Two or three points here.
1. You can't get lazy in chemistry and not use the caps key. Those symbols don't mean anything to me.
2. -2984, -285.9, -1279 what units.
3. Calculate enthalpy change for what?
if enthalpies for formation of p4o10, h2o and h3po4 are -2984, -285.9 and -1279 respectively calculate the enthalpy change using hess's law
