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.

yes it is balanced

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
