I’m pretty sure it would be B and C because plant roots as they get larger can crack rocks, even split them in half.

Whats the difference between covalent and ionic bonds

il63 [147K]

Answer: The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms.Jan 23, 2020

Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be s

Blizzard [7]

Answer:

See figure 1

Explanation:

In this question, we have to find first the chiral carbons on 1,2-difluoro-1,2-dimethylcyclopentane. Carbons 1 and 2. Then, using the Cahn–Ingold–Prelog priority rules. We can draw all the stereoisomers. If we have 2 chiral carbons we will have ( $2^n=2^2=4$ ) 4 isomers. With this in mind we can have the R,R isomer; the S,S isomer; the S,R isomer, and the R,S isomer. We have to remember that:

Priority 1 = "F"

Priority 2= "C"

Priority 3= "CH2"

Priority 4 = "CH3"

I hope it helps!

Why is knowledge of mineral properties important? Which properties might be most useful in construction? In jewelry-making? Expl

Mashcka [7]

Answers with Explanations:

1. Why is knowledge of mineral properties important?

Knowledge of mineral properties is important because it helps scientists know about the earth's history, particularly when it comes to "rock formations." It is also essential in order to know which minerals are economically important.

2. Which properties might be useful in construction?

Minerals have many physical properties (color, crystal form, hardness, luster, density, cleavage and fracture, etc.)

When it comes to construction purpose, the mineral's malleability is very important. This is the reason why "iron" is one of the most important minerals being used in buildings. It's malleability allows it to be framed into "steel," which is then used to make even bigger infrastructures and skyscrapers.

3. In jewelry-making?

When it comes to "jewelry-making," the hardness and luster of the mineral may be used as a basis. For example, the diamond can be determined from the rest of the minerals because it is the hardest and it has a brilliant-kind of luster.
