Using standard heats of formation found in the appendix in your textbook, what is δh∘rxn for the following process. 2al3+(aq)+3cl2(g)→2alcl3(s)

The enthalpy of the reaction is coming out to be -361.86 kJ.

Explanation:

Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles. It is represented as

The equation used to calculate enthalpy change is of a reaction is:  

For the given chemical reaction:

The equation for the enthalpy change of the above reaction is:

We are given:

Putting values in above equation, we get:

Hence, the enthalpy of the reaction is coming out to be -361.86 kJ.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
