Which functional group does the molecule below contain? HIC H H=COH [

katrin2010 [14]

Answer:

$D. \ \ \ \text{hydroxyl}$

Explanation:

Alcohols are organic compounds that are composed of the hydroxyl function group ( $-\text{OH}$ ), bonded to a carbon atom of an alkyl or a substituted alkyl group. Hence, the functional group of alcohols is the hydroxyl group ( $-\text{OH}$ ).

According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature, alcohols are named by changing the -e ending of the name of the parent alkane to the suffix -ol.

For example, the alcohol molecule in the figure demonstrates a hydroxyl group bonded to a methyl group. Therefore, the name of the alcohol is methanol.

Energy Sources (6 points) A. Sort the types of energy into the "renewable" and "nonrenewable" columns. (1 point)

denpristay [2]

Explanation:

(A) Renewable resources are defined as the resources that can be used again and again.

For example, wind, hydroelectric energy, geothermal etc.

On the other hand, resources which cannot be used again and again and which cannot be replaced by natural means are known as non-renewable resources.

For example, coal, petroleum etc are all non-renewable resources.

Therefore, given options are distinguished as follows.

Renewable energy : Wind, Hydroelectric, Geothermal, Biomass, and Solar.

Non-renewable energy : Coal, Petroleum, Natural gas.

(B) Fuels which decompose for a long period of time and which arise from old life forms are known as fossil fuels.

If 16 moles of al react with 3 moles of S8 how many moles of Al2 S3 will be formed

Gnom [1K]

Answer:

8 moles

Explanation:

Al reacts with $S_8$ to produce $Al_2S_3$ as

$Al+S_8\rightarrow Al_2S_3$

The balanced chemical equation is

$16Al+3S_8\rightarrow 8Al_2S_3$

In the reaction, 16 moles of $Al$ react with 3 moles of $S_8$ to produce 8 moles of $Al_2S_3$ .
