Question

1.write down the equation and a balanced chemical equation for the reaction of magnesium with pure oxygen gas:

a)word equation:

b)Chemical equation:​

Answer 1

a)magnesium+oxygen=magnesium oxide

b)Mg+O2=MgO BALANCED=2Mg+O2=2MgO

Step-by-step explanation:

aMg+bO2=cMgO

Mg:a=c let a=c=1

O:2b=c

2b=c

2b=1

b=1/2

(a=1,b=1/2,c=1)2

a=2,b=1,c=2

2Mg+O2=2MgO
