What is the theoretical yield of CC14 for a reaction using 80 g C12? If the actual yield from the reaction is 38 g of CCI4, what is the percent yield of CC14? Step 1 gram to gram Step 2 PY= (Actual/Theoretical) x 100. Molar Mass of Ch2= 70 g/mol, Molar mass of CC14= 152 g/mol C + 2C12--> CC14

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
