What are chemical properties of water?

Answers

The chemical property of water is oxidane. Water is tasteless, odorless at a normal temperature. Etc.
Water is covalently bonded (H-O-H). All simple covalent molecules such as these have low melting and boilong points. Water does not conduct electricity. It reacts with a lot of elements, especially vigorously with alkali metals

A positive ion has moreA. protons than electrons
B. electrons than protons
C. neutrons than protons

Answers

Final answer:

A positive ion, also known as a cation, has more protons than electrons as a result of losing electrons. For example, a sodium atom becomes a +1 sodium ion when it loses an electron. The number of neutrons does not affect the charge of ions.

Explanation:

A positive ion, also known as a cation, is formed when an atom loses one or more electrons. This causes the atom to have more protons than electrons, thereby gaining a positive charge. So, the correct answer to your question is A. Protons than electrons.

For instance, when a sodium atom (which has 11 protons and 11 electrons) loses an electron, it becomes a sodium ion with a +1 charge, having 11 protons and only 10 electrons.

Neutrons are particles present in the nucleus of an atom that do not carry any charge. Hence, the number of neutrons doesn’t affect the charge of ions.

Final answer:

A positive ion, or a cation, has more protons than electrons because it forms by losing electrons. Therefore, it has a net positive charge. The number of protons and neutrons doesn't change during this process.

Explanation:

A positive ion, also known as a cation, is formed when an atom loses electrons. The loss of electrons results in the atom having more protons than electrons, and subsequently more positive charge than negative, hence the name positive ion. Therefore, the correct answer to your question is A. protons than electrons. However, it’s important to note that the number of protons and neutrons in an atom does not change during chemical reactions or during the formation of ions.

After cloud droplets form, what must happen to them for precipitation to occur?

Answers

For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.

Which items are minerals or contain minerals? Check all that apply.asap please:)
-lawn fertilizer

-topsoil

-a diamond necklace

-a copper electrical wire

-a cellular phone

Answers

Answer:

Hey dude....

Explanation:

This is ur answer.....

Check all because all of them contain minerals.....

Hope it helps!

Brainliest pls!

Follow me! :)

Answer:

lawn fertilizer, topsoil, and a diamond necklace

Explanation:

lawn fertilizer and topsoil are coming out of the ground, therefore some amount of minerals will be in them, such as iron added to it to make whatever its going on grow stronger.

a diamond necklace is a jewel that is coming out of the ground. it is categorized as a raw mineral.

I'm not 100 percent sure about the copper wire and the cell phone.

I do belive copper is a mineral.
