Answer:
3'008,757.5 Joules
Explanation:
First, calculate the hexane (Hx) moles:
Then, multiply the number of moles by the enthalpy of reaction (the enthalpy of reaction is given by mole of reactant):
Change to Joules:
It has negative sign due to its released energy, so the answer should be positive: 3'008,757.5 J
Explanation:
They are precise but not reproducible
Answer:
the correct formula is Na2O
<span>Cations mix with anions, so you know NH4+ won't mix with K+ and SO4(2-) won't miix with F-. For the reason that NH4+ and F- together have single charges, they'll mix in a 1:1 ratio, NH4F. There's two charges on SO4(2-), so it'll need two K+ to mix with, K2SO4.</span>
