6.54. Hydrogen cyanide is used in the manufacture of clear plastics such as Lucite and Plexiglas. It is prepared from ammonia and natural gas (CHA). 2NH3(9) - 303 (9) + 2CH (9) + 2HCN(9) + 6H20(9) The reaction evolves 469 kJ of heat per mol of HCN formed. Is the reaction endothermic or exothermic? What is the value of q when 2 mol HCN forms?
Identify limiting reactants (maximum product method). Consider the reaction of methane with ammonia and oxygen. 2CH4 (g) + 2NH3(g) + 302 (g) —2HCN (g) + 6H20 (1) Determine the limiting reactant in a mixture containing 175 g of CH4, 160 g of NH3, and 607 g of O2. Calculate the maximum mass (in grams) of hydrogen cyanide, HCN, that can be produced in the reaction. The limiting reactant is: CH4 O2 NH3 Amount of HCN formed = g
Identity limiting reactants (maximum product method).
