Answer 2

A compound is a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds.
\(\bigstar\) Water is a compound, it's boiling and freezing points are fixed i.e 100°C & 0°
\(\bigstar\) Formula of water is \(\bf H_2O\) and always remains the same, this means a molecule of water has oxygen and hydrogen in a fixed ratio.
\(\bigstar\) Formula for water remains same whether it is in solid (ice), liquid (water) or gaseous (water vapors) state. There is no chemical alteration in a compound by mere change in its state
\(\bigstar\) Water can be decomposed into elemental hydrogen and water by methods like electrolysis \(\bf H_{2}O ->2H + O_{2}\)

Answer 3

So compounds can be broken into or more elements by chemical means !

Answer 4

\(\huge\color{red}\bigstar\) \(\huge\cal \color{black}{Rectification}\color{red}\bigstar\)
The correct balanced equation for decomposition of water is \(\bf 2H_{2}O->2H + O_{2}\)
