What is the mole to mole ration between oxygen gas and water

The mole to mole ratio between oxygen gas and water is 2 : 1

Explanation:

Balancing is making the number of atoms of each element same on both the sides  (reactant and product side).

To find the number of atoms of each element we multiply coefficient and the subscript  

For example  

contains  

5 × 1 = 5 ,Ca atoms and

5 × 2 = 10, Cl atoms  

If there is a bracket in the chemical formula  

For example  

we multiply coefficient × subscript × number outside the bracket to find the number of atoms  

(Please note: 3 is the coefficient, and if there is no number given then 1 will be the coefficient )

So

3 × 3 = 9 , Ca atoms  

3 × 1 × 2 = 6, P atoms  

3 × 4 × 2 = 24, O atoms are present.

So

The balanced chemical equation is

The number which stands in front of the chemical formula is the coefficient and it represents the number of moles of each substance.

So we see here 2 is the coefficient of and 1 is the coefficient of  

So the mole ratio of water and oxygen gas is 2 : 1
