sweet [91]

<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.

<u>Explanation:</u>

A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.

Carbon is the 6th element of the periodic table having electronic configuration of 1s^22s^22p^2

This element requires 4 electrons to complete its shell.

Oxygen is the 8th element of the periodic table having electronic configuration of 1s^22s^22p^4

This element requires 2 electrons to complete its shell.

So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.

Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.

Which of these is not a postulate of the kinetic-molecular theory of gases?
marin [14]

a) Gas particles have most of their mass concentrated in the nucleus of the atom.

b) The moving particles undergo perfectly elastic collisions with the walls of the container.

c) The forces of attraction and repulsion between the particles are insignificant.

d) The average kinetic energy of the particles is directly proportional to the absolute temperature.

e) All of the above are postulates of the kinetic molecular theory.

Gas particles have most of their mass concentrated in the nucleus of the atom.

Answer: Option A.

<u>Explanation:</u>

Kinetic Molecular Theory expresses that gas particles are in consistent movement and show flawlessly versatile crashes. Motor Molecular Theory can be utilized to clarify both Charles' and Boyle's Laws. The normal active vitality of an assortment of gas particles is straightforwardly corresponding to total temperature as it were.

The kinetic theory of gases is a significantly critical, however straightforward model of the thermodynamic conduct of gases with which numerous important ideas of thermodynamics were built up.

What is the mass of one mole of hydrogen molecules?
Lilit [14]

Answer:

2 grams

Explanation:

One MOLE of hydrogen atoms contains the same number of atoms as the number of hydrogen molecules in one MOLE of hydrogen molecules, i.e., Avagadros number. However, one mole of hydrogen atoms has a mass of 1 gram while one MOLE of hydrogen molecules has a mass of 2 grams.

Air is made up mostly of O2, N2, and CO2. If the total pressure of air is 765mmHg and P(N2) = 0.79 atm and P(CO2) = 0.05 atm, th
Mrac [35]

Answer:

the partial pressure of the O2 is 0.167 atm

Explanation:

The computation of the partial pressure of the O2 is shown below:

As we know that

P = P_N2 + P_O2 + P_CO2

P_O2 = P - P_N2 -  P_CO2

= (1.007 - 0.79 - 0.05)

= 0.167 atm

Hence, the partial pressure of the O2 is 0.167 atm

we simply applied the above formula
