" In industry, sodium carbonate is produced in two stages whose equations are as follows: NaCl + NH3 + H2O + CO2 NH4Cl + NaHCO3 2NaHCO3 + heat Na2CO3 + CO2 + H2O a)What s the mass of sodium carbonate that can be produced from 1.0 t of sodium chloride? (Assume that the...
when 3.20 g of a molecular solute were dissolved in 60.0 g of water at 50 C, the vapor pressure of the resulting solution was found to be .120 atm.(the vapor pressure of pure water at 50 is 0.122 atm)
i need help on all of them. the graphs are on the bottom.
Anyone have the free file of An introduction to chemical engineering kinetics and reactor design Charles G. Hill solutions manual?
A solution is prepared by dissolving 12.1 g ammonium sulfate in enough water to make 131.0 mL of stock solution. A 13.40 mL sample of this stock solution is added to 56.20 mL of water. Calculate the concentration of ammonium ions and sulfate ions in the final solution.

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
- 1. For organic chemistry, what is a concerted shift? How do things like acids or heat affect them? What other factors affect them?
2. Which of the following reactions is an acid-base neutralization reaction? Why are the rest of the answers incorrect?
- A. AgNo3 (aq) + NaI (aq) --> AgI (s) + NaNO3 (aq)
- B. S8(s) + 8O2 (g) --> 8SO2(g)
- C. Na3PO4 (s) + 2H2O (l) --> H2 (g) + 2NaOH (aq)
- D. Ca (OH)2 (aq) + 2HI (aq) --> CaI2(aq) + 2H2O (l)
