Ronch [10]

<u>Answer:</u> The gas produced when sodium phosphide reacts with water is phosphine.

<u>Explanation:</u>

When sodium phosphide reacts with water molecule, it leads to the production of flammable, poisonous gas known as phosphine along with the production of sodium hydroxide.

The chemical reaction for the reaction of sodium phosphide with water follows the equation:

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

By Stoichiometry of the reaction:

1 mole of sodium phosphide reacts with 3 moles of water to produce 1 mole of phosphine gas and 3 moles of sodium hydroxide.

Hence, the gas produced when sodium phosphide reacts with water is phosphine.

Classify each process as exothermic or endothermic.
IgorC [24]

1. Endothermic reaction

2. Exothermic reaction

3. Exothermic reaction

<u>Explanation:</u>

1. Evaporation of alcohol from the skin, here the heat is absorbed by the alcohol so that it gets evaporated from the skin and it is an endothermic process. As the reaction says that, the energy is added to the system, so it is endothermic.

C₃H₈O + 5.2 kJ → C₃H₈O(g)

2. Burning of propane in a gas grill:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O + 1652 kJ.

Here energy is released or given out which is termed as exothermic reaction.

3. Oxidation of iron to form rust:

4 Fe + 3O₂ → 2 Fe₂O₃ + 2221 kJ.​

Here also energy is released along with the products, so it is termed as exothermic reaction.

Whenever energy is absorbed, the reaction is endothermic in contrast if the energy is released then the reaction is exothermic.
