Fill in the blanks for the following statements: The rms speed of the molecules in a sample of H2 gas at 300 K will be _________
Anna007 [38]

Answer : The rms speed of the molecules in a sample of H_2 gas at 300 K will be four times larger than the rms speed of O_2 molecules at the same temperature, and the ratio \mu _{rms}(H_2)/\mu _{rms}(O_2) constant with increasing temperature.

Explanation :

Formula used for root mean square speed :

\mu _{rms}=\sqrt{\frac{3RT}{M}}

where,

\mu _{rms} = rms speed of the molecule

R = gas constant

T = temperature

M = molar mass of the gas

At constant temperature, the formula becomes,

\mu _{rms}=\sqrt{\frac{1}{M}}

And the formula for two gases will be,

\frac{\mu _{H_2}}{\mu _{O_2}}=\sqrt{\frac{M_{O_2}}{M_{H_2}}}

Molar mass of O_2 = 32 g/mole

Molar mass of H_2 = 2 g/mole

Now put all the given values in the above formula, we get

\frac{\mu _{H_2}}{\mu _{O_2}}=\sqrt{\frac{32g/mole}{M_{2g/mole}}}=4

Therefore, the rms speed of the molecules in a sample of H_2 gas at 300 K will be four times larger than the rms speed of O_2 molecules at the same temperature.

And the ratio \mu _{rms}(H_2)/\mu _{rms}(O_2) constant with increasing temperature because rms speed depends only on the molar mass of the gases at same temperature.

What is meant by saying that the latent heat of vaporization of water is 22. 5×10^5 j/kg.
andrey2020 [161]

It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.

Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.

Boiling point of the water is 100°C.

Joule (J) is the standard unit for energy (in this example heat).

Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

What type of compound involves the transfer of electrons?
astra-53 [7]

Answer: Electrovalent or Ionic Compounds

Explanation:

Electrovalent Compounds Form bonds that are characterised by transfer of electrons from metallic atoms to non-metal licenses atoms during a chemical reaction.

The metallic atom after donating their valence electrons, become positively charged, while the non-metal license atoms becomes negatively charged after acquiring extra electrons.

A typical example of electrovalent compounds can be found between the association of Group 1(Alkali Metals) elements and the Group 7(Halogen Family) elements.
