Answer:

Rain shadow

Explanation:

Climate is the average weather condition of a place over a long period of time.

The image shows a rain shadow effect around a mountainous region. The type of rainfall controlled this way is known as an orographic rainfall.

  • On the leeward side which is the opposite side of where the rain cloud forms, there is dryness and lack of rainfall.
  • As moist air rises along the edge of the windward side, cloud forms.
  • This windward side receives a significant amount of rainfall
  • The windward side is hit with cold and dry wind and it is barren.

Which of he following is a secondary alkanol?
hodyreva [135]

Answer: Thus CH_3CH(OH)CH_3 is a secondary alkanol.

Explanation:

Alkanol are compounds which contains carbons bonded by single bonds and contains hydroxy (-OH) as functional group.

Primary alkanol are those compounds which contain hydroxyl group attached a carbon which is further attached to a single carbon atom. Example: CH_3CH_2CH_2OH and CH_3CH_2CH_2CH_2OH

Secondary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to two more carbon atoms.Example: CH_3CH(OH)CH_3

Tertiary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to three more carbon atoms. Example: C(CH_3)_3OH

Thus CH_3CH(OH)CH_3 is a secondary alkanol.

Which types of atomic orbitals of the central atom mix to form hybrid orbitals in:<br> (c) PF₅;
zloy xaker [14]

The atomic orbitals of the central atom mix to form hybrid orbitals are one s and three p.

<h3>Which atomic orbitals are used to form hybrid orbitals?</h3>

Pauling supposed that in the presence of four hydrogen atoms, the s and p orbitals form four equivalent combinations which he called hybrid orbitals.

<h3>How many bonds does PF5?</h3>

Phosphorus pentafluoride has 5 regions of electron density around the central phosphorus atom (5 bonds, no lone pairs).

The resulting shape is a trigonal bipyramidal in which three fluorine atoms occupy equatorial and two occupy axial positions.

Define the following and give an example of each:_______.
Ber [7]
<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>\huge\textbf{Van de Waal}</h2>

London Dispersion force or Van de Waals force is a temporary attractive force which are the weakest and occur between nonpolar noble gases and same charges. This force is weaker because they have more electrons that are farther from the nucleus and are able to move around easier.

Example: N_2, F_2, \ I_2

<h2>_____________________________________</h2>

\huge\textbf{Dipole - Dipole Forces}

Dipole force is present between the polar molecules. Polar molecules are those molecules which have slightly negative and slightly positive charge. Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

Example: HCl, HF, CHCl_3

<h2>_____________________________________</h2>

\huge\textbf{Hydrogen Bonding}

It is a special type of dipole force present between polar molecules, it is formed between Hydrogen atom which forms positive ion, and the other negative ion. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom. The hydrogen bond is one of the strongest intermolecular attractions, but weaker than a covalent or an ionic bond.

Example: Every polar molecule which has hydrogen has hydrogen bonding i.e. H_2O, NH_3

How many grams of sodium bicarbonate are in 1.8 x 1023 formula units?NaHCO3
Makovka662 [10]

Answer:

Mass = 25.2 g

Explanation:

Given data:

Number of formula units of NaHCO₃ = 1.8×10²³

Mass in gram = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ formula unit

1.8×10²³formula unit × 1mol  /  6.022 × 10²³ formula unit

0.3 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 0.3 mol × 84 g/mol

Mass = 25.2 g
