A normalized wavefunction for a particle confined between 0 and L in the x direction is ψ = (2/L) 1/2 sin(πx/L). Suppose that L = 10.0nm. Calculate the probability that the particle is (a) between x = 4.95nm and 5.05nm,
(b) between x = 1.95nm and 2.05nm,
(c) between x = 9.90nm and 10.00nm,
(d) between x = 5.00nm and 10.00nm.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
