Question

this section is very confusing as a whole

What compound can be dissolved into an aqueous solution of barium chloride that will precipitate the barium ions out of the solution? There are many correct answers. You must write only one. 4 Nitrogen monoxide gas reacts with hydrogen gas to form ammonia and water gases. How many grams of hydrogen are needed to make 6.22 g of NH3(g)? Show all work and units. 8 25.1 mL of a 1.19 M aqueous aluminum sulfate is mixed with 80.00 mL of 2.0 M aqueous silver nitrate. a. Calculate the theoretical yield of the precipitate in grams. b. Calculate the molarity of all ions left in solution after the reaction. 6
