Answer: 
is 1155 kJ
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done or by the system
w = work done by the system=
{Work done on the system is positive as the final volume is lesser than initial volume}
w =
(1kcal=4.184 kJ)
q = +1.1 MJ = 1100 kJ (1MJ=1000kJ) {Heat absorbed by the system is positive}
Thus is 1155 kJ
Answer:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Explanation:
The equation for the reaction is:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Dissociation of each compound
FeSO₄ → Fe²⁺ + SO₄⁻²
NaOH → Na⁺ + OH⁻
Fe(OH)₂ → Fe²⁺ + 2OH⁻
Na₂SO₄ → 2Na⁺ + SO₄⁻²
