The pH will decrease because lemon juice is very acidic meaning it would bring the pH level down to a more acidic value.

The ATP molecule is a high energy molecule. When a molecule of ATP breakdown, it produces chemical as well as thermal energy. The type of energy produced is mainly depends on the application for example, if the ATP breaks down to ADP, it produces thermal energy and if couples with a cellular process it produces chemical potential.
Our body needs energy to carry out cellular functions and the energy produced in a form of ATP is taken by cells to perform functions.
2NH3 is equivalent to N2 + H6 since the 2 at the beginning gets distributed to both atoms. Knowing this you can rewite the equation as
H2 + N2 = H6 + N2
The N2 can cancel out leaving
H2 = H6
You now have to ask ‘2 times what equals 6?’ The answer is obviously 3 at this point.
Answer: C. 3
