Answer : The reaction will produce (B) 1.57 mole of magnesium hydroxide and (D) 3.14 mole of sodium chlorate.

Explanation :

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

Mg(ClO_3)_2+2NaOH\rightarrow Mg(OH)_2+2NaClO_3

From the balanced reaction we conclude that

As, 1 moles of Mg(ClO_3)_2 react with 2 mole of NaOH

So, 2.72 moles of Mg(ClO_3)_2 react with 2\times 2.72=5.44 moles of NaOH

That means, in the given balanced reaction, NaOH is a limiting reagent because it limits the formation of products and Mg(ClO_3)_2 is an excess reagent.

Now we have to calculate the moles of Mg(OH)_2 and NaClO_3 by using the moles of limiting reagent.

As, 2 moles of NaOH react to give 1 mole of Mg(OH)_2

So, 3.14 moles of NaOH react to give \frac{3.14}{2}=1.57 moles of Mg(OH)_2

And,

As, 2 moles of NaOH react to give 2 mole of NaClO_3

So, 3.14 moles of NaOH react to give 3.14 moles of NaClO_3

Therefore, the reaction will produce (B) 1.57 mole of magnesium hydroxide and (D) 3.14 mole of sodium chlorate.

Which of the following is an oxidation-reduction reaction? so2(g) h2o(l) right arrow. h2so3(aq) caco3(s) right arrow. cao(s) co2
Gennadij [26K]

The reaction which shows oxidation and reduction simultaneously is C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l).

<h3>What are redox reactions?</h3>

Those reaction in which oxidation as well as reduction of substances takes place simultaneously will known as redox reactions.

  • SO₂(g) + H₂O(l) → H₂SO₃(aq)
  • CaCO₃(aq) → CaO(s) + CO₂(g)
  • Ca(OH)₂(s) + H₂CO₃(l)  CaCO₃(aq) + 2H₂O(l)

Above reaction are not the redox reactions as in these reaction oxidation and reduction simultaneously not takes place.

  • C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(l)

In the above reaction reduction of oxygen takes place as its oxidation state changes from 0 to -2, and at the same time oxidation of carbon takes place as its oxidation state changes from 0 to +4.

Hence correct option is (4).
