Barrett Alosa: The law of conservation states that you cannot create or destroy matter in a chemical reaction. This means that the number of molecule "parts" (cations and anions) must be equal on both sides of the equation.
Luke Kosch: 38 B 39 A 40 A 43. stirring (stirring vs no stirring), temperature (hot tea vs cold tea), surface area (powdered sugar vs. sugar cube) 44. strange question, but i think the second one is DISPLACEMENT and the third is SUBSTITUTION. the first is impossible, because you cannot have atoms a and b morph into a and then into b. that violates the law of conservation of mass, because you are simply eliminating b and then a from your equations. ab must equal a AND b on the products side, and yet you omitted them in the given equation!...Show more
