Answer:
Yes
Explanation:
The rate at which a solute dissolves depends upon the size of the solute particles. Dissolving is a surface phenomenon since it depends on solvent molecules colliding with the outer surface of the solute.

Which of the following are held together by nonpolar covalent bonds? PLEASE HELP
Answer:
The atoms of chlorine are held together by non-polar covalent bonds. Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference. For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
C. Atoms of chlorine (CI)
A covalent bond is created when the electrons from the two involved atoms are shared equally.The pair of electrons involved in this kind of bonding is referred to as the shared pair or bonding pair. Here the atoms of chlorine have non-polar covalent bonds. The correct option is C.
What are non-polar covalent bonds?A non-polar covalent connection is created when atoms with an equal amount of electrons share one another. The electronegativity of the two atoms is equivalent. When two atoms with similar electron affinities join together, like in the case of diatomic elements, it happens.
Non-polar covalent compounds are those in which there is no variation in electronegativity. In these compounds, the electronegativity does not change, preventing the motion of the bond pair's electrons in the direction of the linked atoms.
As a result, a molecule is non-polar and non-conducting since there is no bond or dipole moment between its atoms and no buildup of charges on the atoms.
Thus the correct option is C.

What is a fossil?
The remains of an animal or plant preserved within a layer of rock?
A orange body of compacted ice formed over thousands of years?
The energy radiated from sun?
A change in the structure of earths surface?
Answer:
the remains of an animal or plant preserved within a layer of rock otherwise A.
A fossil is the remains of an animal or plant preserved within a layer of rock. The correct option is A.
What are fossils?Fossils are the preserved form of animals or plants that are preserved on rocks or deep in the earth's crust and did not get damaged. They are discovered in the digs that are done by paleontologists.
The bones and sometimes dry skins and hairs, and teeth are also found that are preserved. These fossils help in studying animals and plants that were present in former times.
They do not get destroyed because they are preserved in rocks and stones. We got to know about dinosaurs by their fossils. There are different types of fossils are found.
Thus, the correct option is A. The remains of an animal or plant are preserved within a layer of rock.

10 points
Answer:
false
Explanation:
According to the law of conservation of energy, energy can neither be created nor destroyed but can be converted from one form to another. Hence, the given statement is true.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of energy is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

Jacob walked into a shop to buy cups for his house. He saw the cups shown below. Why does the cup on the right appear yellow? A. The cup absorbs yellow light but reflects all other colors of light. B. The cup reflects yellow light but refracts all other colors of light. C. The cup refracts yellow light but absorbs all other colors of light. D. The cup reflects yellow light but absorbs all other colors of light.
Answer:
D. The cup reflects yellow light but absorbs all other colors of light.
Explanation:
The cup in the shop appears yellow because the cup reflects yellow light but absorbs all colors of light.
Due to the materials the cup is made of, it is able to specifically reflect yellow and absorb other radiation types.
The color we see are products of the part of visible radiations they reflect.
The cup in this instance reflects yellow and absorbs other color.
