Question

a student draws a picture of the products and reactants of a chemical reaction. what, if anything, is wrong with the drawing? a the drawing is wrong because there are more chemicals on the products side. b the drawing is correct because there are 12 compounds on each side of the arrow. c the drawing is wrong because there are different compounds on each side of the arrow. d the drawing is correct because there are 12 atoms of each type on each side of the arrow.

Explanation:

In a chemical reaction, the law of conservation of mass states that the number of atoms of each type must be the same on both the reactant and product sides. By counting the atoms of each type in the drawing, we can check if this law is obeyed.

Answer:

D. The drawing is correct because there are 12 atoms of each type on each side of the arrow.
