A sample of 0.0020 mole of HCl is dissolved in water to make a 2000-mL solution. Calculate the molarity of the HCl solution, the [H3O+], and the pH. For a strong acid such as HCI, the [H3O+] is the same as the molarity of the HCl solution.
How many molecules of carbon dioxide are produced when 130 molecules of acetylene (HCCH) to react in excess oxygen produce carbon dioxide and water.
A 21.10 g sample of liquid ethanol is initially at -36.90 oC. If the sample is heated at constant pressure (P = 1 atm.), how much kJ of energy are needed to raise the temperature of the sample to 100.60 oC.
butane has a heat of vaporization of 22.44 kJ/mol and a normal boiling point of -.4 degrees Celsius. A 250 mL sealed flask contains .75 g of butane at -22 degrees C.
Calculate the theoretical yield of C2H5Cl when 139 g of C2H6 reacts with 232 g of Cl2 , assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl .
Calculate the amount of heat required to completely sublime 61.0 g of solid dry ice CO2 at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 {kJ}/{mol}.
