Question

Consider the following two unbalanced reactions:
KCIO3
→ KCI + O2
Mg + O2 → Mgo
The number of moles of Mgo produced when
oxygen produced by 1 mole of KCIO3 is completely
reacted with Mg is
(1) 1 mole
(2) 2 mole
(3)3 mole
(4) 4 mole​

Answer 1

Answer:

1 mole

Explanation:

because mole of KClO3 is 1.

number of mole of oxygen produced is also 1.

then number of mole of MgO produced is also 1.

Answer 2

Explanation:

2moles

Mg+O2 gives 2MgO
