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
