How does a sample of hydrogen at 10 °C compare to a sample of hydrogen at 350 K?

Chemistry

Answer: -

The hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Explanation: -

Temperature of the hydrogen gas first sample = 10 °C.

Temperature in kelvin scale of the first sample = 10 + 273 = 283 K

For the second sample, the temperature is 350 K.

Thus we see the second sample of the hydrogen gas more temperature than the first sample.

We know from the kinetic theory of gases that

The kinetic energy of gas molecules increases with the increase in temperature of the gas. The speed of the movement of gas molecules also increase with the increase in kinetic energy.

So higher the temperature of a gas, more is the kinetic energy and more is the movement speed of the gas molecules.

Thus the hydrogen at 10 °C has slower-moving molecules than the sample at 350 K.

Determine the molecular geometry based on the description of bonding and lone pairs of electrons around the central atom. Three
Inessa05 [86]

Answer:

Three double bonds and no lone pairs of electrons- trigonal planar

Two single bonds and two lone pairs of electrons-bent

Five single bonds and no lone pairs of electrons- trigonal bipyramidal

Three single bonds and one lone pair of electrons- trigonal pyramidal

Two double bonds and no lone pairs of electrons - linear

Four single bonds and no lone pairs of electrons- tetrahedral

Six single bonds and no lone pairs of electrons- octahedral

Explanation:

The valence shell electron pair repulsion theory gives a description of the shape of a molecule based on the number of regions of electron density present on the valence shell of the central atom of the molecule.

The molecules are distorted away from the shape predicted on the basis of the VSEPR by the presence of lone pairs on the valence shell of the central atom in the molecule. In the absence of lone pairs, the shape of a molecule is exactly the shape predicted on the basis of the VSEPR theory.

This gas law works only if temperature is recorded in ———— units
Vsevolod [243]

Answer:

Kelvin

Explanation:

  • Gas laws re the laws that relates properties of gases such as pressure, temperature and volume at different conditions.
  • Gas laws includes, Boyle's law, Charles law, grahams law and pressure law among others.
  • Temperature is one of the quantity of gases explained by gas laws. For gas laws to work, temperature should always be in Kelvin. Therefore, when given temperature in degrees, it is converted to Kelvin by adding 273, that is °C + 273 = K.
