! 20 points !need answer FAST! In nuclear reactions, how can huge amounts of energy be produced?
A. By converting chemical energy into nuclear energy
B. By releasing thermal energy in uranium
C. By creating energy from the surrounding space
D. By destroying matter to create energy

D.

Explanation:

With the Fat Boy and Little Boy nuclear bombs that were drop on Japan, They used a little gun (inside the bomb) that shot a little slug. this hit and caused a chain reaction that caused the bomb to detonate. This released much energy. Destroying much of the two cities when the bombs were dropped.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
