Answer:

The correct answer is <em>e. only slightly dissociated into ions.</em>

Explanation:

Acetic acid (CH₃COOH) is one of the best known weak acids. It dissociates into its ions as follows:

CH₃COOH (aq) ⇄ H⁺ (aq) + CH₃COO⁻ (aq)

The dissociation constant Ka is low: aproximately 1.75 x 10⁻⁵. That indicates the equilibrium is shifted to the left and the acid is only slightly dissociated into its ions (H⁺ and CH₃COO⁻).

What is the mass in 0.25 mol of SO2

gulaghasi [49]

0.25 mols SO₂ x 64.058 g SO₂/ 1 mol SO₂ = 16.0145 g SO₂

molar mass of SO₂: 64.058 g

answer: 16 grams of SO₂ (2 sig figs)

check the question to see if its asked for a specific unit for mass (grams or kilograms, if they asked for kiligrams then convert 16 grams to kilograms by dividing it by 1000)

Answer:

The $K_{m}$ of a substrate will be "10 μM".

Explanation:

The given values are:

$E_{t} = 20 \ nM$

$[Substract] = 40 \ \mu M$

$K_{cat}=600 \ s^{-1}$

Reaction velocity, $Vo=9.6 \ \mu M s^{-1}$

As we know,

⇒ $Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}$

On putting the estimated values, we get

⇒ $9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}$

⇒ $K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}$

⇒ $K_{m}+40=50$

On subtracting "40" from both sides, we get

⇒ $K_{m}+40-40=50-40$

⇒ $K_{m}=10 \ \mu M$
