Consider the balanced equation
2 answers:
Answer : The mole ratio of to
is, 4 : 2
Explanation :
Mole ratio : It is defined as the ratio of number of moles of the substances whose ratio is to be calculated.
The given balanced chemical reaction is :
By stoichiometry of the reaction we can say that,
4 moles of ammonia reacts with the 3 moles of oxygen to produce 2 moles of nitrogen and 6 moles of water.
Hence, the mole ratio of to
is, 4 : 2

Option (a) is correct.
A reducing agent is the one which loses electrons to other substance and an oxidizing agent is one which accepts electrons.
Here, In
, Cr has oxidation number 6+ in the L.H.S of the equation, but on R.H.S its oxidation number is 0 i.e. it Cr has gained electrons such that total charge is 0.
And the oxidation state of Al in the left-hand side of equation is 0 and in right-hand side, it is +6.i.e. it has donated its electrons to Cr.
Hence, Cr is the oxidizing agent and Al is the reducing agent.
