Question

A substance X which is used as an antacid reacts with dilute hydrochloric acid to produce a gas Y which is used in one type of fire extinguisher. The substance X and gas Y respectively are

2 points

Na2CO3 and H2

NaHCO3 and CO2

NaHCO3 and H2

Na2CO3 and CO2

​

Answer 1

Answer:

NaHCo3 and Co2 is the answer

Answer 2

The substance X (Sodium Hydrogen Carbonate($\sf{NaHCO_3}$) which is used as an antacid reacts with hydrochloric acid to produce a gas Y(Carbon dioxide($\sf{CO_2}$) which is used in one type of fire extinguisher. So, The correct answer is:

$\large{ \boxed{ \rm{ \red{NaHCO_3 \: and \: CO_2}}}}$

Option - (D)

Explanation:-

• For treating excessive release of acid inside stomach, we use a mild base known to be Sodium bicarbonate or Sodium hydrogen carbonate.
• When this reacts with an acid, Carbon dioxide gas is released which its used as a fire extinguisher.
• The Co2 being heavier than O2 forms a blanket over the fire and cut off the supply of oxygen, And hence stops the fire from flowing.
