This analogy of a dance representing chemical reactions can help make understanding reactions easier, but it does not represent actual chemical reactions. List three examples of actual chemical reactions and for each example explain how the reaction can be manipulated to increase the reaction rate.

In general metals get as you move from left to right across the periodic table.

Why is it important for scientists to review and repeat the work of other scientists? 1.a scientific theory must be tested three times before it is proven. 2.the scientific method only applies to repeated experiments. 3.an experiment may have had errors that the scientists didn't recognize. 4.the results of individual scientists may be influenced by bias. 5.an experiment must be performed twice before the data can be analyzed.

It takes 155. kj/mol to break a fluorine-fluorine single bond. calculate the maximum wavelength of light for which a flouine-flouring single bond could be broken by absorbing a single photon
