Answer:
I think the answer is A!!!
Answer:
a. 342.9 kJ of heat are absorbed.
Explanation:
Calculation of the moles of 
as:-
Mass = 20.00 g
Molar mass of = 17.031 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given that:- 
It means that 1 mole of undergoes reaction and absorbs 1168\ kJ of heat
So,
1168 mole of undergoes reaction and absorbs 
of heat
<u>Amount of heat absorbed = + 342.9 KJ</u>
