Answer 1

Answer:

Water (H2O)

Explanation:

The formula tells us that there are 2 Hydrogen atoms & 1 Oxygen atom present in each water molecule.The chemical formula of a co-valent network tells us the ratio of the elements present.

E.g.Silicon dioxide,(SiO2) structure.The formula tells us there are 2 silicon atoms present for every 1 oxygen atom.

Answer 2

Answer:

that is very simple but difficult question

Explanation:

first of all write the symbols of given elements
