Which explains why more energy is released in nuclear reactions than in chemical reactions? (2 points). a. chemical reactions are always endothermic.. b. no molecular bonds are broken in nuclear reactions.. c. protons and neutrons are exchanged in chemical reactions.. d. in nuclear reactions, mass is converted to energy..

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
