Reactions (16 pts) consider two beakers. in beaker #1, 123.0 g of barium nitrate is dissolved in 500 ml of water. in beaker #2, 123.0 g of potassium sulfate is dissolved in 500 ml of water. the two solutions are poured into a common vessel, and 109.8 grams of solid barium sulfate form. the remaining material stays dissolved in the water.
a) write and balance chemical equation for this process. be sure to include subscripts that indicate the state of matter. (4 pts)
b) what was the molar concentration of barium nitrate in beaker #1? (4 pts)
c) which is the limiting reagent for this reaction? show how you determined this. (4 pts)
d) what is the molar concentration of the excess reagent in the reaction vessel after the reaction? (6 pts)

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
