From left to right: Two sets of two black balls attached to each other (4 black balls total) + two white balls attached to each other → one white ball attached to two black balls next to another white ball attached to two black balls

Answer 1

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. In other words, the total mass of the reactants must equal the total mass of the products.

Among the options you provided, the representation that best illustrates this principle is:

From left to right: Two sets of two black balls attached to each other (4 black balls total) + two white balls attached to each other → one white ball attached to two black balls next to another white ball attached to two black balls.

This option maintains the same total number of balls (4 black balls and 2 white balls) before and after the reaction, thereby representing the law of conservation of mass accurately.
