Answer:
Hello, Your answer is <em>B) Making observations</em>
<u><em>(Hope That Helps Your Answer)</em></u>
<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.

Answer:
Water- 9.982 grams
toluene-8.669 grams
chloroform - 14.832 grams
Explanation:
the units of density are listed as g/mL. So for every mL of substance you have, you will have that many grams.
Water- .9982g/mL * 10 mL
As you can see, the units of "mL" cancel each other out, leaving just the gram amount of water.
