NAME ___________________________________________ BLOCK ________________________________ DO NOW 1. Magnesium (Mg) strips are long, thin strips that are grey and shiny. Which action will lead to a chemical change of magnesium strips? a. Burning them with a candle c. Mixing them with pieces of copper (Cu) b. Cutting them into small pieces 2. Does the following chemical equation following the Law of Conservation of Mass? 4H + O2 2H2O a. Yes, because there are 4 hydrogen atoms in the reactants and products. b. Yes, because a compound is present on both sides of the equation. c. No, because mass was created in the products. 3. Bird wings and insect wings are analogous structures. Which can most likely be concluded? a. Insects evolved from birds. c. Birds and insects share a common ancestor. b. Birds evolved from insects. d. Birds and insects are completely unrelated. 4.
