Calculate the heat energy released when 14.1 g of liquid mercury at 25.00 C is converted to solid mercury at its melting point.
Constants for mercury at 1 atm:
Heat capacity of Hg (l) 28.0 J/(mol K)
Melting point 234.32 K
Enthalpy of fusion 2.29 kJ/mol
Calculate the pressure of the gas mixture and the partial pressure of each constituent gas if the mixture is in a 11.0 L vessel at 27 degree celsius
What is the theoretical yield of bismuth when 393 g of Bi2O3 reacts with excess carbon as shown below? Bi2O3 + C(s) => Bi(s) + CO(g) (not balanced)
In a second experiment, I(electric current) broke down a sample of H 2 O into 1.45 grams of hydrogen and 11.51 grams oxygen. Are these results reliable with the law of exact extent?
Three isotopes of argon occur in nature - 36Ar, 38Ar, 40Ar. Calculate the average atomic mass of argon to two decimal places, given the following relative atomic masses and the abundances of each of the isotopes: argon

If a bottle of nail polish remover contains 176 mL of acetone, how much heat would be released by its complete combustion? The density of acetone is 0.788g/mL.
You have given some solutions as A. O.6MNH3 b. 0.150MKOH c. 0.100M Ba(OH)2 you just need to determine that which of the given solution is the most basic also give explanation for your answer?
The reactant concentration in a first-order reaction was 6.70×10-2 after 25.0 and 3.30×10-3 after 100 . What is the rate constant for this reaction?
enzyme1 (E1) is required to convert reactant B to product C. Enzyme 2 (E2) is required for the reverse reaction (C to B). The activity of E1 is 50 pmol of C created/10^6 cells *s and that of E2 is 40 pmol of B created/10^6 cells*s.
