Answer:

Because the intermolecular interactions are weaker.

Explanation:

Nonpolar substances do not have dipole-dipole or hydrogen bond interactions, which are strong intermolecular interactions that often make the substance liquid or solid. Instead, they must rely on van der Waals forces, which are relatively weaker interactions that are often insufficient to hold the molecules together in liquid or solid form.

The magnitude of intermolecular association in nonpolar substance is much lower than the magnitude of intermolecular association in polar substances.

Polar substances are those substances in which a permanent dipole exists in the molecule. In a molecule having a permanent dipole, the electronegativity difference between the atoms bonded in the molecule is high.

As a result of this high electronegtivity difference between atoms, the molecules interact more intimately hence polar molecules tend to exist mostly as liquids and gases while nonpolar molecules having less intimate intermolecular interaction via dispersion forces exist mostly as gases.

Explanation:

They are in the same group

Answer:

2CO >>> 2C + O2

........

Answer:

Options d.

Explanation:

As white light from the sun is passed through a prism, it is separated into colors - red, violet, yellow, blue, green, orange, and indigo.

Dispersion is the process of the separation of visible light into its different component colors. The light waves are refracted as they enter the prism.

So, option d. is correct.

Answer:

The clear liquid is less dense than the black liquid, which is why it floats on top. If the volume were different, you would visually see more clear liquid than black and vice versa.

The clear liquid is less dense than the black liquid

Answer:

A. The clear liquid is less dense than the black liquid

Explanation:

Since the clear liquid since on top of the black one it's density is less. Whatever liquid has a higher density will sink to the bottom of the flask.

The process of photosynthesis is the process of converting carbon dioxide and water into energy in the form of carbohydrates using sunlight. Usually done by plants that have leafy za called chlorophyll.

Carbohydrates themselves are formed from the C-carbon, H-hydrogen and O-oxygen components

Rabbit food is carrots that contain carbohydrates, which are part of the photosynthesis process

3. The carrot plant takes in carbon dioxide from the air during photosynthesis.

Reaction

6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂

2. The rabbit eats the carrot plant.

Rabbits meet their carbohydrate source for energy by eating carrots

1. The rabbit decomposes.

Rabbits in time will experience a process of decomposition

4 - Carbon compounds are returned to the soil.

The carbon content in rabbits will also be decomposed into the soil again

Answer:

62.5 km/hr

Explanation:

Speed can be found by dividing the distance by the time.

s=d/t

We know the car travelled a distance of 125 kilometers in 2 hours. Therefore:

• d=125 km

• t= 2 hr

Substitute the values into the formula.

s= 125 km/ 2 hr

Divide

s= 62.5 km/ hr

The speed of the car is 62.5 kilometers per hour.

Answer:It is a nuclear process, where energy is produced by smashing together light atoms. It is the opposite reaction of fission, where heavy isotopes are split apart.

Explanation Fusion is the process by which the sun and other stars generate light and heat.

It’s most easily achieved on Earth by combining two isotopes of hydrogen: deuterium and tritium. Hydrogen is the lightest of all the elements, being made up of a single proton and a electron. Deuterium has an extra neutron in its nucleus; it can replace one of the hydrogen atoms in H20 to make what is called “heavy water.”

The correct name of the compound whose chemical formula is Na₂SO₄ is sodium sulfate.

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.

There are four types of chemical formula:

1)empirical formula

2) structural formula

3)condensed formula

4)molecular formula

Explanation:

The classic rainbow is made of certain colors, so If a white light passed through a glass prism [and only glass] the rainbow would show because of the colors bending [the naked eye can't see that 0-0]

Also, you know the sky is blue right??  The color blue in that prism when the light shined over was the shortest and wavy color. each color has it's own wave. blue is just the shortest and waviest one.
