Answer:

condensation

Explanation:

Frost forms when an outside surface cools past the dew point. The dew point is the point where the air gets so cold, the water vapor in the atmosphere turns into liquid. This liquid freezes. If it gets cold enough, little bits of ice, or frost, form

Answer:

Option C. Triple the number of moles

Explanation:

From the ideal gas equation:

PV = nRT

Where:

P is the pressure

V is the volume

n is the number of mole

R is the gas constant

T is the absolute temperature.

Making V the subject of the above equation, we have:

PV = nRT

Divide both side by P

V = nRT / P

Thus, we can say that the volume (V) is directly proportional to both the number of mole (n) and absolute temperature (T) and inversely proportional to the pressure (P). This implies that and increase in either the number of mole, the absolute temperature and a decrease in the presence will cause the volume to increase.

Thus, the correct option is option C triple the number of moles. This can further be seen as illustrated below:

Initial volume (V1) = 12 L

Initial mole (n1) = 0.5 mole

Final mole (n2) = triple the initial mole = 3 × 0.5 = 1.5 mole

Final volume (V2) =?

From:

V = nRT / P, keeping T and P constant, we have:

V1/n1 = V2/n2

12/0.5 = V2/1.5

24 = V2/1.5

Cross multiply

V2 = 24 × 1.5

V2 = 36 L.

Thus Option C gives the correct answer to the question.

Answer:

Al3+

Explanation:

Aluminium has an electronic configuration of 2, 8, 3 and the outermost valence electrons is +3 since it is a metal

Elements acquire positive or negative charges by losing or gaining electrons. The element which have 3+ charge among the options is boron (B) Hence, option B is correct.

Boron is 5th element in periodic table and it is classified into 13th group. Boron is a metalloid and shows properties intermediate to metals and non metals.

The electronic configuration of boron is K =2, N =3. Atoms lose or gain electrons as per their valency to become stable. According to octet rule atoms become stable when their valence shell get completely filled.

Boron have 3 electrons in its valence shell. If it donate these three electrons into an electronegative atom, its K shell become its valence shell and it is completely filled. Thus boron becomes stable.]

When atoms loses electrons they acquire positive charge and this charge is numerically equal to the number of electrons lost. Thus boron acquire 3 unit of positive charge by donating its 3 electrons. Hence, option B is correct.

The fossil provide scientists about the way this area might have changed over time, the evidence It shows that the mountain may have once been underwater and was raised by natural processes.

Any surviving remnants, impression, or evidence of a once-living creature from a previous geological epoch is referred to as a fossil. Examples include fossilized bones, shells, exoskeletons, animal or microbe impressions in stone, amber-preserved artifacts, hair, petrified wood, oil, coal, and DNA traces.

There are four basic categories of fossils, each generated in a unique method and useful for conserving various kinds of animals. These include genuine form fossils, trace fossils, mold fossils, and cast fossils.

Usually, sedimentary rocks include fossils, however rarely, low-grade, fine-grained metamorphic rocks will as well. Sometimes, after the fossils have been removed, the surrounding rock has developed molds.

Answer:

Mass can neither be created nor destroyed in a chemical equation, it  transfer from one to another form.

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

A molecule's shape greatly influences the polarity of the compound, the molecular structure has an impact on molecular characteristics. The shape of a molecule affect the molecule's function. Therefore, option B is correct.

Based on the environment, the term may or may not include ions that meet this requirement. A molecule is a collection of two or more atoms held together by the attractive forces known as chemical bonds.

Molecule shape play a key role in anticipating how one molecule may interact with another, as well as in determining macroscopic features like melting and boiling points.

Polar substances have higher boiling and melting temperatures, tend to dissolve in other polar compounds, and can either form solids or liquids.

Thus, option B is correct.
