A solution is prepared by mixing 5.00 g of compound Z (molar mass 15.00 g/mol) in 100.0 ml of water. The density of the solution is 1.09 g/ml. Calculate the molarity of the solution.
How many moles of a metal chloride (MCl2) will dissolve in 2.0 liters of 0.050 M NaCl solution. (Ksp for MCl2 = 1.24 x 1-^-10)
At high temperature, ammonia reduces copper(II) oxide to the free metal: Step 1: 2NH3(g) + 6CuO(s) => N2(g) + 3Cu2O(s) + 3H2O(g)
Does your spectrum allow you to confirm that the structure of the product is a combination of the two reactants. Briefly explain.
Consider the reaction 5Br^- (aq) + BrO3^-(aq)+ 6H^+(aq) ---> 3Br2(aq) + 3H2O(l) The average rate of consumption of Br^- is 1.15×10^?4 M/s over the first two minutes. What is the average rate of formation of Br2 during the same time interval
Determine the partial pressures of each of the reactants CH4 O2 NO in the flask and the partial pressures and of each of the products and the total pressure in the flask
CO2 has a mol wt of 44 Da. 5.0 micro liters of CO2 is added to 525 mL of air. The pm of CO2 by volume and weight is/are?
The selection of enantiomerically pure (1S)-[endo]-(-)-borneol in the upcoming experiment presents a great opportunity to review some stereochemistry basics
The value of Kf for cyclohexane is 20.0°C/m, and its normal freezing point is 6.6°C. A mass of 1.604 g of a waxy solid dissolved in 10.000 g of cyclohexane results in a freezing point of 4.4°C. Calculate the molar mass of the solid.
Write out all equations (but you do not have to do the integration!) how you would calculate the absolute entropy of Cl2(g) at 298K. For full credit, you must include the limits of integration.
If you add a solvent called "dioxane" to water, a homogenous mixture forms. Dioxane and water have the same boiling point (100oC). How do you explain that the mixture of the two compounds shows a boiling point that is lower than the one found for ..
Calculate the pH of a solution formed by mixing 100.0 mL of 0.20 M HClO with 200.0 mL of 0.30 M KClO. The Ka for HClO is 2.9 × 10-8.
72 ml of a 1.70 m solution is diluted to a volume of 288 ml.a 144 ml portion of that solution is diluted using 149 ml
