Description In the lab, sodium carbonate reacts with hydrochloric acid to produce sodium chloride, water and carbon dioxide. 1) Write out the formulas and balance the equation 2) What was the mass of the empty crucible and cover? 3) What was the mass of sodium carbonate used to start the experiment? 4) Using the balanced equation and the starting amount of the sodium carbonate used, calculate the expected (Theoretical) yield of sodium chloride. In other words, do a stoichiometry problem using the starting amount of sodium carbonate (recorded in question 3) to see how much sodium chloride is produced. 5) What was the mass of the crucible and cover and sodium chloride? 6) What was the actual mass of NaCl produced? 7) How does your calculation and the actual amount of NaCl produced, compare? To see, let's calculate the percent yield by using this formula: Take the actual amount of sodium chloride (answer from #6), divide it by the amount you calculated that you should get ( answer from #4) and multiply by 100. What was your percent yield? 8) Indicate any source of error in the experiment and how it could be corrected.

Description Interpreting Equations After balancing each of these equations, interpret them in terms of relative quantities in four ways. (1) number of representative particles (identify each substances as an atom, ion, formula unit or molecule), (2) number of moles, (3) masses of reactants and products (4) volumes of gases at STP (only if ALL of the substances are gases). If the equation has substances that are NOT all gases, you need to indicate that as being the reason you could NOT interpret for volume. 1) N2(g) + H2(g) ---> NH3(g) 2) K(s) + H2SO4(aq) --> K2SO4(aq) + H2(g) 3) C3H8(g) + O2(g)--> CO2(g) + H2O(g)
