Question

When lithium nitride, Li3N(s) , is treated with water, H2O(l) , ammonia, NH3(g) , is produced. Predict the formula of the gas produced when sodium phosphide, Na3P(s) , is treated with water. formula: Write the balanced equation for the reaction of Na3P(s) with H2O(l) . Phases are optional.

Answer 1

Answer:

The formula of the gas produced is$PH_3$, and the balanced equation is :

$Na_3P(s)+3H_2O(l)\rightarrow 3NaOH(aq)+PH_3(g)$

Explanation:

The chemical reaction between lithium nitride and water gives lithium hydroxide and ammonia gas. The chemical equation of this reaction will be given as:

$Li_3N(s)+3H_2O(l)\rightarrow 3LiOH(aq)+NH_3(g)$

And when sodium phosphide reacts with water is gives an aqueous solution of sodium hydroxide and hydrogen phosphide gas also called phosphine gas.

The chemical equation of this reaction will be given as:

$Na_3P(s)+3H_2O(l)\rightarrow 3NaOH(aq)+PH_3(g)$

The formula of the gas produced is$PH_3$, and the balanced equation is :

$Na_3P(s)+3H_2O(l)\rightarrow 3NaOH(aq)+PH_3(g)$
