if you have water of 330 ml at 25 degrees and then combine water of 130 ml at 95 degrees Celsius temperature, then determine the final temperature of the mixture. (Use 1g/mL as the density of water)
if 0.10M aqueous solutions are prepared of each of the following acids, which produces the solution with the lowest pH?
Compute the molality of a solution containing 327 g glucose(C6H12O6) dissolved in 1.52 L of water. (Assume a density of 1.00 g/mL for water.)
The following choices list some common laboratory solvents. In which of these solvents would LiCl be the LEAST soluble
what volume of 420 ml of hydrogen occupy if the temperature is raised from 0 C to 95 C?
Determining System Equilibrium, A one-litre cylinder at 458'C is found to contain 0.36 moles of HI (g), 0.15 moles of I 2(g), and 0.18 moles of H2(g). Is this system at equilibrium?
A quantity of ice at 0°C is added to 66.4 g of water in a glass at 55°C. After the ice melted, the temperature of the water in the glass was 15°C. How much ice was added? The heat of fusion of water is 6.01 kJ/mol and the specific heat is 4.18 J/(..
Magnesium oxide reacts slowly with water to form magnesium hydroxide. What would be the effect on the observed value for ∆H_rxn for the reaction of MgO if 10%
The Wittig reaction involves coupling between a phosphonium ylide and a carbonyl-containing molecule. If a chemist wants to use the Wittig reaction to synthesize 3-methyl-3-hexene, which reactants should be used
The total mass of solid unknown dissolved in the sample was 0.1200 g. If the sample were dissolved to a final volume of 100.0 mL, and a 25.00 mL sample of the solution required 36.32 mL of EDTA solution, find the mass percent of CaCO3 that was pre..
