Make four different test groups.

Test 1: Add 10mL of A to 10mL of B, and insert substance X into the reaction. Record the time.

Test 2: Add 10mL of A to 10mL of B, and insert substance Y into the reaction. Record the time.

Test 3: Add 10mL of A to 10mL of B, and insert substance Z into the reaction. Record the time.

Test 4: This is your control group. Only add 10mL of A to 10mL of B, then record the time for the reaction to occur.

The catalyst is which ever substance caused for the reaction time to speed up. I hope that this helped! Please leave brainliest!

___________________________________________
Explanation:
__________________________________________________________
 →  2ⁿ  = ? ;  {that is: "2" , raised to the "n th" power, equals {<u>what value</u>} ?
___________________________________________
 → Note that "n" is the haploid number, which is: 
                           "15" (value given within this very question).
__________________________________________________
→ So we plug in "15" for "n" ; to obtain the "final value" —
                                                          which is the answer.
__________________________________________________
           →  As such:  " 2¹⁵ = 32,768 " .  (using scientific calculator online).
