1. Some sulfuric acid is spilled on a lab bench. It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. The sodium bicarbonate reacts with sulfuric acid as follows.
2 NaHCO3(s) + H2SO4(aq) Na2SO4(aq) + 2 H2O(l) + 2 CO2(g)Sodium bicarbonate is added until the fizzing due to the formation of CO2(g) stops. If 26 mL of 6.0 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid? (g)
3. Nitrogen and oxygen gases react to form dinitrogen trioxide gas. 2 N2(g) + 3 O2(g) 2 N2O3(g)
At a certain temperature and pressure 4.2 L of N2 reacts with 6.3 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced? (L)
Show that the proton condition for a NH4Cl solution is a linear combination of the mass balance equations and the charge balance equation.
in a test on the vaporization of water into air in a wetted-wall column the following data were obtained tube diameter
Suppose the reaction Ca3(PO4)2 + 3H2SO4 ------ > 3CaSO4 + 2H3PO4 is carried out starting with 103 g of Ca3(PO4)2 and 33.7 g of H2SO4. How much phosphoric acid (H3PO4) will be produced?

Calculate the correct volume of sulfuric acid which will need to be added to neutrallize the base. The chemical reaction involves Al(OH)3 and Fe2O3 reacting with KOH and H2SO4 with the end product being KAL(SO4)2*12H2O.
ammonium hydrogen phosphate is made from reacting phosphoric acid with ammonia. if 10.00g of ammonia react, how many moles of fertilizer will be produced?
Consider the reaction N2 (g) + O2 (g) ? 2 NO (g).a. How many g NO can be produced when 25.0 g of nitrogen reacts? b. How many g NO can be produced when 25.0 g of oxygen reacts? c. Based on your answers in a and b,
A mercury manometer is connected on one side to a bulb containing argon, while the other end is open to atmospheric pressure, which is 762 mmHg.
Carbon from the most recent remains of an extinct Australian marsupial, called Diprotodon, has a specific activity of 0.61 pCi/g. Modern carbon has a specific capacity of 6.89 pCi/g. How long ago did the Diprotodon apparently become extinct? Answe..
A 15.00 mL sample of HCL solution of unknown concentration was titrated with .185 M Ca(oh)2 (aq). It took 23.9 mL of the base to reach the equivalence point of the titration.
