The given compound 3-chloro-2,2,5-trimethylhexane is an optically active compound .

Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .

It has chiral center.

Here the chiral carbon has 4 distinct groups such as : chlorine , hydrogen , 2-methylpropyl , tertbutyl .

<h3>What is di-symmetry?</h3>

Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .

<h3>Chiral center :</h3>

Have Sp3 hybridized center (4sigma bond ) .

4 distinct group is attached to the chiral atom. form non -superimposable mirror image .

<h3>What is optical isomerism ?</h3>

Same molecular formula and same structural formula . also have same physical and chemical properties .

They differ in their behavior towards plane polarized light (ppl) .

The intersection angle of a 3 degree curve is 45.2 degrees. What is the length of the curve? of Select one: O a. 455 m O b.573 m

ValentinkaMS [17]

Explanation:

Relation between length of a curve and angle is as follows.

l = $R \times \Theta$

where, R = radius of curve

$\Theta$ = angle in radians

Also, l = $R \times \Theta \times \frac{\pi}{180}$ .......... (1)

If curve has a degree of curvature $D_{a}$ for standard length s, then

R = $\frac{s}{D_{a}} \times \frac{180}{\pi}$ ........... (2)

Now, substitute the value of R from equation (2) into equation (1) as follows.

l = $\frac{s \times \Theta}{D_{a}}$

If s = 30 m, then calculate the value of l as follows.

l = $\frac{s \times \Theta}{D_{a}}$

= $30 \times \frac{45.2}{3}$

= 452 m

thus, we can conclude that the length of the curve is 452 m.

For the balanced chemical reaction

musickatia [10]

Answer:

150

Explanation:

C₄H₂OH + 6O2 → 4CO2 + 5H₂O

We can <u>find the equivalent number of O₂ molecules for 100 molecules of CO₂</u> using a <em>conversion factor containing the stoichiometric coefficients of the balanced reaction</em>, as follows:

100 molecules CO₂ * $\frac{6moleculesO_2}{4moleculesCO_2}$ = 150 molecules O₂

150 molecules of O₂ would produce 100 molecules of CO₂.

the temperature of a sample of water increases from 20celsius to 46.6celsius as it absorbs 5650 J of heat. what is the mass of t

Levart [38]

Answer:

m = 50.74 kg

Explanation:

We have,

Initial temperature of water is 20 degrees Celsius

Final temperature of water is 46.6 degrees Celsius

Heat absorbed is 5650 J

It is required to find the mass of the sample. The heat absorbed is given by the formula ad follows :

$Q=mc\Delta T$

c is specific heat of water, c = 4.186 J/g°C

So,

$m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{5650}{4.186\times (46.6-20)}\\\\m=50.74\ kg$

So, the mass of the sample is 50.74 kg.
