A primary amine contains a five-membered carbon ring. The degree of unsaturation for the five-membered carbon ring is equal to t
IceJOKER [234]

Answer:

C₇H₁₁N

Explanation:

To find the chemical formula, first, let's evaluate the given conditions.

1. <u>Is a primary amine</u>:

This means that the amine is connected to a carbon, like NH₂-R

2. <u>The degree of unsaturation of the five-membered carbon ring is equal to three</u>:

One of the degrees of unsaturation is for the five-membered carbon ring, the other two are for pi-bonds. This means that the five-membered carbon ring has 2 pi-bonds inside.

3. <u>There are seven carbon atoms</u>:

Five of these seven carbons are for the carbon ring and the other two are bonded to the primary amine.

From all of the above, we have that the chemical formula is:

C₅H₅-C₂H₄-NH₂ = C₇H₁₁N  

I hope it helps you!

shtirl [24]

Answer:

Kindly check explanation

Explanation:

The force applied is directly proportional to the distance moved by an object, the larger the applied force, the greater the distance moved.

a = f/m

a = acceleration ; f = applied force ; m = mass

From the relation, we can see that acceleration is directly proportional to force applied.

The ball will travel farthest with the greatest applied force while, nearest distance will be attained with the smallest applied force.

The distance covered is affected by both the mass of the object and the applied force

Net ionic equation for 2AgF(aq) + k2S = Ag2S (s) + 2KF(aq)
tester [92]

Answer:

The net ionic equation shows the actual reaction more clearly and closer to reality because it writes soluble ionic compounds as the ions and then cancel the spectator ions not involved in the chemical reaction . The net ionic equation results shows the actual chemical reaction taking place.
