Question

..Writ the balanced chemical equations for the following reactions:-
a) sodium reacts with oxygen
b) aluminum reacts with dilute hydrochloric acid.​

Answer 1

Here is your solution⬇️

$\bold{\red{\boxed{\boxed{\huge\underline{1.}}}}}$

$\bold{\red{sodium\: react \:with\: oxygen}}$

Na+o2----------->Na20

$\underline{\purple{\bold{Now\:we \:balance\: reaction. }}}$

2Na+o2----------->Na20

This is balance chemical reactions .

$\bold{\purple{\boxed{\boxed{\huge\underline{2.}}}}}$

$\bold{\red{Aluminium\: react \:with\: dilute}}$

$\bold{\red{Hydrochloric\: acid.}}</h3><h3>$

Al + Hcl -------> Alcl3+H2

$\underline{\purple{\bold{Now\:we\:balance \:reaction.}}}$

2Al + 6Hcl -------> 2Alcl3+3H2

This is balance chemical reactions.
