State with reasons, whether sulphur dioxide is acting as an oxidizing agent or a reducing agent in each of the following reactio
evablogger [386]

Answer:

A) oxidizing agent is SO2

B) NaClO is the oxidizing agent

Explanation:

A) This is a redox reaction in which oxidation and reduction occur simultaneously.

Thus, in 2H2S(g) + SO2(g) -> 2H2O(l) + 3S(s);

H2S is reduced as follows;

H2S → S + 2H+ + 2e−

We can see that SO2 has been reduced while H2S gets oxidized since it has changed state from - 2 to 0 . Thus sulphur dioxide is the oxidizing agent.

B) SO2(g) + H2O(l) + NaClO(aq) -> NaCl(aq) + H2SO4(aq)

In this, SO2 undergoes oxidation and NaClO is the oxidizing agent

What will happen if 2.3 L of nitrogen gas is added to a 5 L flask that contains a mixture of carbon monoxide, oxygen, and carbon
stiks02 [169]

Answer:

The equilibrium will remain at the same conditions because there is no effect and difference in the partial pressure which in turn affect the equilibrium state.

Explanation:

  1. As Nitrogen is an inert gas therefore it will not react with either the reactants or products.
  2. Also as the addition is being made by maintaining the volume of flask as constant, thus there will be no difference in the partial pressure of the individual components of the mixture by addition of the Nitrogen gas.
  3. An increase in pressure is observed but the effect is not aiding or retreating the equilibrium conditions
