Question

The elements, A with Z= 8 and B with Z= 16 are interacting each other forming an BA2 (gas) compound. The compound BA2 interacts further, under special conditions with the element with Z=8 and forms a superior oxide of Z=16. Write down the possible reactions, establish what kind of reactions are. Balance the reactions.

Answer 1

The reactants are element A with Z=8 and element B with Z=16. They form the compound
`BA_2` (gas). The compound
`BA_2` then interacts with the element with Z=8 to form a superior oxide of Z=16. The possible reactions are: A + 2B →
`BA_2` (gas) and
`BA_2` + A →
`BAO_2`. These reactions involve combination reactions, and to balance them, 2A + 4B →
`2BA_2` and
`BA_2` + A + H₂O →
`BAO_2` + H₂.

The reactants are element A with Z=8 and element B with Z=16. They form the compound
`BA_2` (gas). The compound
`BA_2` then interacts with the element with Z=8 to form a superior oxide of Z=16.

The possible reactions can be represented as:

A + 2B →
`BA_2` (gas)

`BA_2` + A →
`BAO_2`

These reactions involve combination reactions, where elements react to form a compound. The first reaction is a synthesis reaction, and the second reaction is a displacement reaction.

To balance the first reaction, we need to identify the missing components. As per the Law of Definite Proportions, if 1 gram of A reacts with 8 grams of B, then 2 grams of A must react with 16 grams of B. The balanced equation is:

2A + 4B →
`2BA_2`

In the second reaction, the oxygen atoms can be balanced by adding H₂O to one side. The balanced equation is:

`BA_2` + A + H₂O →
`BAO_2` + H₂
