Asealed glass jar has a small amount of water on the bottom. the rest of the volume in the jar is taken up by helium gas at a partial pressure of 526 mmhg, and water vapor. if the total pressure inside the jar is 760. mmhg, what is the temperature of the water?

The temperature of the water is 70°C

Explanation:

Partial pressure of helium gas = 526 mmHg

Total pressure inside the jar= 760 mmHg

Suppose partial pressure of helium gas is and partial pressure of water is

And total pressure is

As we know

Hence

Putting the values  

In bar,

= 0.312 bar

 Now according to the steam table  

With the vapour pressure of water as 0.312 bar the temperature corresponds to 70°C

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).
