Use the specific heat of water to determine how much heat is required to raise the temperature of 50.0g of water from 35oC to 55oC.
what is the percent of ethanol in the vodka, based on the concentraion od Cr^3+. PLEASE I AM so stuck! HELP this is the formula used 16H^+ + 3CH2CH2OH + 2Cr2O7^2- = 3CH3CO2H + 4Cr^3+ + 11H2O.
If the mole fraction of the ethanol in the solution is 0.65, calculate its mole fraction in the vapor phase at this tempature.The vapor pressures of ethanol and 1-propanol are 108mmhg and 40 mmg respectively.
