Question

Ca+O2-Cao BALANCE THE EQUATION​

Answer 1

Answer:

2Ca + O2 -----> 2CaO

Explanation:

Since there are 2 Oxygen atoms in LHS and one atom in RHS, we write 2 in front of CaO.

But there are 2 Ca atoms in RHS, we have to write 2 in front of Ca to balance it.

So now it is balanced.

Answer 2

The balanced equation will be as follows

$2Ca + O_{2}$ ⇒ $2CaO$

• When 2 moles of Ca reacts with one mole of O₂, it gives 2 moles of CaO.
• When calcium reacts with oxygen it forms Calcium oxide which is also known as Quick lime.
• The chemical equations are balanced due to the law of conservation of mass.
• We can simply balance the chemical equations by adding a suitable coefficient before the compound or element.
• The balanced equation will be

         $2Ca + O_{2}$ ⇒ $2CaO$
