Learning Task No. 3: Write a short paragraph regarding the differences between
saturated and unsaturated solutions.
Type of Solution
Explanations about the differences of
the two solutions
Saturated solution
Unsaturated solution
Answers
Answer:
See explanation
Explanation:
A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

Conglomerate rocks are colorful and attractive; however, it is rarely used as ornamental stone for interior use because of its unreliable physical strength and durability.
Conglomerate has very few commercial uses, though it can be crushed to make a fine aggregate that can be used when a low-performance material is needed.
Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. Because of the large size of the clasts, it takes a very strong water current to transport and shape the rocks. As they tumble through the running water or moving waves, they form their rounded shape.
These rocks can be found in sedimentary rock sequences of all ages. They probably make up less than one percent by weight of all sedimentary rocks.

a Molecules
b lons
C Pure elements
d All of the above
Answers
Answer:
D. All of the above
Explanation:
Molecules, ions, and pure elements might be included in a chemical reaction. Therefore, option (d) is correct.
What is a chemical reaction?A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.
The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.
Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.
Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.

Answers
Answer:
No
Explanation:
The physical and chemical properties of substances are usually difference from those of the elements that makes them up.
Compounds are substances composed of two or more kinds of atoms joined together in a definite grouping.

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane
Answers
Answer:
C. the carbons in ethene are linked by double bonds
Explanation:
The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.
In single bonds afforded with the ethane compound, there is free rotation.
The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.

How do the products of chemical reactions compare to their reactants? Question 5 options: The products usually weigh more than the reactants. The products often have completely different properties than the reactants. The products usually have more atoms than the reactants. The products are usually more toxic than the reactants.
Answers
Answer:
The products often have completely different properties than the reactants.
Explanation:
In a chemical reaction, the products are often completely different from the reactants.
When chemical reactions takes place, the species rearranges to form new bonds and to attain stability.
Therefore, the new products formed usually have completely different properties when compared to the reactants.
Also, in chemical reactions, mass is always conserved. The mass of the products and reactants are usually the same.
