Answer:
Explanation:
1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.
2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.
3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.

Explanation:
Answer:
The answer is
<h2>25 mL</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass of CCl4 = 40g
Density = 1.6 g/mL
The volume is
We have the final answer as
<h3>25 mL</h3>
