Water, because electrolysis is using electricity to break the bond of water to release 2 Hydrogens and the 1 Oxygen.
16 atoms of hydrogen and 8 atoms of oxygen
Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. Combustion reactions are almost always exothermic CO(g) + ½O2(g) → CO2(g) + 67.6 kcal
base from the reaction, the stoichiometric ratio is 1 mole CO produce 67.6 kcal so the anwer is - 67.6 kcal because is it exothermic
Answer:
97.994 g/mol
Explanation:
One molecule of H₃PO₄ contains three atoms of H, one of P, and four of O.
3H = 3 × 1.0079 u = 3.0237 u
1P = 1 × 30.974 u = 30.974 u
4O = 4 × 15.999 u = <u>63.996 u
</u>
Total = 97.994 u
One molecule has a mass of 97.994 u.
One mole has a mass of 97.994 g.
The molar mass of H₃PO₄ is 97.994 g/mol.
