How many grams of MgO can be produced with 4.63 grams of oxygen (O2)?

2Mg+O2=2MgO

11.6 grams of MgO can be produced with 4.63 grams of oxygen.

Explanation:

Mass of oxygen gas = 4.63 g

Moles of oxygen gas =

According to reaction,  1 mole of oxygen gas gives 2 moles of magnesium oxide, then 0.1447 moles of oxygen gas will giv e:

of magnesium oxide

Mass of 0.2894 moles of magnesium oxide:

= 0.29 mol × 40 g/mol = 11.6 g

11.6 grams of MgO can be produced with 4.63 grams of oxygen.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

gas

explanation:

smoke is the matter of a gas
