Answer:Moles of Mg, Cl, 0 = 5.40, 10.80, 43.2
Explanation:
1 mole of Mg(ClO4)2 contains 1 mole of Magnesium, Mg atoms
2 Moles of Chlorine, Cl atoms
8 Molresof Oxygen atoms
Such that to find the number of moles of each element, We have that
------1 mole Magnesum atoms/ 1 mol of Mg(ClO4)2 x 5.40 moles of magnesium perchlorate, Mg(ClO4)2 = 1 x 5.40 =5.40 moles
------2 moles ofChlorine atoms/ 1 mol of Mg(ClO4)2 x 5.40 moles of magnesium perchlorate, Mg(ClO4)2 = 2 x 5.40 = 10.80 moles
------8 moles Oxygen atoms/ 1 mol of Mg(ClO4)2 x 5.40 moles of magnesium perchlorate, Mg(ClO4)2 = 8 x 5.40 = 43.2 moles
If you burn a candle, it's mass will decrease. If that's the case you have changed a physical property of the candle.
Burning anything is always a chemical change Gasoline ( a hydrocarbon) burns in oxygen to produce water and carbon dioxide.
