D. In a Chemical reaction, elements are not changed, just rearranged. Small amounts of energy take place.
Heat energy can be calculated by using the
specific heat of a substance multiplying it to the mass of the sample and the
change in temperature. It is expressed as:
<span>Energy = mCΔT</span>
<span>Energy = 100 (0.90) (150 - 30)</span>
Energy = 10800 J
