When a chemical reaction happens

bonds must be broken and reformed

chemicals keep their same properties

Which example provides evidence of a chemical change?

Wood releases ash and smoke when burned.

Rock particles separate when soil is being sifted.

Boiling water bubbles when being heated.

Sugar is not visible when dissolved in water.

Two liquids are mixed together. Which of the following does NOT identify the formation of a new substance?

One liquid dissolves into the other.

Which of the following statements BEST describes COLLISION THEORY?

A. Atoms or molecules must collide with a sufficient amount of energy in order to react.

B. Catalyst can be recovered unchanged at the end of process.

C. Increasing the concentration of a reactant increases the rate of reaction.

D. Smaller pieces have a greater surface area, thus, providing much greater contact among the reactants and effecting more collisions.

7. How will crushing a solid into a powder increase the reaction rate?

D. The powdered form has more surface area.

A. The activation energy barrier will be lowered.

B. The orientation of colliding particles will be improved.

C. The particles will collide with more energy.

How could we make this reaction happen more quickly?

crush the chalk to increase the surface area

Decrease the concentration of the acid

Put the test tube in an ice bath

Add water to dilute the acid, thereby reducing its concentration so it can get between the chalk particles.

Why does a higher temperature increase the rate of a reaction?

it increases both the frequency and energy of particle collisions

it only increases the frequency of particle collisions

it only increases the energy of particle collisions

it reduces the activation energy of the reaction

To slow down a chemical reaction you will do one of the following:

Place the reactants in a ice bath

Place the reactants in hot water

Keep stirring the reactants with a stirring rod
