Skeletal structure - representation of organic compounds simply explained - substances and particles - organic chemistry. The skeletal structure represents organic compounds more clearly, simply and faster. In this context, important basic terms are line-angle formula or structural formula and valen
As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more densely packed sheds to maximise milk yields, or egg production,
