A.is an example of decomposition reaction.
This is a question that would have literally have taken two seconds to look up on google but the answer is 1.88 years.
gamma radiation and heat flares from the sun, they use refelective gold sheets
The amount of heat required is B) 150 J
Explanation:
The amount of heat energy required to increase the temperature of a substance is given by the equation:

where:
m is the mass of the substance
C is the specific heat capacity of the substance
is the change in temperature of the substance
For the sample of copper in this problem, we have:
m = 25 g (mass)
C = 0.39 J/gºC (specific heat capacity of copper)
(change in temperature)
Substituting, we find:

So, the closest answer is B) 150 J.
