Based on the following chemical equation: 4HCN 5O2 2N2 4CO2 2H2O. Identify the limiting reactant and the mass of N2 produced when 100. g of HCN react with 100. g of O2. g

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

answersilicon (si); oxygen (o);

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.
