siniylev [52]

Answer:

the pressure (torr) of theH₂ gas is 736.2 torr

Explanation:

Given that

The H₂ gas  produced in a chemical reaction is collected through water in a eudiometer; during this process, the gas collected contains some droplets of water vapor along with these gas.

So; the total pressure in the eudiometer = Pressure in the H₂ gas  - Pressure of the water vapor

Where;

P_{Totsl} =  total pressure in the eudiometer = 760.0 torr

P_{H_2} = Pressure in the H₂ gas  = ???

P_{H_2O} = Pressure in the water vapor  = 23.8 torr

Now:

P_{Totsl} = P_{H_2} + P_{H_2O}

- P_{H_2} = + P_{H_2O} - P_{Totsl}

P_{H_2}  = - P_{H_2O} + P_{Totsl}

P_{H_2}  =  (- 23.8 + 760) torr

P_{H_2}  = 736.2 torr

Thus; the pressure (torr) of theH₂ gas is 736.2 torr

Give the correct thermochemical equations for a (cacl2+h2o) pack and (nh4no3+h2o) pack.
Umnica [9.8K]

In a pack of CaCl2 and H2O, hydrolysis of Ca+2 will occur

This will result in formation of Ca(OH)2.

The reaction is exothermic in nature

so the balanced thermo-chemical equation will be

CaCl2(aq) + H2O (l)  ---> Ca(OH)2   + 2HCl + Heat


In a pack of NH4NO3 and H2O hydrolysis of NH4+ will occur as

NH4NO3 (aq)  + H2O(l)  + Heat ---> NH4OH(aq)  + HNO3 (aq)

It is an endothermic reaction
