What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
How many grams of NaN3 are required to produce 340 L of nitrogen gas if the gas has a density of 1.25 g/L?
How many kilojoules are needed to raise the temperature of 125 g of copper from 22 deg C to 325 deg C? My book shows copper at 0.385 j/g. Here is what I have done so far but I am not sure? 125 g x 303 deg C x 0.385 j = 14600. j 14600/1000 = Conver..
