Answer: First subtract 32 degrees, then multiply the result by 5/9 (0.556 on a calculator). For example, suppose a thermometer reads 68 degrees Fahrenheit. Subtract 32 from 68, leaving 36. Multiply 36 by 5/9, which equals 20 degrees Celsius.

Calculate the quantity of electricity obtained from 2 moles of electrons​
Vinil7 [7]

The quantity of electricity : 2 Faraday = 193000 Coulomb

<h3>Further explanation</h3>

Given

2 moles of electrons

Required

The quantity of electricity

Solution

According to Faraday, the amount of current flowing in the electrolysis cell is closely related to the amount of substance that reacts

1 Faraday is the amount of electricity that is passed in the electrolysis cell to obtain 1 mole of electrons. 1 mole of electrons is equivalent to an electric charge of 96500 Coulombs.

The conversion / relationship can be stated as follows:

1 Faraday = 1 mole of electrons = 96500 Coulombs

1 faraday = coulomb / 96500

Can be formulated

Coulomb = Q = I. t so:

\large {\boxed {\bold {1 \: Faraday \: = \: \dfrac {i \: x \: t} {96500}}}}

so for 2 moles electrons :

= 2 x 96500 C

= 193000 C

= 2 Faraday

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>
