I used the equation exactly as directed and have checked my answer countless times, only to find that I am wrong according to my teacher. Then again, she is the type to get things wrong herself. It's so stressful, but this video at least helped me reaffirm my understanding.
For context, I found that Ca(OH)2 + 2H3AsO4 = Ca(H2AsO4)2 + 2H20 gives -130.2KJ/mol.

Is the formula for just this equation or it applies to everything equation?

explain why the value of the standard enthalpy of formation of carbon dioxide[g] & the standard enthalpy combustion of c[s] are same?

believe the answer is -1411 probably miss a negative thanks, this example is really great...

what is the solution if one of the standard heat formation is not present?

so is that answer the standard enthalpy?
