An occluded front forms when a warm air mass is caught between two cooler air masses. The warm air mass is cut ofl or occluded' from the ground. The occluded warm front may cause clouds and precipitation. A swirling center of low air pressure is called a cyclone.

A comparison often made between solids and
Mandarinka [93]

The density of a plasma can be described as : ( A ) Low density

<h3><u>Density </u></h3>

Density is the mass per unit volume of a substance, it is used for comparison between substances because the mass and volume which are scalar quantities of substances are applied.

The density of plasmas are low when compared to solids because the volume occupied by a plasma of the same mass as a solid, is greater when compared to the volume occupied by a solid.

Hence we can conclude that The density of a plasma can be described as Low density.

29. Ammonia is formed with one nitrogen and three hydrogen atoms. What is the electron configuration of nitrogen? How
masya89 [10]

Answer:

<u>One lone-Pair is present in Ammonia</u>

<u></u>

Explanation:

The number of valence electron in N = 5

The number of Valence electron in H = 1

The formula of ammonia = NH3

Total valence electron in ammonia molecule = 5 +3(1) = 5+3 = 8

The lewis structure suggest that :

Nitrogen completes its octet by sharing the electron pair with 3 hydrogen atoms.

3 electron of Nitrogen are involved in sharing with Hydrogen

So,<u><em> remaining two electron are left non-bonded</em></u> . Hence they exist as lone- pair

So, there is only 1 lone pair in the ammonia molecule .

The shape of NH3 is bent according to VSEPR theory . This is so because the presence of 1 lone pair causes more repulsion and occupy more space.

Thus the lone pair is changing the shape of the ammonia molecule . It also increase the dipole moment of the molecule , which gives polarity to it.

Which statement about protons is false?
Alekssandra [29.7K]

<u>Answer:</u> The correct answer is Option 4.

<u>Explanation:</u>

There are three sub-atomic particles present in an atom. They are: electrons, protons and neutrons.

Protons constitute in each and every atom.

The charge on proton is of equal magnitude as that of electron but having opposite sign. Proton carry a positive charge and electron carry a negative charge.

Protons and neutrons, both determine the mass of an atom.

Mass of 1 proton = 1.007276 u

Mass of 1 neutron = 1.008664 u

Mass of 1 electron = 0.00054858 u

Mass of proton is almost same as that of neutron but is more than the mass of electron.

Hence, the correct answer is Option 4.
