Answer:
See explaination
Explanation:
methyl-3-nitrobenzoate = 3-NO2-C6H4-COOCH3
Singlet at 4 ppm = CH3 from ester (COOCH3)
Triplet at 7.6 ppm = Aromatic, H5 proton
Doublet at 8.2 ppm - Aromatic, H4 and H6 protons
Singlet at 8.8 ppm - Aromatic, H2 proton
See attached file for diagrammatic representation and further solution.
Explanation:
Neutralization reaction is a type of chemical reaction in which an acid and a base react together to form a salt <u><em>and water</em> </u>as products.
i believe that momentum is the answer :)
Answer is: pH of methylamine is 12,2.
Chemical reaction: CH₃NH₂(aq)+ H₂O(l) ⇌ CH₃NH₃⁺(aq) + OH⁻<span>(aq).
Kb(</span>CH₃NH₂) = 4,4·10⁻⁴.
c₀(CH₃NH₂) =
0,57 M.
c(CH₃NH₃⁺) = c(OH⁻) =
x.
c(NH₂OH) = 0,57 M - x.
Kb
= c(CH₃NH₃⁺) · c(OH⁻) / c(CH₃NH₂).
0,00044 = x² / (0,57 M - x).
Solve
quadratic equation: x = c(OH⁻) =
0,0156 mol/L.
pOH
= -log(0,0156 mol/L.) = 1,80.
pH
= 14 - 1,80 = 12,2.
I think Kinetic energy forms <em>Motion energy </em>and Potential energy forms <em>Gravitational Potential energy.</em>
