The Claus Process is an industrial process used to remove toxic hydrogen sulfide gas during the processing of crude oil. The chemical equation for this process is : 2H2S(g) + SO2(g) <> 3S(s) + 2H2O(g) + heat

Use Le Chatelier's Principle to describe why the following changes favour the removal of H2S. (a) Removing sulfur as soon as it forms (b) Cooling the reaction chamber

Use Le Chatelier's Principle to explain why the Ph of a hydrogen phosphate buffer system remains constant when (a) small amounts of acid are added (b) small amounts of base are added

Buffer solutions have the unique ability to resist changes in PH when an acid or base is added to them. One important buffer system that helps to maintain blood pH at a constant value of 7.4 is the hydrogen phosphate buffer. The chemical equation for this for this buffer system is : H2PO4(negative) (aq) + H2O (l) <>H3O (positive ...continues

conversion from square inches to cubic inches

I am trying to convert 2000 square inches into cubic inches. A simple set up showing this would be helpful.

an area-source box model for air pollution above a peninsula of land

37) Consider an area-source box model for air pollution above a peninsula of land. the length of the box is 15 km, its width is 80 km, and a radiation inversion restricts mixing to 15 m. Wind is blowing clean air into the long dimention of the box at 0.5 m/s. Between 4 and 6 pm there are 250,000 vehicles on the road, each being ...continues
