Chromium, cobalt, and manganese are three extremely important metals. Are these metals uniformly distributed in the lithosphere? If not, what region of the Earth is the source of these metals?

Answers

Answer 1

Answer:

No.

Explanation:

No, these metals are not uniformly distributed in the lithosphere, they are present some special regions of earth. Chromium ore is found in many places including South Africa, India, Kazakhstan and Turkey. Cobalt ore deposits are present in the regions of Congo, Canada, Australia, Zambia and Brazil. China, Africa, Australia and Gabon are the regions on the earth where manganese metal is present in large quantity.

how does atomic radius affect coulombic attraction?

Answers

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.

Is iron rusting a chemical reaction? Explain why or why not.

Answers

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.

Which of the following elements is the least reactive metal? Sodium, Rubidium, Chlorine, and Magnesium.​

Answers

First off chlorine is not a metal so you can ignore that one.

Sodium and Rubidium are in group 1 of the periodic table and Magnesium is in group 2.

Group one metals are more reactive than group two because it is harder for the group two metals to lose their 2 valence (outer most) electrons.

As you go down group 1 there is an increase in the reactivity this is because as you go down there is an increase in the atomic radius which leads to more shielding. This weakens the electrostatic forces of attraction making it easier to lose the outermost electrons, therefore they are more reactive.

Answer:

Magnesium

What would be the mass, in grams, of 1.505 x 10^23 molecules of carbon disulfide (CS2)?

Answers

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.

Explanation:

Form a bond: Each electron has a charge of 1–, and each proton has a charge of 1+. You can calculate the charge of an atom by subtracting the number of electrons from the number of protons. Move an electron from the sodium to the chlorine atom.

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

2. Chlorine has a charge of 1+ and sodium has a charge of 1-

3. Both atoms have a charge of 1+

4. Both atoms have a charge of 1-

Answers

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

What is a buffer made from?

Answers

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

What is a buffer?

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.

Why is sublimation such a critical component for the water cycle in cold climates?

Answers

The air is so dry that when it hits a snowpack, the frozen water evaporates, going directly from the ice to vapor and bypassing the liquid phase entirely. This is called sublimation, and it's a common way for snow to disappear in the arid West."

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:

El primer gas alcalino y el primer gas noble tienen el mismo número de niveles ocupados. Cierto.

La primera tierra alcalina tiene 2 e en su CEE. Cierto.

El cuarto halógeno tiene 5 electrones de valencia. Falso.

Explicación:

El primer alcalino y el primer gas noble tienen el mismo número de niveles ocupados porque el primer alcalino tiene 1 electrón y solo tiene una capa, mientras que el gas noble tiene 2 electrones y también tiene una capa. El primer alcalinotérreo tiene 2 e en su CEE debido a la presencia en el segundo grupo en la tabla periódica. El cuarto halógeno no tiene 5 electrones de valencia en su capa más externa, tiene 7 electrones en su capa más externa debido a la presencia en el grupo de siete de la tabla periódica.
