Astudent mixes chemicals a and b together and records the amount of time it takes for a color change to occur. the student repeats the process 5 more times each time changing the amount of chemical b used in the mixture. the independent variable in this experiment is the? amount of chemical b amount of chemical a time the color change

Option a) amount of chemical b

Step-by-step explanation:

Given that a  student mixes chemicals a and b together and records the amount of time it takes for a color change to occur. the student repeats the process 5 more times each time changing the amount of chemical b used in the mixture.

Since the student changes first the amount of chemical b used this is the independent variable x here.

y the dependent variable is the color change.

So answer is

Option a) amount of chemical b

step-by-step explanation: examine the two-step equation.
