Lab #5 Chemical Reactions & Balancing Equations Objectives Observe and classify several chemical and physical changes. Give evidence for the occurrence of a chemical reaction. Write a balanced equation for a chemical reaction. Identify a reaction as a combination‚ decomposition‚ replacement‚ or combustion reaction. Background Physical properties can be observed without changing the chemical composition of the substance. Common physical properties that can be measured without changing the chemical

Benedict ’s solution contains Cu+2 ions that are blue in colour. This means that when Benedict ’s solution is added to clear transparent or translucent solutions‚ the solutions turn light blue due to the presence of the Cu+2 ions. Out of the 12 solutions‚ solution 10 (beer) was a light brown-yellow colour‚ while the remaining 11 were either transparent or translucent. Thus‚

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances
