Question

Q. Make Chemical formula formulae of the following;
1)when Nitrogen chemically react with Oxygen
2)when calcium reacts with Oxygen​

Answer 1

Answer:

1.At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide. When this nitrogen monoxide is released from vehicle exhaust systems, it combines with oxygen in the air to form nitrogen dioxide. Nitrogen dioxide is a cause of acid rain .

2.When calcium metal (Ca) reacts with oxygen gas (O2), it produces the ionic compound calcium oxide (... Calcium reacts with the oxygen in the air, forming calcium oxide.
