Difference between calcium sulfide and calcium sulfate.

const2013 [10]

Answer: Calcium sulfide is a chemical compound having formula CaS. While Calcium sulfide is inorganic compound g fomlaCaSO4.

Explanation:

calcium sulfide is use in preparation of hydrogen sulfide, luminous pain and as a depilatory in cosmetics while calcium sulfate is used as desiccant. calcium sulfides is white material crystallizes in cubes like rock salt while calcium sulfate has three different crystalized forms known as hemihydrate (CaSO4⋅12H2O) , anhydrate (CaSO4) and as gypsum (CaSO4⋅2H2O). hope this explanation will be helpful for you

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!

A primary amine contains a five-membered carbon ring. The degree of unsaturation for the five-membered carbon ring is equal to t

IceJOKER [234]

Answer:

C₇H₁₁N

Explanation:

To find the chemical formula, first, let's evaluate the given conditions.

1. Is a primary amine:

This means that the amine is connected to a carbon, like NH₂-R

2. The degree of unsaturation of the five-membered carbon ring is equal to three:

One of the degrees of unsaturation is for the five-membered carbon ring, the other two are for pi-bonds. This means that the five-membered carbon ring has 2 pi-bonds inside.

3. There are seven carbon atoms:

Five of these seven carbons are for the carbon ring and the other two are bonded to the primary amine.

From all of the above, we have that the chemical formula is:

C₅H₅-C₂H₄-NH₂ = C₇H₁₁N

I hope it helps you!

This is pseudoscience, because:
1) The researchers were so excited to report that they had discovered a fuel that burns so hot that it becomes cold. - This would have to be proven again. It may not be this that caused the explosion.
2) Much to the relief of the original team or researchers, no other scientist could ever replicate their find. - It can't be replicated, so once again, it proves that it may not be that the fuel burns so hot it becomes cold
3)The researchers quickly wrote up a report, created a press release, and applied for a patent. - The report can have errors if it had been 'quickly' written. Also, because it could not be replicated, there is no need for a patent, as it could not be 'proven' again

hope this helps
