Step by step solution

01

Group 15 elements

Group 15 elements belonging to the nitrogen family. They include nitrogen, phosphorus, arsenic, antimony, bismuth, and moscovium.

The atomic numbers of the group 15 elements are as follows;

Nitrogen (N) = 7

Phosphorus (P) = 15

Arsenic (As) = 33

Antimony (Sb) = 51

Moscovium (Mc) = 83

02

Reaction of arsenic, bismuth and calcium

(a)

Arsenic reacts with oxygen and gets oxidized. It gives arsenic oxide as a product. The balanced equation for the reaction is as follows;

(b)

Fluorine and bismuth react with each other to form bismuth fluoride. The balanced equation for the reaction is as follows;

(c)

When calcium arsenide is hydrolyzed it gives following compound is obtained as a product.

One similarity between B and Si is the explosive combustion of their hydrides in air. Write balanced equations for the combustion ofB2H6 androle="math" localid="1653907272447" Si4H10 .

Question: As you move down Group 5A (15), the melting points of the elements increases and then decreases. Explain

Boron nitride (BN) has a structure similar to graphite, but is a white insulator rather than a black conductor. It is synthesized by heating diboron trioxide with ammonia at about 1000掳C.

(a) Write a balanced equation for the formation of BN; water forms also.

(b) Calculate 螖H掳rxnfor the production of BN (螖H掳fof BN is -254kJmol-1).

(c) Boron is obtained from the mineral borax, Na2B4O7.10H2O. How much borax is needed to produce 0.1kg of BN, assuming 72% yield?

The main reason alkali metal dihalides (MX2) do not form is the high IE2of the metal.

(a) Why is IE2 so high for alkali metals?

(b) The IE2 for Cs is 2255 kJ/mol, low enough for CsF2 to form exothermically螖H0f=-125kJ/mol . This compound cannot be synthesized, however, because CsF forms with a much greater release of heatlocalid="1663354802147" (螖H0f=-530kJ/mol). Thus, the breakdown of CsF2 to CsF happens readily. Write the equation for this breakdown, and calculate the heat of reaction per mole of CsF.
