(A) nervous, muscular, skeletal
Answer:
3.3765 Mol O2
Explanation:
There is no work for this problem
Answer:

Explanation:
The activation energy represents the energy barrier that reagents must pass to transform into products (or products to transform into reagents in a reverse reaction)
For any reaction, the change in enthalpy is related to the activation energy by the equation

So, the activation energy for the reverse reaction is

Atomic mass is equal to the total number of electrons neutrons and protons
