How can you recognize an alcohol answers?
ira [324]
You can identify a compound to be an alcohol when it has a hydrocarbon chain and a hydroxyl functional group or -OH group. Also, from the name, you can tell that it is an alcohol is the suffix -ol is present. Examples are ethanol and methanol.  Alcohol is any organic substance that contains an hydroxyl group bonded to a carbon atom that is saturated. Alcohols can be classified as primary, secondary or tertiary depending on where the hydroxyl functional group is attached in the hydrocarbon chain. It is a primary alcohol when OH is attached to  the first carbon atom. Secondary alcohol, and tertiary alcohols has a general formula CHROH and CR2OH, respectively where R represents a hydrocarbon chain.<span />

The chemical equation for the formation of ammonia is unbalanced.
galben [10]

Answer:

The answer to your question is 2 molecules

Explanation:

Unbalanced chemical reaction

                   H₂(g)   +   N₂(g)   ⇒   NH₃ (g)

         Reactants         Elements          Products

                2                      H                       3

                2                      N                       1

Balanced chemical reaction

                   3H₂(g)   +   N₂(g)   ⇒   2NH₃ (g)

         Reactants         Elements          Products

                6                      H                       6

                2                      N                       2

From the balanced chemical reaction we conclude that when 3 molecules of hydrogen react with one molecule of nitrogen, 2 molecules of ammonia will be formed.
