A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture.
A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
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
Answer:
the answer is D i believe. i am not shure but im like 70% sure
