Low pressure is the correct answer.
Answer:
where is it?
Explanation:
please write down the solution
The Bohr Model, which was proposed by Niels Bohr in 1913
Below is the list of enthalpies of formation of the compounds involved in the chemical reaction.
HCl: -92.3 kJ/mol
H2: 0
Cl2: 0
Both H2 and Cl2 do not have enthaply of formation because they are pure substances.
Since, in the reaction there are 2 moles of HCl,
Enthalphy of formation = enthalpy of products - enthalphy of reactant/s
= 0 - (-92.3)(2) = +184.6 kJ
Hence, the answer is the first choice.
Answer:
The answer to your question is: [H+] = 0.0016
Explanation:
Data
pH = 2.8
[H+] of the solution = ?
Formula
pH = -log [H+]
process
2.8 = -log [H+] then we get antilog
antilog (-2.8 ) = [H+]
[H+] = 0.0016
