Calculate what quantity of potassium chlorate that has molecular weight of 122.5 needed to form 33.6 litres of oxygen? Express your answer in grams and assume that temperature and pressue will be in normal condition?
Write the chemical equation for the formation of HBr from H and Br atoms. Lone pairs do not need to be included. Using the table of bond energies determine the ?H for the above reaction. (KJ/Mol)
A solution contains one or more of the following ions: Pb 2+, Ca 2+, and Zn 2+. When sodium chloride is added to the solution, a precipitate forms
If you look at a reaction for an esterification reaction, you cannot tell where the oxygen comes from (acid or alcohol). Draw the mechanism of this reaction, and devise an experiment using the mechanism and O18 (O18 isotope) to help prove unequivo..
