The name of that product is 1-nonene.

The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.

The prefix none is because it has 9 carbon.

And the use of number 1 is because the double bond is in the carbon number 1.

Can u guys help on 22. It will only take a min.
Anni [7]

Answer:

Alpha > beta>gamma

Explanation:

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.
