Cr(NO3)2 and CuSO4 are dissolved in water where the compounds react. In the reaction, copper metal is formed and each chromium ion loses one electron. What is the number of electrons transferred in the balanced reaction with the smallest whole-number coefficients

In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater than 100°c the water must be permitted to evaporate quickly the system must be sealed and become pressurized above atmospheric pressure the vapor pressure must be kept below 760 mm(hg)
