Calculate sound speed in hydrogen H2 at temperture 50 C degree. Answer give in meter per second.
1 answer:
Answer:
The speed of sound in hydrogen gas is 361.5
Explanation:
It is given that the temperature is 50 .
The speed of sound in meter per second is calculated by an equation.
The equation states that speed of the sound in meter per second is equal to the sum of the product of the temperature in degree celsius with 0.60 and a constant that is 331.5.
The equation is written as:
Put the value of T = 50 then the equation becomes,
Speed of sound (in m/s) = 361.5 m/s

Explanation:
The equation is already balanced and it is a double replacement reaction.
Polarity is induced in the molecules when there are significant electronegativity differences between its atoms. Due to this difference of electronegativity, one atoms pulls shared electrons more towards itself and gets partial negative charge while the other atoms that has less electronegativity gets a partial positive charge.This electronegativity difference creates poles and a dipole moment in the whole molecule. The example of such a polar molecule is H2O.
However, sometimes the molecule is composed of atoms that have substantial electronegativity differences but still the molecule is not polar.
Why ?
Because the polar bonds are organized in a symmetrical way, in a way that the dipole moment of whole molecule becomes zero. This is because bond polarity is cancelled because of a symmetrical shape.
Take the example of carbon tetrachloride or CCL4. No doubt, chlorine and carbon have electronegativity difference and the molecule should be polar, but in actual it is not polar. If you look at the structure of CCl4 in attached figure, you can see that you can see that the shape of molecule is symmetrical. There is one bond on right and left each side of carbon , which cancel the net polarity of each other. One bond is on top and bottom of carbon each, that cancel the dipole moment of each other. Though electronegativity difference still exists but the overall molecule is non-polar. However, when the molecule reacts with some other atom or molecule and replaces chlorine atoms, the symmetry is broken and the resultant molecule becomes polar.
Hope it helps! :)
