Name a pair of elements that would likely combine to form a salt and write the formula.

Cl and Na combine to form NaCl.

Explanation:

In neutralization reactions, an acid and a base combine to produce a salt and water. The salt forms from an anion from the acid and the cation from the base. For example:

HCl (aq) + Na(OH) (aq) -> NaCl (aq) + H2O (l)

acid            base                 salt             water

where (aq) means in aqueous medium and (l) means liquid.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
