A solution with a Ph of 2 has a H+ ion concentration that is two times greater than a solution with a ph of 4. The Ph of 2 and 4 indicate that the solution is acidic since they are less than PH of 7. The H+ ions are more present when the solution is acidic but the Ph differ with concentration H+ ions. The solution with a Ph of 2 has more H+ than the solution with Ph of 4 thus the solution with Ph of 2 has more hydrogen ions than that of 4
In this reaction
ester is reduced to
aldehyde. Such reduction can not be achieved by reacting reducing agents like
LiAlH₄ because it will further reduce aldehydes to alcohols. So, in order to stop reduction at alddehyde, ester is reacted with bulky reducing agent, <span>
Diisobutylaluminium hydride (DIBAL) which works with same mechanism as that LiAlH</span>₄ do. It also add hydride to carbonyl group. The reaction is shown below,
Answer:
Argon 7.89693x10^25 atoms
Gold 4.1949252x10^25 atoms
Carbon Monoxide 34.55149 moles
Potassium oxide 1.6 moles
Calcium 4.4969x10^24 atoms
Explanation:
Its done with dimensional analysis i can not put the full work here because it would look to sloppy
Answer:
Opion 4. The hydrogen in HCl reduce from proton to hydrogen gas (H at ground state)
Explanation:
The reaction is: Mn + HCl → MnCl₂ + H₂
Magnessium changed the oxidation state from 0 to +2
It has increased, so it was oxidized
H changed the oxidation state from +1 to 0
It has decreased, so it was reducted.
