Consider the following chemical reaction: KClO3 →KCl + O2 If 125 g of KClO3 is heated, what is the total mass of the products?

When you perform this reaction, what could remain at the end of the reaction? check all that apply. excess reactant aqueous copper chloride excess reactant aluminum oxygen product solid copper carbon dioxide product aqueous aluminum chloride water

How do you identify the anode on a power source such as a battery? how do you identify the cathode? how are terms anion and cation?

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
