There are no states in the picture, but Na should have a "(s)" after it, and Cl2 should have a "(g)" after it. NaCl should have an "(s)". Chlorine is a diatomic element so it has a "2" subscript on it.
Hope this helped! :)
<u>Answer:</u>
<em>The mole to mole ratio between oxygen gas and water is 2 : 1</em>
<em></em>
<u>Explanation:</u>
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
(Answer)
A reversible reaction is a reaction that takes place in the ( formation of reactants to products and products to reactants simultaneously ). If the reaction were to ( be in dynamic equilibrium ), the rate of forward reaction would be equal to that of the reverse reaction.

No, they do not. Hope I helped! :)
