Answer:

NH3 < NF3 < BCl3

Explanation:

The vapour pressure of a substance has something to do with the nature of intermolecular forces between its molecules. If the molecules of a substance are held together by strong intermolecular forces, the substance will display a low vapour pressure at a given temperature and vice versa.

Ammonia has the lowest vapour pressure because of strong intermolecular hydrogen bonds that hold its molecules together.

When lithium nitride, Li 3 N ( s ) , is treated with water, H 2 O ( l ) , ammonia, NH 3 ( g ) , is produced. Predict the formula

allochka39001 [22]

Answer : The formula of the gas produced is, $PH_3$ (phosphine gas)

Explanation :

According to the question, when sodium phosphide is treated with water then it react to give phosphine gas and sodium hydroxide.

The balanced chemical reaction will be:

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

By Stoichiometry of the reaction we can say that:

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

Thus, the formula of the gas produced is, $PH_3$ (phosphine gas)

Consider the following oxidation-reduction reaction: 2fe3+(aq) + 2hg(l) + 2cl−(aq) → 2fe2+(aq) + hg2cl2(s). indicate the oxidizi

nirvana33 [79]

Answer:

The reducing agent is Hg (mercury) and the oxidixing agent is Cl (chlorine)

Explanation:

first find the oxidation charges of each of the different ions. All elements that are alone have a charge of 0. As you compare the reactants and products we can see that the chargers of Hg and Cl have changed.

Hg went from a charge of 0 to a charge of +1

Cl went from a charge of 0 to a charge of -1

remember when a substance gains electrons it is reducing and when a substance is losing electrons it is oxidizing.
