How does the oxidation state of na change in the following reaction?
li(s) + naoh(aq) → lioh(aq) + na(s)

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

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
