of data to recognise correlations and causal relationships Consider the water molecule‚ its properties and its physical state.

Examples include methane (CH4‚ Mr ϭ 16)‚ ammonia (NH3‚ Mr ϭ 17)‚ and carbon dioxide (CO2‚ Mr ϭ 44). But‚ unlike water‚ none of these latter molecules contains hydrogen bonds
