Question

how to complete the chemical equation

Answer 1

Reactant1 + reactant2=product

Example : H2 +Cl2 = HCL

Balance the equation now

El LHS RHS

H 2 1×2

Cl 2 1×2

Therefore, H2 + Cl2 =2HCL

Hope so it helps.....

Bye have a nice day

Answer 2

Chemical equations are solved by writing the reactants on the left hand side of an arrow '⇒' followed by the product formed on the right hand side.

Reactants ⇒ Products

Reactant 1- NaOH

Reactant 2- HCl

Product 1- NaCl

Product 2- $H_{2}O$

Chemical equation-

             NaOH + HCl ⇒ NaCl + $H_{2}O$
