Answer:
The Milky Way is a large barred spiral galaxy
Explanation: that has more than etc
a) Ka for benzoic acid, C6H5CO2H <span>
HA + H2O ⇋ A^-
+ H3O^+ </span><span>
Ka = [A^-][H3O^+] / [HA]
C6H5CO2H + H2O ⇋
C6H5CO2^-^- + H3O^+ </span><span>
Ka = [C6H5CO2^-][H3O^+] / [C6H5CO2H] </span>
<span>
b) Kb for benzoate ion, (C6H3CO2)^ -
B + H2O ⇋
[BH]^+ + OH^- </span><span>
Kb = [[BH]^+][OH^-] / [B]
C6H3CO2^- + H2O ⇋
C6H5CO2H + OH^- </span><span>
Kb = [C6H5CO2H][OH^-] / [C6H3CO2^-] </span>
<span>
c) Kb for amiline, C6H5NH2 amiline? aniline
C6H5NH2 + H2O ⇋
[C6H5NH3]^+ + OH^- </span><span>
Kb = [[C6H5NH3]^+][OH^-] / [C6H5NH2] </span>
<span>
d)Ka for amilimium ion, (C6H5NH3)^+
C6H5NH3^+ + H2O ⇋
C6H5NH2 + H3O^+ </span><span>
<span>Ka = [C6H5NH2][H3O^+] / [C6H5NH3^+]</span></span>
Answer:
A
Explanation:
Cs has a higher rate of reaction because it's easier to remove an electron from it, thereby leading to faster reactivity
Answer:
The activation energy is 7.11 × 10⁴ J/mol.
Explanation:
Let's consider the Arrhenius equation.
where,
k is the rate constant
A is a collision factor
Ea is the activation energy
R is the ideal gas constant
T is the absolute temperature
The plot of ln k vs 1/T is a straight line with lnA as intercept and -Ea/R as slope. Then,
Question options:
1. Insoluble
2. Soluble
3. Solvable
Answer:
Soluble
Explanation:
The solubility is a chemical property referring to the ability of the solute to dissolve in a solvent and form a homogeneous mixture (solution). It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium.
<u>Therefore, a substance is soluble in a particular liquid if it is able to dissolve in a solvent.</u>
