that release energy, like the burning of coal, are called:.
A. Thermodynamic.
B. Exothermic.
C. Endothermic.
D. Thermotropic.
E. Ergonomic.
5. Which of the following is an endothermic process?
A. Freezing of water.
B. Evaporation of water.
C. Explosion of dynamite.
D. Burning wood.
E. Metabolism in animals.

Explanation:

1. The three factors are;

- Increasing the surface area of the reactants

- Using a catalyst

- Increasing temperature

2. Raising the temperature of a reaction mixture is the same as increasing the kinetic energy of the reacting molecules.

3. This reaction is an exothermic reaction. In exothermic reaction, the temperature of the system (mixture) decreases while that of the surroundings increases.

4. Reactions that releases energy to the surroundings are exothermic reactions.

5. All the options is an example of exothermic process because heat is being removed from the system except;

B. Evaporation of water - This is because it must absorb heat from the surroundings making it endothermic.

b) mutualism

hope this : )

i think it is true since you can test the answer and can use observations to complete it.
