Answer:
b C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻
e HC₂H₃O₂ + H₂O ⇄ H₃O⁺ + C₂H₃O₂⁻
f ka<<1
g. Weak acid molecules and water molecules
Explanation:
The water molecule could act as a base and as an acid, a molecule that have this property is called as amphoteric.
b The salt NaC₂H₃O₂ is dissolved in water as Na⁺ and C₂H₃O₂⁻. The reaction of the anion with water is:
<em>C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻</em>
Where the C₂H₃O₂⁻ is the base and water is the acid.
e. The reaction of HC₂H₃O₂ (acid) with water (base), produce:
<em>HC₂H₃O₂ + H₂O ⇄ H₃O⁺ + C₂H₃O₂⁻</em>
f. As the acetic acid (HC₂H₃O₂) is a week acid, the dissociation in C₂H₃O₂⁻ is not complete, that means that <em>ka<<1</em>
g. The ka for this reaction is 1,8x10⁻⁵, that means that there are more <em>weak acid molecules</em> (HC₂H₃O₂) than conjugate base ions. Also, the <em>water molecules </em>will be in higher proportion than hydronium ions.

Explanation:
Force applied on the gas will be as follows.
As, F = pressure × area. Hence, calculate the forces as follows.
= pressure × area
= 
= 
N
= pressure × area
= 
= 
N
- = 
N
Substituting the calculated values into the above formula as follows.
= (m + M) g
N = 
N = 
m = 472.76 kg
Thus, we can conclude that the mass is 472.76 kg.
The specific heat of the metal, given the data from the question is 0.60 J/gºC
<h3>Data obtained from the question </h3>
The following data were obtained from the question:
- Mass of metal (M) = 74 g
- Temperature of metal (T) = 94 °C
- Mass of water (Mᵥᵥ) = 120 g
- Temperature of water (Tᵥᵥ) = 26.5 °C
- Equilibrium temperature (Tₑ) = 32 °C
- Specific heat capacity of the water (Cᵥᵥ) = 4.184 J/gºC
- Specific heat capacity of metal (C) =?
<h3>How to determine the specific heat capacity of the metal</h3>
The specific heat capacity of the sample of gold can be obtained as follow:
According to the law of conservation of energy, we have:
Heat loss = Heat gain
MC(T –Tₑ) = MᵥᵥC(Tₑ – Tᵥᵥ)
74 × C(94 – 32) = 120 × 4.184 (32 – 26.5)
C × 4588 = 2761.44
Divide both side by 4588
C = 2761.44 / 4588
C = 0.60 J/gºC
Thus, the specific heat capacity of the metal is 0.60 J/gºC

Answer: -
H₂ will diffuse the fastest.
Explanation: -
According to Graham's Law of Diffusion
The rate of diffusion is inversely proportional to the square root of it's density or molar mass. So the lower the molar mass faster the rate of diffusion.
Molar mass of Ne = 20 g / mol
Molar mass of CH₄ = 12 x 1 + 1 x 4 = 16 g /mol
Molar mass of Ar = 40g / mol
Molar mass of H₂ = 1 x 2 = 2 g / mol
Thus H₂ will diffuse the fastest.
