Its important because the temp can either take away or add energy to a substance.

Time taken = 3 hours
<h3>Further explanation</h3>
Given
speed : 75 mph
distance : 225 miles
Required
time taken
Solution
An equation of constant velocity motion
d = distance = m
v = speed = m / s
t = time = seconds
Input the value :
t = d : v
t = 225 miles : 75 miles/hour
t = 3 hours
Because Nickel is a transition metal that has more than one oxidation number (or charge) whereas magnesium always has a +2 charge.
