Answer: Oxygen
Explanation:
As seen from the balanced equation:
2 moles of hydrogen combine with 1 mole of oxygen or 1 mole of hydrogen combine with 1/2 mole of oxygen.
According to Avogadro's law, equal volumes of gases contain equal number of molecules and hence equal number of moles.
Thus if x moles of both gases are present, x moles of hydrogen will combine with moles of oxygen and
moles of oxygen will be left used and will be in excess.
Answer: 633.6 g of can be produced from the decomposition of 4.8 moles of
Explanation:
The balanced chemical equation for decomposition of is :
According to stoichiometry :
1 mole of produce = 3 moles of
Thus 4.8 moles of will rproduce=
of
Mass of
Thus 633.6 g of can be produced from the decomposition of 4.8 moles of
