How would you prepare 75 mL of an H2SO4 solution at 20% in weight (density=1.1394 g/mL, richness=227.9 g/L) starting from the commercial H2SO4 solution (98%, density=1.8361 g/mL, richness=1799 g/L)? Please choose among the most appropriate procedure which better describes the preparation of the previous diluted H2SO4 solution: Select one or more: a. Take the required volume of commercial H2SO4 solution with an adequate pipette, pour it into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. b. Take a beaker and put about 40 mL of distilled water. Then take the required volume of commercial H2SO4 solution with an adequate pipette and pour them over the beaker. Let the solution be warm and pour the mixture into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. c. Take a beaker and put about 40 mL of distilled water. Then take the required volume…
Suppose you have a soil that is made up of 10% organic matter with CEC = 200 cmol/kg, 40% kaolinitewith CEC = 10 cmol/kg, and 50% vermiculite with CEC = 100 cmol/kg.1- Calculate the overall CEC of the soil by taking a weighted average of the three soil components.2- What percentage of the overall CEC is contributed by the organic matter? How does that numbercompare to the 10% of the soil itself that is organic?

The %purity of a powdered crude sample of Na2CO3 containing only inert impurities is to be determined by reacting 225.0 mg of the crude sample to 10.0 mL of 3.00 M HCl solution, and bubbling the resulting CO2(g) product in water that is at exactly 29 °C. After the reaction has completed, the level of the liquid inside the eudiometer rests 4.30 cm above the water level in the beaker. The graduation on the eudiometer indicates that the trapped gas is 44.37 mL. The experiment was done under a barometric pressure of 755.2 torr. a. How many moles of CO2 were collected? b. What is the percent purity of the sample? Round off to the nearest whole number
