What is the equation for heat of CuCO3 and heat of Pb(NO3)2.

To find the equation for the heat of reaction for a given chemical reaction, you need to start with the balanced equation for the reaction.

For the decomposition of copper(II) carbonate (CuCO3), the balanced equation is:
CuCO3 (s) → CuO (s) + CO2 (g)

For the reaction of lead(II) nitrate (Pb(NO3)2), consider if you want to find the heat of reaction for a specific reaction or a decomposition reaction involving Pb(NO3)2. If you have a specific reaction in mind, provide that information for a more accurate answer.

The heat of reaction (ΔH) is typically given in kilojoules per mole of the reaction. To calculate the heat of reaction, you would need the specific heat values associated with the reactants and products involved in the reaction, as well as the balanced equation.

Once you have the balanced equation and the specific heat values, you can apply Hess's law or use thermochemical equations to calculate the heat of reaction.

It is important to note that without specific heat values or additional information, it is not possible to provide the exact equation for the heat of reaction for CuCO3 or Pb(NO3)2.
