Divide by the molar mass of HCl which is 36.5g/mol grams cancels out and you are left with 1.99 mol.
Answer:
what you've asked so I guess the answer will be 10 days
Answer:
25kJ
Explanation:
Given the initial energy to be 30kJ
The energy change from the initial energy to the peak energy = (65-30) kJ
= 35kJ
since the second energy change was a drop in energy it is regarded negative
= (55-65)
= -10kJ
Therefore total energy change
= (35-10)kJ
= 25kJ
