Magnesium burns in air with a dazzling brilliance to produce magnesium oxide: 2mg(s) + o2(g) → 2mgo(s) how many moles of o2 are consumed when 0.550 mol of magnesium burns?

0.275 moles of oxygen gas is consumed in the reaction.

Explanation:

We are given:

Moles of magnesium = 0.550 moles

For the given chemical reaction:

By Stoichiometry of the reaction:

2 moles of magnesium reacts with 1 mole of oxygen gas.

So, 0.550 moles of magnesium will react with = of oxygen gas.

Hence, 0.275 moles of oxygen gas is consumed in the reaction.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
