Question

Write the reaction of hydrochloric acid with zinc metal sodium carbonate sodium hydrogen carbonate sodium hydroxide calcium oxide write the reaction of aluminum and zinc with sodium hydroxide

Answer 1

$\bold{HYDROCHLORIC \: ACID \: WITH}$

◼$\boxed{ZINC}$

When HCl is added to zinc metal, HCl by its acidic properties , when acid reacts with a metal it gives out hydrogen, will give hydrogen and zinc chloride .

$Zn + 2HCl \longrightarrow ZnCl_2 + H_2$

◼$\boxed{SODIUM \: CARBONATE }$

When HCl reacts with sodium carbonate it according to its acidic properties will give out carbon dioxide, water and a salt. So it gives out sodium chloride water and carbondioxide.

$Na_2CO_3 + 2HCl \longrightarrow 2NaCl + H_2O + CO_2$

◼$\boxed{SODIUM \: HYDROGEN \: CARBONATE }$

When HCl reacts with sodium hydrogen carbonate it according to its acidic properties will give out carbon dioxide, water and a salt. So it gives out sodium chloride water and carbondioxide.

$Na_2HCO_3 + 2HCl \longrightarrow NaCl + H_2O + CO_2$

◼$\boxed{SODIUM \: HYDROXIDE }$

When HCl reacts with sodium hydroxide which is a base, HCl according to its acidic properties will form salt and water due to neutralisation reaction.

$2NaOH + 2HCl \longrightarrow 2NaCl + 2H_2O$

◼$\boxed{CALCIUM\: OXIDE }$

When HCl reacts with sodium hydroxide which is a base, HCl according to its acidic properties will form salt and water due to neutralisation reaction.It will form calcium chloride and water.

$CaO + 2HCl \longrightarrow CaCl_2 + H_2O$

$\bold{SODIUM \: HYDROXIDE \: WITH}$

◼$\boxed{ALUMINUM }$

When sodium hydroxide reacts with aluminum it gives a complex salt sodium aluminate.

$2NaOH + Al \longrightarrow Na_2AlO_2 + H_2$

◼$\boxed{ZINC }$

When sodium hydroxide reacts with zincate it gives a complex salt sodium zincate.

$2NaOH + Zn \longrightarrow Na_2ZnO_2 + H_2$

Answer 2

HEY FRIEND HERE IS UR ANSWER,

Sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas.

                    Zn(s)+2NaOH(aq)+2H2O(l)→Na2Zn(OH)4(aq)+H2(g).
