Question

Draw the electron dot structure of the gas molecule which is liberated when zinc metal is treated with aqueous NaOH solution.

Answer 1

Hydrogen gas gets liberated in the reaction you stated above

$2NaOH+Zn$ --->$Na_{2}ZnO_{2}+H_{2}$

Answer 2

Hydrogen gas is liberated when zinc metal is treated with aqueous NaOH solution.

• Zinc is a chemically active metal which can perform various kinds of chemical reactions.
• The zinc metal can also react with NaOH solution,
• In this chemical reaction sodium zincate and hydrogen gas are produced. [ Zn + NaOH ---> Na2ZnO2 + H2]
• The diagram of the electron dot structure of hydrogen gas is attached with this answer.
