B) Ethene burns in air (combustion)
what volume of a 0.400 mM solution of nickel (II) acetate (FW 247.7 g/mol) is required to provide 20mg of nickel
Consider the situation in which 1.60 mL of an aqueous CuSO4 solution of unknown concentration is diluted to a volume of 10.00mL.
Calculate the internal energy change (deltaU) for vaporization of 100 g of Cl2(liq.) at this temperature and 1 bar? (b) Calculate its molar entropy change (AS) for vaporization at this condition
a beaker containing 250g of water is heated from 23 degrees C to 100 degrees C. what is the heat gain in calories?
