Question

Write two chemical formulae showing the steps involved when a metal combined with a radical.

Answer 1

Answer:

The answer is Na2CO3 and K2SO4.

Explanation:

A radical is a group of atoms that have some charge on it.  

For example carbonate CO32-, sulfate SO42-, sulfite SO32-, nitride N3- and phosphate PO43- all are an example of radicals.

Following are two examples in which a metal combines with a radical to form salts.

1- When sodium combines with carbonate CO32- radical it forms sodium carbonate Na2CO3.

2- When potassium combines with sulfate SO42- radical it forms potassium sulfate K2SO4.
