Write the balanced chemical equations for the reaction of magnesium metal with oxygen gas, and for the reaction of magnesium met
Sunny_sXe [5.5K]
Magnesium element exists as single atoms. Free oxygen is always diatomic (two atoms bonded together) as O2. Nitrogen gas is also diatomic N2.

2Mg + O2 → MgO

Mg forms a +2 ion, O forms a -2 ion, so they combine and balance in a 1:1 ratio. MgO, magnesium oxide, is a solid. 
3Mg + N2→Mg3N2

Mg forms a +2 ion, but N forms a -3 ion. Hence the Mg3N2 configuration for magnesium nitride.

kaheart [24]

2 moles

Explanation:

Given parameters:

Mass of Sb = 243.52g

Unknown:

Number of moles = ?

Solution:

The number of moles of any substance can be calculated using the expression below:

 Number of moles = \frac{mass }{molar mass}

  Molar mass of Sb = 121.76g/mol

Now input the parameters:

   Number of moles = \frac{243.52}{121.76 } =  2 moles
