A mixture of 33.6 g of Cr(NO3)2 and 60.5 g of CuSO4 is dissolved in sufficient water to make 98 mL of solution, where the cations react. In the reaction, copper metal is formed and each chromium ion loses one electron. How many electrons are transferred in the balanced net ionic equation with the smallest whole-number coefficients? 1. 5e-
2. 2e-
3. 7e-
4. 4e-
5. 1e-
(Part 2) What is the molar concentration of SO4^2- anions in the solution? Answer in units of M.

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.

the answer is c

tell me if wrong

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
