What process is occurring as iodine solid is transformed into iodine vapor?
Luba_88 [7]
The process that is occurring as iodine solid is transformed into iodine vapour is SUBLIMATION.
Sublimation is the process by which a substance transformed from a solid state straight into a gaseous state without passing through the liquid state. Iodine is capable of undergoing sublimation process and this property is usually used to separate iodine from mixtures.<span />

In pea plants the trait for green sea pods ( G) is dominant over the trait for yellow seed pods (g) which cross will produce the
alexdok [17]

Answer:

See the answer below

Explanation:

The cross that would produce the maximum number of offspring with green sea pods would be:

1. GG x GG, or

2. GG x gg

The first one would produce all green offspring with homzygous genotypes as follows:

     GG   x   GG

 GG   GG   GG   GG

The second cross would produce all green offspring with heterozygous genotypes as follows:

      GG   x   gg

   Gg   Gg   Gg   Gg

At 700 K, CCl4 decomposes to carbon and chlorine. The Kp value for the decomposition is 0.76. Find the starting pressure of CCl4
Vladimir79 [104]
The decomposition of CCl4 is as follows:

CCl4 (g) ---> C(s) + 2Cl2 (g)                 Kp = 0.76

where Kp = (PCl2)^2 / (P_CCl4)

P_C is zero since carbon is in solid form.

Express P_CCl4 in terms of P_Cl2

0.76 = (P_Cl2)^2 / (P_CCl4)

0.76P_CCl4 = (P_Cl2)^2

Ptotal = P_Cl2 = 1.9 atm

Solve for P_CCl4

P_CCl4 = 4.75 atm<span />

Select all that apply to organic compounds,
ki77a [65]

Answer:

Organic compounds can be synthesized in a laboratory setting

Organic compounds contain carbon

There are hundreds of thousands of organic compounds,

Explanation:

Organic compounds are compounds that are found in life i.e plants and animals. The bulk of compounds that makes up living organisms are called organic compounds.

The idea that organic compounds can only be found in living organisms has been proven wrong by the synthesis of urea in the laboratory.

Organic chemistry studies compounds of carbons with the exception of oxides, carbides and carbonates.

All these other compounds of carbon apart from the above listed ones are called organic compounds.
