Ethyne, C2H2, is a common fuel used in the welding industry. The equation for the complete combustion of ethyne is given below.2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(ℓ) ∆rH = –2610 kJ mol–1Calculate the mass of C2H2(g) needed to release 11400 kJ of heat energy. M(C2H2) = 26.0 g mol–1

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

increased stability in the completion of fluorine's outer shell.
