Calculate the
Rom4ik [11]

Answer:

\large \boxed{4.7}

Explanation:

HA + H₂O ⇌ H₃O⁺ + A⁻

(a) Calculate pKₐ

\text{p}K_{\text{a}} = -\log \left (K_{\text{a}} \right ) =-\log(1.8 \times 10^{-5}) = 4.74

(b) Calculate the pH

We can use the Henderson-Hasselbalch equation to get the pH.

\begin{array}{rcl}\text{pH} & = & \text{pK}_{\text{a}} + \log \left(\dfrac{[\text{A}^{-}]}{\text{[HA]}}\right )\\\\& = &4.74 +\log \left(\dfrac{0.01}{0.01}\right )\\\\& = & 4.74 + \log1.0 \\& = & 4.74 +0.0\\& = &4.7 \\\end{array}\\\text{The pH is $\large \boxed{\textbf{4.7}}$}

The addition of chromic acid or chromate is a qualitative test for alcohols as the reaction causes a color change. However, not
Maru [420]

Answer:

3-hexanol

1 -butanol

2-pentanol

Explanation:

Let us recall that chromic acid or chromate are strong oxidizing agents. When they are oxidized, their colour changes from orange to green.

This shows a reduction in chromic acid or chromate. The reaction of chromic acid or chromate with a primary alcohol yields a carboxylic acid while reaction with a secondary substrate yields an alkanal.

Note that Tertiary alkyl halides are not be oxidized hence reactions involving a point where invitation carried along occur.

3-ethyl-3-pentanol is a tertiary alkyl halide hence it can not be oxidized.

How long would it take for a car to travel a distance of 275 km if it is traveling at a
Rainbow [258]

Answer:

5 hours

Explanation:

Given:

Distance = 275 km

Speed = 55 km/h

speed =  \frac{distance}{time}

time =  \frac{distance}{speed}

time = \frac{275}{55}

time = 5
