Energy is absorbed so, the mass is increased.
energy is released so, the mass is increased
Answer:
10.
Explanation:
Hello,
In this case, for the given reaction:
By knowing the law of conservation of mass must be respected, the following coefficients do balance the chemical equation:
So the sum of all the coefficients is 10.
Regards.
Because of the Law of Conservation of Energy, the heat loss plus the heat used to combust the sample should calculate to the actual heat capacity. A calorimeter is ideally an insulated vessel. However, in reality, heat is dissipated. Therefore, the heat capacity that we calculate in the experiment will always be less than the actual value. This is accounted by the heat lost.
