Pls conservation of mass activity worksheet instructions: observe and analyze the interactions between the substances pictured in the slide show. compare the properties of substances before and after each interaction. you will submit your completed worksheet for grading. data table on the table below, record your observations before and after the interactions and note if mass was conserved. describe the changes in properties that prove a chemical reaction occurred. the first row is an example. observations before interaction observations after interaction was mass conserved? proof of a chemical reaction example: sugar + heat the 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 composition. it only melted. melting point is a physical property, and this is a physical change. steel wool + oxygen (fire)= egg + heat= water + heat= zinc + hydrogen chloride sodium hydroxide + copper sulfate=
