The synthesis of barium sulfate was performed by dissolving 2.00 g of sodium sulfate in water and adding the solution to another solution prepared by dissolving 2.50 g of barium chloride in water. The
precipitate consisting of barium sulfate was filtered, washed, dried and weighed. The mass of the
precipitate was found to be 2.56 g.
Na So.(aq) + BaCl2(aq) → Baso.(s) + 2 NaCl(aq)
a) Calculate the moles of each reactant.
b) Identify the limiting reactant. Justify your selection.
c) Find the theoretical yield of barium sulfate.
d) What is the percent yield of the reaction.
e) What is the mass of the excess reactant left over after the reaction stops?

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)
