This is a Hess's law question!

Hess's law states that regardless if there are multiple steps in a reaction, the total enthalpy change for the reaction is the sum of all changes.

#### Explanation:

This the question you want

These are the equations given

Now you need to either

Multiply the equation by a - number to flip the equation

Multiply the whole equation by a number to get more of the product or reactant.

Cancel out like reactant with like products.

Here are my steps

Here I multiplied equation 2 by a negative number to flip the

question this changes the enthalpy value from being a negative number to a positive.

I also simplified

Now you just need to cancel out like terms

Now your left with

Add up all your Enthalpy Values

And that's your answer
