In a popular classroom demonstration, solid sodium is added to liquid water and reacts to produce hydrogen gas and aqueous sodium hydroxide. part a write a balanced chemical equation for this reaction. express your answer as a chemical equation. identify all of the phases in your answer.

The chemical reaction is given below.

Explanation:

When solid sodium metal reacts with water molecule to produce aqueous sodium hydroxide and hydrogen gas. The equation for this follows:

By Stoichiometry of the reaction:

2 moles of solid sodium metal reacts with 2 moles of water molecule to produce 2 moles of sodium hydroxide and 1 mole of hydrogen gas.

Sodium metal is present in solid state, Water molecule is present in liquid state, Sodium hydroxide is present in aqueous state and hydrogen is present in gaseous state.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
