At the start of an experiment, there are 0.200 mol of reactant and 0 mol of product in the reaction vessel. After 25 min , 0.106 mol of reactant (CH3NC) remain. There are ________ mol of product (CH3CN) in the reaction vessel
Identify the factors that affect toxicity in a population. Pick three of the factors and provide a brief discussion on how that factor can affect the health of a population.
Suppose an unknown hydrate, AC*XH2O, has a mass of 1.555g before heating, and a mass of .994g after heating, Define what is the experimental percentage of water in the hydrate
Problem- Calculate the difference between the change in enthalpy and the change in internal energy when 1.00 kg of gaseous methanol is oxidized to gaseous CO2 and H2O at 65 degrees Celsius. Assume ideal gas behavior.
