Question

12g of baking soda and 7g of vinegar are mixed together in a sealed container whose mass is 25g. After the reaction has completed, what will the combined mass of the container and products be?
A.37g
B.19g
C.less than 19g
D.44g

Answer 1

Answer:

d. is the correct answer bro.

Answer 2

The answer is option D) 44g

Explanation:

The mass of baking soda $= 12 g$

The mass of vinegar $= 7g$

• Thus, the total mass of reactants $= 12 + 7 = 19 g$

The mass of the container $= 25 g$

• The combined mass of container and reactant $= 19 + 25 = 44g$

Thus, according to the law of conservation of mass, "the mass of reactant will be equal to the mass of the product".

• Hence, the mass of product $= 19 g$

And the mass of the container remains the same $= 25 g$

Thus,

the combined mass of the container and products $= 19 + 25 = 44g$
