Question

A student measures out 5 mL of calcium chloride solution into a small container and 5 mL of sodium carbonate solution in another small container. The total mass of both chemicals and the containers they are in is 15.5 g. When the student combined the two clear liquids, a gooey, cloudy precipitate formed. What would the total mass of the products and the two containers be after this reaction took place?

    Answer:

    15.5

    Explanation:

    in a chemical reaction, mass is conserved

    so mass after reaction = mass before reaction = 15.5 g

    Answer:

    15.5g

    Explanation:

    “The total mass of both chemicals and the containers they are in is 15.5 g.” After a chemical reaction, by conservation of mass, the total mass of the products and the two containers after reaction is the same at 15.5g.
