Ozone reacts completely with NO, producing NO2 and O2. A 9.00 L vessel is filled with 1.00 mol of NO and 1.00 mol of O3 at 394.0 K. Find the partial pressure of each product and the total pressure in the flask at the end of the reaction.

your parents i think this could be it

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
