What is the most likely mode of decay for each?(c) ¹¹⁰₄₁4Ru
zmey [24]

The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton.

<h3>What is radioactive decay?</h3>

The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent kinds of decay, and they all entail the emission of one or more particles. Beta decay is a result of the weak force, while the nuclear force and electromagnetism are in charge of the other two mechanisms. The capture of an inner electron from one of the electron shells by an unstable nucleus is the fourth prevalent form of decay.

Infer: Why might a zone of upwelling be a good place to fish?
Aleks [24]

First lets define upwelling

Upwelling- a rising of seawater, magma, or other liquid

In this case, you would be looking at a river, lake, ocean, or other body of water good for fishing.

You'd want to look for a place with upwelling because when there is a rise of water, the sea creatures within it will rise too. So the fish in the bottom of a lake for example would be brought up to the surface of the water or near the surface which is where your fishing rod is trying to grab the fish.

I hope this helps! Don't be afraid to reach out with any further questions!

Answer:

PBr3 - Molecule , Polar

N2H2 - Molecule , (Polar in E- form and Non- polar in Z form)

C2H2 - Molecule , Non- Polar

N2 - Molecule , Polar

NCl3 - Molecule , Polar

SiF4 - Molecule , Non- Polar

NH3 - Molecule , Polar

F - Not- Molecule (atom)

H2 - Molecule and Non- Polar

Explanation:

Molecule : these are group of two or more atoms joined by strong force of attraction.

H2  is non- polar because it is homoatomic molecule.(made up of same element)

N2 is non- polar because it is homoatomic molecule.
