O words Question 6 3 pts 6. Magnesuim + Oxygen > Magnesium oxide When 55g of magnesium is oxidized by the presence of oxygen,

Answer 1

Answer #1

This is balanced equation when magnesium is oxidized,product formed is magnesium oxide

2Mg +O2 $\rightarrow$ 2MgO

molar mass of Mg=24.305 g/mol

Moles of Mg= given mass/molar mass

given mass=55 g

moles of Mg = 55 g/[24.305 g /mol]=2.2629 moles of Mg

From balanced equation

2 moles of Mg produce 2 moles of MgO

2.2629 moles of Mg will give [2 moles of MgO][2.2629 moles of Mg]/[ 2 moles of Mg]= 2.2629 moles of MgO

[ Unit of moles of Mg get cancelled in numerator and denominator]

Answer= 2.2629 moles of product that is MgO is formed

Answer 2
