G An electric hot plate raises its own internal energy and the internal energy of a cup of water by 9000J, and there is at the same time 2700J transferred to the cooler air. How much energy was transferred to the hot plate in the form of electricity

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
