A student performs a reaction to precipitate copper (II) carbonate from copper (II) acetate and sodium carbonate. The theoretical yield for this experiment is 4.98 g. The reaction performed by the student yielded 2.03 g. What is the percent yield?

Total the mass on the syringe. record it in the correct row of the data table. kg done click and drag weights to change the pressure. click the syringe to zoom in and see the volume. intro

How is the way a mixture is combined different from how a compound is combined?

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
