Conservation of Mass Activity Description:Observe and analyze the interactions between the substances pictured in the slide show below. What observations can you make about the steel wool and oxygen in the first slide? How would you describe what they look like? How would you describe the product they make? Was mass conserved during the process (look at the sums of the masses)?Provide your observations and analysis of the beginning substances and ending substances.(Text Version of the Slide:)ReactantsSteal Wool (6 grams) + Oxygen (1 gram) = ?See the ProductIron Oxide (7 grams)ReactantsEgg (45 grams) + Heat = ?ProductCooked Egg (41 grams) + Cracked Egg Shell (4 grams)ReactantsWater (75 grams) + Heat = ?ProductSteam (75 grams gas released)ReactantsZinc (10 grams) + Hydrogen Chloride (5 grams) = ?ProductZinc Chloride (12 grams) + Hydrogen Gas (3 grams released)ReactantsSodium Hydroxide (10 grams) + Copper Sulfate (57 grams) = ?Product :Sodium Sulfate (47 grams) + Copper Hydroxide (20 grams)TitleIn this activity what would the name of the lab be? ___ObjectivesWhat was the purpose of this lab? ___HypothesisIn this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment. Use your knowledge of physical properties and chemical changes in your descriptions of your observations. DataObservations Before InteractionObservations After InteractionWas Mass Conserved?Proof of a chemical ReactionExample: Sugar + HeatThis was the at home activity in the lessonThe sugar is in tiny white particles in a pile. Heat is not seen but is implied by the heat source. The pile of sugar in the pot weighs 100 grams. There is a solid, light brown mass at the bottom of the pot. It weighs 100 grams. Yes, both the reactants and the products weigh the same. There was not a chemical reaction. Sugar did not change the composition. It only melted. Melting point is a physical property, and this is a physical change.
