At what temperature does water boil at 101kPa?

100°C

Explanation:

A liquid boils when the vapour pressure is the same as the atmospheric pressure. At 101kPa or 1 atm, water boils at the well known number of 100°C. If  the pressure is different, you will have to use the Clausius Clapeyron Equation.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
