Calculate the numbers of subatomic particles and the electronic configurations for the following ions 4Ca20*, 33S16 and 39C117. Comment briefly on the importance of pH measurements in chemical sciences. The pH of seawater is 8.30. Calculate the [H3O"] and [OH] ion concentrations. Discuss the chemistry of the CC functional group with an emphasis on the sp hybridisation at the carbon atom. Describe a reaction involving this triple bond. water, HO, is often referred to as the molecule of life. Describe the bonding in HO. The O-H (sigma) bonds in HO can be described as polar covalent. How does this account for the hydrogen bonding properties of water? Explain the scientific terms Osmosis and Dialysis with the aid of relevant diagrams.
