Answer : The amount of heat needed is, 1188 J
Explanation :
Formula used :
where,
q = heat needed = ?
m = mass of copper = 55 g
c = specific heat capacity of copper =
= initial temperature =
= final temperature =
Now put all the given values in the above formula, we get:
Thus, the amount of heat needed is, 1188 J
Explanation:
1. Thermochemical equation is balance stoichiometric chemical equation written with the phases of the reactants and products in the brackets along with the enthalpy change of the reaction.
The given correct thermochemical reactions are:
2. Phase change affect the value of the enthalpy change of the thermochemical equation. This is because change in phase is accompanied by change in energy. For example:
In both reaction phase of water is changing with change in energy of enthalpy of reaction.
