lys-0071 [83]3 years ago
5 0

Answer: Option (D) is the correct answer.

Explanation:

Noble gases are the elements that have completely filled orbitals.

For example, electronic configuration of neon is 1s^{2}2s^{2}2p^{6}.

Therefore, they do not react at ordinary conditions with any other element in the atmosphere.

Hence, they exist in pure form in the nature.

Thus, we can conclude that group of noble gases of elements is most likely to contain elements that will be found in pure nature.

What effect does<br>hybridization have on boods,​
Alchen [17]
Hybridisation influences the bond length and bond enthalpy strength in organic compounds. The sp hybrid orbital contains more s character and hence it is closer to its nucleus and forms shorter and stronger bonds than the sp3 hybrid orbital.

A flask contains an equal mixture of oxygen and argon. Which of the following statements is true about the effusion of the gases
frozen [14]
Given that the pressure, temperature and area of effusion is constant, the rate of effusion is inversely proportional to the square root of the molecular mass of the gas.
Mr Oxygen = 32
Mr Argon = 40
Effusion Oxygen = 1/√32
Effusion Argon = 1/√40
Effusion Oxygen / Effusion Argon = √(40) / √(32)
=√(40/32) = √(5/4) = 1.19
Thus, Oxygen will effuse 1.19 times faster than Argon. The second option is correct.

Modern pennies are composed of zinc coated with copper. A student determines the mass of a penny to be 2.483 g and then makes se
Aleonysh [2.5K]

Answer:

97.1%

Explanation:

Using the ideal gas equation, the number of moles of hydrogen gas produced can be calculated from information provided about the volume of gas evolved at a given temperature and pressure.

The stoichiometry of the reaction is now used to obtain the number of moles of Zn that will produce a given number of moles of hydrogen from the balanced reaction equation as shown. This gives us the number of moles of zinc reacted hence the mass of zinc in the coin since it is assumed that all the zinc reacts.

This is now used to calculate the mass percentage of Zn as shown.
