Answer:

Alkali Earth Metals

Explanation:

The oxidation number is equal to the charge which is determined by the valence electrons. Alkali Earth Metals all have 2 valence electrons and, therefore, an oxidation number of 2.

Answer:

+2alkaline earth metal and +1 oxidation number is alkali metal

Explanation:

alkali is Arabic word means ash

Answer: Yes- Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust.

A buffer is made from an acid - base conjugate pair as shown by option A

Buffers are often composed of weak acids and their conjugate bases (or weak bases and their conjugate acids). The weak acid can contribute a proton to balance any new base, whereas the conjugate base can absorb a proton to do so.

This balance between the acid and its conjugate base allows the buffer to survive pH changes. Buffers are essential in biological systems because many biochemical processes are particularly sensitive to pH changes.

Helium

Explanation:

The first ionization energy varies in a predictable way across the periodic table.

Answer:

Sublimation is the transition in physical state from solid (ice) to vapor with no intermediate liquid stage. In other words, the ice becomes water vapor without melting. Ideal weather conditions would be low humidity (to allow vaporization), high altitude (lower air pressure facilitates the transition), and strong sunlight (to provide the energy for the transition). High snow-packed mountain ranges offer all of these conditions. Since the temperature is too cold for evaporation, sublimation is needed to provide enough water vapor to feed the water cycle and promote precipitation elsewhere on the planet. Without it, the water would stay frozen in the snow and ice and reduce the amount of liquid water that would replenish the planet.

Answer:

noble gases

The noble gases rarely form compounds. They have the most stable configuration (full octet, no charge), so they have no reason to react and change their configuration. All other elements attempt to gain, lose, or share electrons to achieve a noble gas configuration

Answer:

1. Sodium has a charge of 1+ and chlorine has a charge of 1-

Explanation:

Sodium has 11 protons and 11 electrons. If you remove one electrons we now have only 10 electrons.

Hence; number of protons - number of electrons = 11 - 10 = +1

Sodium has a charge of +1

Chlorine has 17 electrons and 17 protons. if it gains 1 electron then it now has 18 electrons.

Hence; number of protons - number of electrons = 17 - 18 = -1

Chlorine has a charge of -1

Explanation:

The potassium is an alkali metal which explode in water to produce base and hydrogen gas.  The balancing came from the fact that each side needed the same number of hydrogens so I made the products have 4 (the lowest even number) then put the appropriate coefficients in the reactants to make that work.  Since there are two molecules of potassium hydroxide there also needed to be 2 atoms of potassium in the reactants.

Which nuclear force holds the nucleus together against the mutual repulsion of the protons in every nucleus larger than Hydrogen’s?

Explanation:

Hi Arri, this is my question, if you cannot answer that it is fine. I hope you are doing well though :) best of luck to you when you are gone. Stay safe, well wishes

Answer:

The bigger the size of the atom, the electrons, especially the valence electrons are further away from the nucleus. The nucleus is not able to pull the electrons, that are in orbitals further away from the nucleus, towards itself and the coulombic attraction decreases.

Explanation:

Answer:

It is called a reduction-oxidation, oxide-reduction reaction, or simply as a redox reaction, any chemical reaction in which one or more electrons are transferred between the reactants

Redox battery is an example of both a Flow Battery and a two electrolyte system.In this case, it depends on two different active aqueous electrolytes of vanadium dissolved in sulfuric acid separated by a membrane at which ionic interchange takes place.

Thats my opinión though.

Answer:

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Explanation:

To Find :

The mass, in grams, of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂).

Solution :

Molecular mass of CS₂ = 76 gm/mol .

It means that mass of [tex]6.022 \times 10^{23}[/tex] molecules of CS₂ is 76 gm/mol.

Let, mass of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂) is x.

So,

[tex]x= 76\times \dfrac{1.505 \times 10^{23}}{6.022\times 10^{23}}\\\\x = 76 \times \dfrac{1.505}{6.022}\\\\x = 19 \ gm[/tex]

Therefore, the mass in gram is 19 gm.
