Answer:
0.4589J/g°C
Explanation:
Heat energy = 1050J
Mass of iron = 220.0g
Initial temperature (T1) = 10°C
Final temperature (T2) = 20.4°C
Heat energy = mc∇T
Q = mc∇T
Q = heat energy
M = mass of the substance
C = specific heat capacity of the substance
∇T = change in temperature = T2 - T1
Q = m×c×(T2 - T1)
1050 = 220 × c ×(20.4 - 10)
1050 = 220c × (10.4)
1050 = 2288c
c = 1050 / 2288
C = 0.4589J/g°C
The specific heat capacity of iron is 0.4589J/g°C
For this reaction, the reactants are nitrogen dioxide, oxygen and water while the product would be nitric acid. The chemical equation would be written as:
NO2(g) + O2(g) + H2O(l) --> HNO3(aq)
This can be a complete equation when the elements are balanced in each side.
4NO2(g) + O2(g) + 2<span>H2O(l) --> 4HNO3(aq)</span>
