The internal energy for the oxidation of Mg has to be determined Concept Introduction: Heat energy required to raise the temperature of 1g of substance by 1K..Energy gained or lost can be calculated using the below equation. q=C×m×ΔT Where, q= energy gained or lost for a given mass of substance (m), C =specific heat capacity, ΔT = change in temperature. Sum of all energies transferred as heat in the system q r + q bomb + q water =0

Interpretation Introduction
Interpretation:
The internal energy for the oxidation of Mg has to be determined
Concept Introduction:
Heat energy required to raise the temperature of 1g of substance by 1K..Energy gained or lost can be calculated using the below equation.
q=C×m×ΔT
Where, q= energy gained or lost for a given mass of substance (m), C =specific heat capacity, ΔT= change in temperature.
Sum of all energies transferred as heat in the system
qr+qbomb+qwater=0
(b)
Interpretation Introduction
Interpretation:
The change in internal energy in the system has to be calculated.
Concept Introduction:
Standard enthalpy of the reaction,ΔrHo, is the change in enthalpy that happens when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.
Enthalpy change for the reaction ΔrH0=ΣnΔfH0(products)-ΣnΔfH0(reactants)
