48 For an investigation a student poured a blue solution of Cuso, into a beaker. The student placed a shiny, silver-colored strip of zinc metal in the solution and observed the changes. Observations of an Investigation Zn Cuso, ZnSO4 Blue solution Zinc in blue solution Zinc in clear solution The student inferred that a chemical reaction occurred. What evidence supports this inference? F A dark solid formed on the zinc metal. G The zinc metal remained silver-colored and shiny. H The Cuso, solution turned blue when the zinc metal was added. None of these

i'm pretty sure its b i might be wrong though!

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
