ehidna [41]

Answer:

<u>reaction are equal.</u>

Explanation:

The law of the conservation of mass states that the total mass before and after a reaction are equal.

In a reaction, the mass of the reactants are always equal to the mass of the products. Nothing ever disappears from the equation, although substances may become gas and "disappear" the air.

you find that 7.36g of a compound has decomposed to give 6.93g of oxygen. the only other element in the compound is hydrogen. if
slavikrds [6]
First solve the moles of oxgen present in the compound

mol O = 6.93 g O ( 1 mol O / 16 g O )
mol O = 0.43 mol H

then solve the moles of hydrogen present
mol H = ( 7.36 - 6.93) g H ( 1 mol H / 1 g H)
mol H = 0.43 mol H
so the O and H are in the same mole content so the molecular formula would be OH, but the molar mass will not satisfy. so the answer would be
H2O2
