What is one main difference between nuclear fission, nuclear fusion, and nuclear decay? A. Nuclear decay occurs spontaneously as a random event. B. Nuclear decay is initiated by adding a large amount of energy. C. Neutrons are only present in nuclear fission reactions. D. Smaller nuclei are produced following nuclear fusion.

How can you use chemical equations to predict the products of the reaction you can carry out?

Consider the elements bromine and chlorine; which elements has a larger ionic radius ?

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
