Empirical formula of a compound is a formula that shows the simplest whole number ratio between the atoms of the elements in the compound. It can be calculated from the percentage composition of the elements present in a compound. The various steps involved in determining the empirical formula are:..

Radiocarbon The 1 4 C so produced is eventually converted into CO 2 , which in turn is incorporated into plants and trees by the process of photosynthesis and then finds way into animals, which eat plants. As there is a natural plant-animal cycle, an equilibrium is set up and all living matter cont..
