Why does your finger seem to move? How is this related to the parallax of stars?
sleet_krkn [62]
<span>he easiest way to see parallax is to hold out your finger vertically in front of a background object, a door or wall for example. Shut your right eye and note where on the background object the image of your finger appears. Now open your right eye and close the left one without moving your finger. The image of your finger should appear to have jumped to a different spot on the background wall. It is possible to tell how far away your finger is from your eyes just by measuring the distance between your eyes and the distance that the image appeared to move in degrees of arc. </span>

What is the reactive intermediate in the reaction of 1,3-diene with hbr, resulting in 1,4-addition?
viktelen [127]

An allylic carbocation is a reactive intermediate in the reaction of 1,3-diene with her, resulting in 1,4-addition.

<h3>What is carbocation?</h3>
  • A molecule called a carbocation has three bonds and a positively charged carbon atom.
  • They are essentially carbon cations, to put it simply.
  • It was once referred to as carbonium ion.
  • Any even-electron cation with a sizable positive charge on the carbon atom is now referred to as a carbocation.
<h3>Why are carbohydrate molecules crucial?</h3>
  • Because charge can be exchanged between many atoms when the vacant p orbital of a carbocation overlaps with the p orbitals of another carbon-carbon double or triple bond, carbocations next to other carbon-carbon double or triple bonds are very stable.

The different unit cell types have a different packing efficiency. The simple cubic has the least efficient packing and the face
kozerog [31]

Answer:

The answer is "52.8".

Explanation:

Please find the graph file in the attachment.

They have the atoms in 8 corners with one unit cell in an one so mesh (SCC).

Atoms throughout the corner contribute \frac{1}{8}to both the cell unit

Atom number per SCC unit cell, Z = (8 \times \frac{1}{8}) = 1

Let 'r' become the atom's radius.  r = 3.43\times 10^{-8}\ \ cm

We can see from the diagram that edge length AB = a = 2r

Packing\  efficiency = \frac{(1 \ atom \ Volume  \times Z)}{Volume \ of \ unit\ cell \times  100}\\\\

                                 = \frac{\frac{4}{3}\times \pi \times r^3 \times 1}{a^3 \times 100}\\\\=\frac{\frac{4}{3}\times \pi \times r^3 \times 1}{(2r)^3 \times 100}  \\\\=\frac{\frac{4}{3}\times \pi \times( 3.43\times 10^{-8}cm)^3 \times 1}{(2\times 3.43\times 10^{-8}cm)^3 \times 100}\\\\= 52.8 \%

Enumerate any two differences between simple distillation and fractional distillation.
mr_godi [17]

Answer:

Explanation:

By simple distillation, we can separate tow miscible liquids having sufficient difference in their boiling points.

By fractional distillation, we can separate the mixture of two or more miscible liquids for which the difference in their boiling point is less than 25k

Simple distillation is done using an air condenser or water condenser.

Fractionating column is fitted in between the distillation flask and the condenser for the process.

Simple distillation eg: mixture of water and acetone

fractional distillation eg: crude oil

hope this helps
