Answer:</h3>
1026.05 kJ
<h3>
Explanation:</h3>
- The Quantity of heat is calculated by multiplying the mass of a substance by specific heat capacity and the change in temperature.
- However, condensation takes place at a constant temperature.
- Therefore, Quantity of heat is calculated by multiplying mass by the latent heat of vaporization.
In this case we are given;
Mass of steam as 454 g
To calculate the amount of heat released we must know the value of latent heat of vaporization;
The latent heat of vaporization of steam is 2260 J/g
Therefore;
Heat released, Q = 454 g × 2260 J/g
=1026040 Joules
But, 1000 joules = 1 kilo-joules
Thus, Q = 1026.04 kJ
Hence, the amount of heat released is 1026.05 kJ
1) The forward reaction is N2 (g) + O2 (g) → 2NO
(that reaction requires special contitions because at normal pressures and temperatures N2 and O2 do not react to form another compound.
2) The equiblibrium equation is
N2 (g) + O2 (g) ⇄ 2NO
3) Then, the reverse reaction is
2NO → N2(g) + O2(g)
Answer: 2NO → N2(g) + O2(g)
