Consider the balanced equation for the following reaction:
2H3PO4(aq) + Al2(CO3)3(s) → 3CO2(g) + 3H2O(l) + 2AlPO4(s)
If 50.9 grams of H3PO4 reacts with 80.3 grams of Al2(CO3)3, which species is the limiting reagent in the reaction
Phosphate systems form essential buffers in organisms. Calculate the pH of a buffer made by dissolving 0.80mol of NaOH in 0.50L of 1.0M H3PO4.
The fermentation of glucose (C6H12O6) produces ethyl alcohol (C2H5OH) and CO2: C6H12O6(aq) → 2 C2H5OH(aq) + 2 CO2(g)
vinger contains 5.0 g of acetic acid, CH3COOH,in 100.0 mL of solution. Calculate the molarity of acetic acid vinegar?
A BaSO4 slurry is ingested just before the gastrointestinal tract is x-rayed because it is opaque to x-rays and defines the contours of the tract. Ba2+ ion is toxic, but the compound is nearly insoluble
Consider the reaction: 2SO2(g)+O2(g)?2SO3(g) What changes will occur in the concentration of SO2,O2, and SO3 at equilibrium if we were to: a. increase temperature b. increase pressure c. increase SO2 d. add a catalyst e. add helium at constant pre..
