Answer:
As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate. Hence the reaction rate of virtually all reactions increases with increasing temperature
HOPE THIS HELPED!!!!!!!!!!!!!! XDDDDD

Wear gloves when handling chemicals.
Make sure that none of the liquids near the Bunsen burner are flammable.
Explanation:
The safety precautions the student must apply while completing his experiment is that he/she must wear gloves while handling the chemicals and they must make sure that none of the liquids near the Bunsen burner are flammable.
- Safety guidelines provides a detailed and careful way to carry out experiment and observations in the laboratory.
- This is all in a bid to accidents in the workspace.
- It is a good practices to wear gloves and laboratory coat while handling chemicals.
- Also make sure to put out the Bunsen burner when not in use.

Answer:
2.843 M
Explanation:
Molarity = moles / volume
<u>Milliliters to liters:</u>
500 mL <u>= .500 L</u>
<u>Grams to moles:</u>
MgO molar mass = 16.00 + 24.31 = 40.31 g/mol
57.3 g x 1 mol / 40.31 g = <u>1.421 mol</u>
<u>Molarity:</u>
1.421 mol / .500 L = 2.843 M
