A 0.070-g sample of the boron hydride, , is burned in pure oxygen to give and . Calculate the pressure of the gaseous water in a 5.05-L flask at 40. °C. Pressure = mmHg

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.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

the answer to your question is c
