Compound A, C12H22O, undergoes reaction with dilute H2SO4 at 50°C to yield a mixture of two alkenes, B and C, C12H20. The major

Nataly_w [17]

Answer:

Compound C is an alkene containing two cyclohexane rings attached with each other through a single bond.

Explanation:

Only cyclohexanone is obtained after ozonolysis of major alkene product. This means major alkene product, B , should contain contain two cyclohexane rings attached with each other through a double bond.
Compound B and C are obtained after dehyration of compound A by treating it with dilute $H_{2}SO_{4}$ at $50^{0}\textrm{C}$ . So, compound A is an alcohol.
As compound B is obtained from compound A therefore compound A is an alcohol containing two cyclohexane rings attached with each other through a single bond.

What is the molecular formula of compound x?

givi [52]

Since there is one carbon with 4 Fluorines attached to it, and both compounds are no metals, we use the covalent method for naming,

Here we ignore the prefix for the first element if it is 1. Mono. Then pay attention to the second one, it would be tetra, because tetra means 4. Here there are 4 fluorines.

Drop ine and place ide

CF4 = carbon tetrafluoride.

If the concentration of brown sand is 2.0 ppm, how many grains of brown sand are in the bucket?

AysviL [449]

I believe the complete given is that the bucket of sand contains 9.5 billion grains of sand. That is:

bucket = 9,500,000,000 grains

and the concentration of brown sand is 2 ppm:

concentration brown sand = 2 / 1,000,000

Therefore:

brown sand = 9,500,000,000 * (2 / 1,000,000)

<span>brown sand = 19,000 grains</span>
