Goshia [24]

Answer:

i belive its c

Explanation:

Atoms of group 18 elements have eight valence electrons (or two in the case of helium). These elements already have a full outer energy level, so they are very stable. As a result, they rarely if ever react with other elements. Therefore, it is very reactive and gives up electrons in chemical reactions.

Answer:

See the answer below

Explanation:

Organic molecules in the form of carbohydrates are created during photosynthesis or chemosynthesis and these processes cause carbon to be removed from the atmosphere or other environment into the biosphere - the living organisms of the ecosystem.

During photosynthesis, atmospheric carbon dioxide is fixed as carbohydrates into green plants in a two-stage process that requires sunlight energy and water. The entire process can be summarized as an equation below:

$6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2$

Instead of using water as a reactant, chemosynthetic organisms make use of high energy chemicals such as hydrogen sulfide to fix carbon dioxide in order to generate carbohydrates.

$CO_2 + 4H_2S + O_2 -> CH_20 + 4S + 3H_2O$

Both processes ensure that carbon dioxide moves from the environment into living organisms.

Free radical chlorination of ethane can produce higher halogenation products (dichlorinated, trichlorinated, etc...) in addition

Kryger [21]

Answer:Use an excess of ethane

Explanation:

The halogenation of alkanes is a substitution reaction. All the hydrogen atoms in the alkanes could be potentially substituted. How ever the reaction can be controlled by using an excess of either the alkane or the halogen. If the aim (as it is in this question) is to minimize the yield of halogenated alkanes, an excess of the alkane (in this case, ethane) is used.
