<u>Answer:</u> The correct answer is first; some of the energy disperses as heat.
<u>Explanation:</u>
First law of thermodynamics states that energy is always conserved in a system which means that energy can neither be created, nor be destroyed but it can only be transformed from one form to another.
Second law of thermodynamics states that all spontaneous processes are accompanied by increase in entropy or randomness.
Hence, the correct answer is first; some of the energy disperses as heat.
Explanation:Your body is constantly making, altering, and destroying chemical compounds, but they're so varied and complex that it's impossible to detect and count them all.
Acids are ionic compounds that produce positive hydrogen ions when dissolved in water. Acids taste sour. They conduct electricity when dissolved in water. They also react with metals to produce hydrogen gas.
