Answer:
1.39
Explanation:
[Hg2Cl2]= 1M
[H^+] = ????
E°cell= 0.35V
E= 0.268 V
Therefore E for the reaction must -0.082 V
n= 2 moles of electrons
From Nernst Equation:
E= E°cell- 0.0592/n log [Red]/[Ox]
0.0268= 0.35- 0.0592/2 log 1/[Ox]^2
-0.082= -0.0296 log 1/[Ox]^2
log 1/[Ox]^2= 0.082/0.0296
log 1/[Ox]^2= 2.77
1/[Ox]^2=Antilog (2.77)
[Ox]^2=1.698×10^-3
[Ox] = 0.0412 M
But pH= -log [H^+]= -log(0.0412)= 1.385
Answer:
The collision theory is defined as the rate of a reaction is proportional to the rate of reactant collisions.
Explanation:
The reacting species should collide with orientation that allows contract between the atoms that will become bonds together in the product.
The collision occurs with adequate energy to permit mutual penetration of the reacting species. The two physical factors based on the orientation and energy of collision, the following reaction with carbon monoxide with oxygen is considered.
2CO(g) + O2(g) → 2CO2 (g)
After collision between the carbon monoxide and oxygen the reaction is
CO(g) + O2(g) → CO2 (g) + O(g)
Based on the theories of chemical reaction the molecules collide with sufficient amount of energy an activated complex is formed.
The number 6.022 × 1023 indicating the number of atoms or molecules in a mole of any substance
The answer is 'equal'. Hydroxide ions are OH- and Hydrogen ions are H+. Have you noticed they're opposite charges? Positive + negative = neutral. That's all there is to it :)
Answer:
I know you have been waiting awhile for this question to be answered :)
Stoichiometry is used in industry quite often to determine the amount of materials required to produce the desired amount of products in a given useful equation. Each one of these products requires stoichiometry. There would be no products from these industries without chemical stoichiometry.
Explanation:
Hopefully this helps :D
Sorry you had to wait so long :(
