Answer:
Explanation:
-Specific heat capacity is given by the formula:
Where:
is the heat gained or loosed by the substance
is the mass of the substance
is the specific heat of the substance
is the change in temperature
#We make c the subject of the formula and substitute to solve for it:
Hence, the specific heat capacity of the ice is

the amount of radioactive materials released into the environment.
number of disintegrations of radioactive atoms in a radioactive material over a period of time</span>
<h3><u>Answer;</u></h3>
It makes the reaction harder to start
<h3><u>Explanation</u>;</h3>
- <em><u>Activation energy is minimum amount of energy that is required for a reaction to start. Activation energy determines the rate of a chemical reaction such that the higher the activation energy, the lower the rate of chemical reaction and vice versa.</u></em>
- The source of activation energy needed to push chemical reactions forward is obtained from the surroundings. Catalyst speed up chemical reaction by lowering the activation energy. Therefore, catalysis is the increase in the rate of a chemical reaction by lowering its activation energy.
