3. The Contact process consists of three stages. Stage 1: The production of sulphur dioxide This can be obtained by two methods: 1. Burning of sulphur in dry air in the furnace S + O SO2 2. Burning of metal sulphide such as zinc sulphide or iron(III) sulphide in dry air. 2ZnS + 3O2 2SO2 + 2ZnO Stage 2: Formation of sulphur trioxide In the converter‚ sulphur dioxide and excess oxygen gas are passed over a few plates of vanadium (V) oxide‚ V2O‚ the catalyst at 450°C to produce sulphur trioxide

OXIDATION AND REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where

On January 16‚ 2016‚ President Barack Obama declared the city of Flint‚ Michigan to be in a state of emergency due to the widespread lead poisoning of the city’s residents that later became known as the Flint Water Crisis (Southall 2016). The crisis began in April of 2014‚ when the officials of Flint decided that‚ in an effort to conserve dwindling funds‚ the city would switch their main water source from Lake Huron‚ to the Flint River (Southall 2016). Almost immediately‚ the residents of Flint began
