The temperature of a substance is related to the speed of the substance's particles. So, when the temperature of a substance changes,the speed of the particles also changes. So B.
He has to use a different colored light at a higher frequency.
Answer:
Explanation:
use the equation
moles = mass/mr
=19.9/79.5
=0.250moles of CuO

=2.02
so CuO is the limiting reagent because there is less amount of it.
