A sample of 8.51 g of solid calcium hydroxide is added to 35.0 mL of 0.480 M aqueous hydrochloric acid. Write the balanced chemical equation for the reaction. Physical states are optional. chemical equation: What is the limiting reactant? hydrochloric acid calcium hydroxide How many grams of salt are formed after the reaction is complete? mass of salt: How many grams of the excess reactant remain after the reaction is complete? excess reactant remaining: g

A sodium sulfate solution is added to a 25.0 mL sample of a solution containing Ba2+ ions until no more precipitate formed.  The precipitate (BaSO4) is collected, dried, and weighed.  If 1.59 g of the precipitate are obtained, what is the concentration (in M) of Ba2+ ions in the 25.0 mL sample? Your answer should have 3 sig. figs. Molar Masses:  (Na2SO4: 142.05 g/mol)  (Ba2+: 137.3 g/mol) (BaSO4: 233.37 g/mol)
