My undergrad researchers are trying to approximate the binding potential energy landscape for ti and are using an lj potential. they claim to reproduce experimental data for the metallic equilibrium radii for ti with an e value of 0.4ev and a σ of 1.3˚a? did my undergrads correctly approximate the equilibrium distance between ti atoms? what is the energy at the equilibrium distance in joules? according to this potential at what distance is the force maximized? should they publish the results using this potential?

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.
