Question

Experiment 2: Perform a Decomposition Reaction Data Analysis 1. What was the change in mass of the contents in the crucible? Compare the mass after heating to the mass before heating It 5.00g then after heated it decreased by 1.673g to 3.327g 2. The color change of the of copper compounds to identify the product. Cucos light green powder Cu(OH)2 blue green powder Cu20 reddish brown crystals CuO black powder CuCo3 changed to Cuo 3. Given that mass was lost from the copper (l) carbonate hydroxide hydrate during heating, in this decomposition reaction, how many moles of solid product were produced? The molar mass of the solid product is 79.545 g/mol (number of moles mass (g) /molar mass 0.0418 4, Copper carbonate hydrate produces 1 mole of water (MM m 18.015 g/mol) for every mole of solid product (MM 79.545 g/mol) produced, Given that 3.327 solid product were produced during the reaction, how many grams of water were released as water vapor? number of moles, mass (gW molar mass (g/mol) 0.093
