B When the molecule contains polar bonds.

Explanation:

AP-EXpert

The shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

The polarization of a molecule greatly depends on the shape of the molecule. The net dipole moment occurs only due to the uneven distribution of electrons between the two atoms.

So we can conclude that the shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

Answer:

Suspension

Explanation:

Neon is transparent opaque as it is light, colorless and order less inert noble gas.

Noble gas are defined as the element that belong to group 18 of the modern periodic table.

It is also known as inert gas or aerogene.

Noble gas are light, transparent, colorless and order less gases.

They are the group of six inert or non reactive gases.

Noble gases are odorless, colorless, nonflammable gases with negligible chemical reactivity.

Noble gases are exceedingly stable and unlikely to form chemical bonds due to their complete valence electron shells, which have no tendency to add or lose electrons.

Noble gas were originally classified as group 0 in the periodic table because it was thought they had a valence of zero, which means their atoms could not mix with those of other elements to form compounds.

Thus, Neon is transparent opaque as it is light, colorless and order less inert noble gas.

Answer:

67 kg = 67 kg × 1×10⁶ mg / 1 kg

67 kg = 6.7×10⁷ mg.

Explanation:

The following data were obtained from the question:

Mass in Kg = 67 kg

Mass in mg =.?

Thus, we can obtain the mass in milligrams (mg) as follow:

1 kg = 1×10⁶ mg

Therefore,

67 kg = 67 kg × 1×10⁶ mg / 1 kg

67 kg = 6.7×10⁷ mg

Therefore, 67 kg is equivalent to 6.7×10⁷ mg

Answer:

sp2

Explanation:

Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.

C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is  sp2 hybridized.

Hence, the correct answer is "sp2".

The hybridization of the C atoms in C2Cl4 is sp² hybridized.

The concept of hybridization deals with the merging of atomic orbitals to produce fresh hybridized orbitals, which impact molecule geometry and bonding characteristics.

In the given compound, C2Cl4 (tetrachloroethene)

There is a substitution of all the hydrogen atoms attached to the organic compound ethene with chlorine to produce tetrachloroethene. The two carbon atoms are doubly bonded to each other with two chlorine attached to each of the carbon atoms diagonally given rise to a bond angle of 120°.  Thus, the resulting hybridization of the C atom is sp² hybridized.

Therefore, we can conclude that the hybridization of the C atoms in C2Cl4 is sp² hybridized.

Answer:

Option d is correct = Negative ion

Explanation:

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg  and 1.674929×10⁻²⁷ Kg  respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The  umber of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.

When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion. For example,

Anion formation:

X + e⁻ → X⁻

Cation formation:

X → X⁺ + e⁻

Thus option d is correct option.

Answer:

8.75×10¹³ mg

Explanation:

From the question given above, we obtained:

Mass (in Kg) = 8.75×10⁷ Kg

Mass (in mg) =?

Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:

1 Kg = 1000 g

Therefore,

8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg

8.75×10⁷ Kg = 8.75×10¹⁰ g

Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.

Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:

1 g = 1000 mg

Therefore,

8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g

8.75×10¹⁰ g = 8.75×10¹³ mg

Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.

Answer:

λ  = 3.0 × 10⁻¹² m

Explanation:

Speed of Light = Wavelength × frequency

c = λν

Step 1: Define

c = 3.0 × 10⁸ m/s

λ = unknown

ν = 1 × 10²⁰ Hz

Step 2: Substitute and Evaluate for λ

3.0 × 10⁸ m/s = λ · 1 × 10²⁰ Hz

λ = 3.0 × 10⁸ m/s ÷ 1 × 10²⁰ Hz

λ  = 3.0 × 10⁻¹² m

The geometry of PBr₃ is trigonal pyramidal. Therefore, option A is correct.

Trigonal pyramidal geometry refers to the molecular geometry around a central atom in a molecule or ion where there are three bonded atoms and one lone pair of electrons. This geometry is commonly found in molecules with a central atom surrounded by three bonding pairs and one non-bonding pair of electrons.

The term "trigonal" refers to the arrangement of the three bonding pairs, which are positioned in a flat, triangular shape around the central atom. The term "pyramidal" indicates that the lone pair of electrons occupies the fourth position, giving the molecule a three-dimensional pyramid-like shape.
