A rain water analysis gives 3.14mg/L sulfate (SO42-) and 1.93mg/L nitrate as (NO3-). Assuming that all of the sulfate and nitrate originated as acids. calculate the expected pH of this rain water.
How many grams Na3PO4 of will be needed to produce 475 mL of a solution that has a concentration of Na+ ions of 0.900 M ?
the tip of a vinegar buret but disappears during the course of the titration, how would this affect your calculation of the concentration of acetic acid
If a reaction mixture contains only N2O and NO2 at partial pressures of 1.0 atm each, the reaction will be spontaneous until some NO forms in the mixture.
An Ideal Gas: What makes it so? Molar mass defined A Unified Gas Law: Application to problem solving What about non-ideal (or real) gases?
Determine How much sodium hydroxide (in grams) is required to form 546 mL of solution with a pH of 10.00?
Determine the mass of aluminum acetate that can be made if you do the reaction with 125 grams of acetic acid and 275 grams of aluminum hydroxide.
A catalyst decreases the activation energy of a particular exothermic reaction by 59 kJ/mol, to 51 kJ/mol. Assuming that the mechanism has only one step, and that the products are 94 kJ lower in energy than the reactants
Critically evaluate your evidence on whether the limonene isolated from orange peels
Chlorine trifluoride is used in processing nuclear reactor fuel. It has a vapor pressure of 29.1 torr at -47.0°C and its heat of vaporization is 30.61 kJ/mol.
We add excess Na2CrO4 solution to 17.0 mL of a solution of silver nitrate (AgNO3) to form insoluble solid Ag2CrO4. When it has been dried and weighed, the mass of Ag2CrO4 is found to be 0.310 grams.
CaC2 (s) + 2H2O (l) → C2H2 (g) + Ca(OH)2 (aq) If 32.0 g CaC2 are consumed in this reaction, how many moles of H2O are needed?
