Question

Hi! everyone, It's me, Ayesha Khan having one problem please help me find out the answer...

Answer 1

Answer:

$\small \sf \: 4NH_3 + 5O_2 \rightarrow 4NO + 6H_2O \\ \small \sf \: 2 KNO_3 \rightarrow 2 KNO_2 + O_2 \\ \small \sf \: Ca + 2 H_2O \rightarrow \: Ca(OH)_2 + H_2 \\ \small \sf \: 2NaHCO_3 \rightarrow Na_2CO_3 + H_2O + CO_2 \\ \small \sf \: 2 CO + O_2 \rightarrow \: 2 CO_2$

Explanation:

A) When four moles of ammonia reacts with five moles of O2 gas, four moles of Nitrogen mono oxide liberates along with six moles of water.

$\sf \: 4NH_3 + 5O_2 \rightarrow 4NO + 6H_2O$

B) When two moles pottasium nitrate (KNO3) is heated it dissociates into two moles of potassium nitrite liberates along with one mole of O2 gas.

$\sf \: 2 KNO_3 \rightarrow 2 KNO_2 + O_2$

C) When one mole of calcium reacts with two moles water, one mole of calcium hydroxide obtained & one of hydrogen gas released.

$\sf \: Ca + 2 H_2O \rightarrow \: Ca(OH)_2 + H_2$

D) When two mole of Sodium bicarbonate (NaHCO3) is heated it gradually decomposes to one mole of Sodium carbonate (Na2CO3) obtained along with one mole of each Water & Carbon dioxide.

$\sf \: 2NaHCO_3 \rightarrow Na_2CO_3 + H_2O + CO_2$

E) The question needs to corrected,

When two moles of carbon monoxide reacts with one mole oxygen two moles of carbon dioxide is released.

$\sf \: 2 CO + O_2 \rightarrow \: 2 CO_2$
