A student mixes 5.0 g of a sodium bicarbonate solution with 6.0 g of a potassium aluminum sulfate solution in a sealed container. a white, solid precipitate is formed. what is the total mass after the reaction has taken place? A. Less than 11.0 g
B. More than 11.0 g
C. Not enough information
D. 11.0g

D. 11.0g

Explanation:

The principle of mass conservation states that for a closed system (Such as a sealed container), the mass of the system will remain constant in the time. That is the mass can't be created or destroyed.

As in the experimet you are adding 5.0g of one reactant and 6.0g of another reactant, the mass of your reaction will be 11.0g although a reaction occurs in the container.

Right answer is:

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
