Exothermic reaction is where there is release of energy during a reaction
The enthalpy of exothermic reaction is negative
The relation between energy of products, reactants and enthalpy of reaction is
Enthalpy of reaction = sum of enthalpy of formation of products - sum of enthalpy of formation of reactants
.
As enthalpy of reaction is negative, it means the enthalpy of products is less than the enthalpy of reactants so answer is
:
In an exothermic reaction the energy of the product is less than the energy of the reactants.
Answer:
Water
Explanation:
Because water is very important
Explanation:
number of atoms = moles × avegadro number
so 5.55 × 10^2 = moles × 6.023 × 10^23
moles = 5.55 × 10^2 ÷ 6.023 × 10^23 = 9.214×10−22 moles
