2. at o°c, air can contain
4.85 g/m² of water vapor.
assume the actual water
vapor content is 0.97 g/m3.
what is the rh?

RH = 20%

Explanation:

Data given:

water pressure at 0°C  = 4.85 g/m³

Actual water vapor density = 0.97 g/m³

Relative humidity (RH) = ?

Solution:

Formula used

       Relative humidity (RH) =    x 100%

As we know that at 0°C water vapor have 4.85 g/m³ saturated vapor density.

So,

put values in the above formula

     Relative humidity (RH) =  0.97 g/m³ /  4.85 g/m³ x 100%

     Relative humidity (RH) =  0.2 x 100%

     Relative humidity (RH) = 20%

So,  

Relative humidity (RH) = 20%

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 is true. hope it .
