Help pls thnk you!!!!

The amine here is the easiest to spot since there’s only one structure that has a nitrogen atom, which would be the first (the first structure is a primary amine).

The distinguishing functional group of an alcohol is the hydroxy group (—OH). Both the second and third structures have an —OH group, but the —OH in the third structure is part of a carboxyl group (—COOH or —C(=O)OH). A carboxyl group takes priority over hydroxy group. Thus, the second structure would be an alcohol and the third structure would be a carboxylic acid.

That leaves us with the fourth structure, a hydrocarbon with a halogen substitutent, or, aptly named, a halocarbon.

When a gas is dissolved in a liquid, what happens when the pressure increases?<br>​
erik [133]

Answer: B, the gas is being squeezed out of the liquid.

If 6.02*10^23 molecules of ammonia react with 12.04*10^23 molecules of hydrogen chloride, how many molecules are in the reaction
Helen [10]

Answer:

18.06 × 10²³ molecules

Explanation:

Add the two amounts of molecules together.

6.02 × 10²³  +  12.04 × 10²³  =  18.06 × 10²³

You will have 18.06 × 10²³ molecules in the vessel when the reaction is complete.  This is because of the Law of Conservation of Mass.  Mass is neither created nor destroyed in chemical reactions.  You will have the exact number of molecules in the reaction vessel as you did in the beginning.  The types of molecules may change, but the number will stay the same.
