Question

Mention the physical states of the reactants and products of the following chemical reaction and balance the equations. ( a) C6H12O6=> C2H5OH+ CO2 (b) NH3+CO2=>N2+NH4CI (C) Na+H2O=> NaOH+H2​

Answer 1

$\huge \mathfrak \red{Answer}$

$\tt(a) \: {C_{6}H_{12}O_{6} \: \Rightarrow \:{C_{2}H_{5}OH} \: + \: {CO_{2}}}$

$\tt \pink{Answer:} \: {C_{6}H_{12}O_{6}}\Rightarrow \:{2C_{2}H_{5}OH} \: + \: {2CO_{2}}$

This reaction is known as the reaction alcoholic fermentation of glucose.

$\tt(b) \: {NH_{3} + Cl_{2} \: \Rightarrow \:{N_{2}H_{4}} \: + \: {NH_{4}Cl}}$

$\tt\pink{Answer:}\: {8NH_{3}+ 3Cl_{2} \: \Rightarrow \:N — 2\: + \: {6NH_{4}Cl}}$

In this reaction 8 molecule of ammonia reacts with three molecule of chlorine to from nitrogen and six molecule of ammonium chloride.

$\tt(c) \: {Na + H_{2}O \: \Rightarrow \: NaOH\: + \: {H_{2}}}$

$\tt \pink{Answer : }\: {2Na \: + H_{2}O12 \: \Rightarrow \: NaOH\: + \: {H_{2}}}$

In this reaction sodium react with water molecule to form sodium hydroxide and hydrogen gas.
