We can figure out the [...

Optical isomerism is a type of stereoisomerism which includes a chiral carbon. This means the pair of molecules have the same structural formula but the four different groups around the carbon atom are...

The position of equilibrium will shift to the right, favouring the forward reaction, to oppose the increase in temperature. Endothermic reactions absorb heat and therefore if the endothermic reaction i...

• down group 2 the number of protons increases therefore the nuclear charge increases (protons are found in the nucelus and have a +1 charge)

• the number of shielding electrons ...
