Explanation:

Wind turbine are efficient only in certain areas it is a problem with using wind turbines to produce energy.

Wind turbine convert the wind energy into the electricity. It is a power generating device that converts the kinetic energy in to electrical energy.

Now lets check all option one by one:

Option (A): Wind turbines are efficient only in certain areas it is a problem with using wind turbines to produce energy because the flow of air from areas of high pressure towards the lower pressure.

So, it is correct option.

Option (B): Wind turbines occupy a lot of space to work.

So, it is incorrect option.

Option (C): Wind turbines produce a large amount of energy is not a problem.

So, it is incorrect option.

Option (D): Wind turbines does not create a pollution or it does not pollute the air or water.

So, it is incorrect option.

Thus, we can say that Wind turbines are efficient only in certain areas it is a problem with using wind turbines to produce energy because the flow of air from areas of high pressure towards the lower pressure.

Answer:

D

Explanation:

Answer:

C) gold - zinc - magnesium - lithium

Answer:

Calcium

Explanation:

is a silver-gray metal which takes its name from the Latin word calx, which means lime. It is the fifth most abundant element in the earth's crust and is widely distributed as limestone (CaCO3), quicklime (CaO) and calcium fluoride.

Alkaline earth metals are present on the left of the periodic table. Therefore, calcium is the alkaline earth metal is the components of quick lime​.

Metals are those elements which is hard, conduct electricity, ductile, lustrous and malleable.

The properties of metals are:

1.Since metals have free electrons that's why they can conduct electricity

2. Since atoms in metals are very closely packed in a definite crystal so these are solid. It is not brittle that is it can not be broken down easily

3. It does not react with water easily.

4.It is denser than water hence it sink in water.

The formula for quick lime is quicklime (CaO). The alkaline earth metal that is component of quick lime is calcium Ca. Quick lime is used in white washing.

Therefore, calcium is the alkaline earth metal is the components of quick lime​.

Answer:

Yes, pure NaCl will precipitate out of the solution

Explanation:

The parameters of the NaCl solution and HCl mixture are;

The saturation of the NaCl solution = Saturated solution

The mass concentration of the NaCl solution = 317 g/L

The volume of the HCl added = 10 mL

The concentration of the HCl added = 13.0 M HCl

The volume of the saturated NaCl solution = 0.2 L

The molar mass of NaCl = 58.44 g/mol

The number of moles of NaCl per liter = (317 g/L)/(58.44 g/mol) = 7925/1461 moles ≈ 5.42 moles

The ionization of the molecules in solution are;

HCl (aq) + H₂O (l) → H₃O⁺ (aq) + Cl⁻ (aq)

NaCl (s) ↔ Na⁺ (aq) + Cl⁻ (aq)

The number of moles of the Cl⁻ ion from the HCl is 13 moles per liter, the number of moles of Cl⁻ ion from the saturated solution of NaCl is approximately 5.42 moles, therefore, ionic product I.P. of the solution of Cl⁻ ions is larger than the solubility product of the solution, [tex]K_{sp}[/tex] of the NaCl and according to Le C h a t e l i e r's principle, NaCl will precipitate out of the solution

Answer:

Answer is 1

Explanation:

Answer:

Calculate the number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4

Explanation:

lions only eat meat, antelopes are prey

Answer:

See answer below

Explanation:

In this case, you just need to use any acid you want (Like HCl, or H₂SO₄) to do this exercise.

You are given a sample of what you have to do which is:

Acid + metal ------> Salt + hydrogen

As you can see, an acid like the ones I wrote above, have hydrogen atoms, so you should put the hydrogen there. As for the part of salt, you just need to draw the corresponding salt that is formed when the acid reacts with the metal, and write it's name.

Let's do all three equations for you to a better understanding. For all the given examples, I will use HCl as acid, and i will explain one reaction cause the other two reactions happens the same thing, only with a different metal.

1. 2HCl + Zn ------> ZnCl₂ + H₂

As you can see, we just have a displacement reaction where the metal displaces the position of the hydrogen to form the salt and the hydrogen leaves the molecule as a gaseous molecule. Written in words it would be:

Hydrochloric acid + Zinc ----> Zinc chloride + hydrogen

2. 2HCl + Pb -------> PbCl₂ + H₂

Hydrochloric acid + lead ------> Lead (II) chloride + hydrogen

3. 2HCl + Fe -------> FeCl₂ + H₂

Hydrochloric acid + iron ------> Iron (II) chloride + hydrogen

Answer:

Answer: If the atom loses 2 electrons, the net charge on the atom will be 2+

If the atom gains 4 electrons, the net charge on the atom will be 4-

Explanation:

An atom is smallest unit of a matter or substance.It consist of three subatomic particles : electrons, protons, neutrons.

Protons are positively charged, neutrons are neutral and both are located in nucleus where mass of an atom is concentrated.

Electrons are negatively charged and are located outside the nucleus where they orbit in different energy levels around the nucleus.

In an atom, when electrons are lost, the atom gains a positive charge and forms cation. In an atom, when electrons are gained, the atom occupies a negative charge and forms anion.

Thus an atom with 9 electrons and 9 protons will be electrically neutral.

On losing 2 electrons, there will be 7 electrons and 9 protons will have 2+ charge.On gaining 4 electrons, there will be 13 electrons and 9 protons will have 4- charge.

Explanation:

Answer:

How many atoms are in 6.2 moles of aluminum? I mol = 6.02X1023 atoms so 6.2 mol = 6.2x (6.02x1025) = 3.73 x1024 atoms of Aluminum

There are approximately 3.86528 × 10²⁴ atoms of aluminum (Al) in 6.4 mol of aluminum.

To determine the number of atoms of aluminum (Al) in 6.4 mol, we use Avogadro's number, which states that 1 mole of any substance contains 6.022 × 10²³ particles (atoms, molecules, or ions).

Given that 6.4 mol of aluminum is provided, we can use Avogadro's number to calculate the number of atoms:

Number of atoms = (6.4 mol) × (6.022 × 10²³ atoms/mol)

Calculating the multiplication, we find:

Number of atoms = 3.86528 × 10²⁴ atoms

Therefore, there are approximately 3.86528 × 10²⁴ atoms of aluminum (Al) in 6.4 mol of aluminum.

This calculation is based on the fact that 1 mole of aluminum contains Avogadro's number of aluminum atoms. The molar quantity allows us to convert between the mass of a substance and the number of atoms or molecules present.

Avogadro's number is a fundamental constant in chemistry that relates the mass of a substance to the number of particles it contains. It is approximately 6.022 × 10²³ particles per mole. By using this conversion factor, we can determine the number of atoms present in a given amount of substance.
