Fe + Cl2 → FeCl3, what coefficients would balance the equation?
3,2,2
1,1,1
2,3,2
4,2,2​

Answers

Answer 1

The coefficients that will balance the equation will be 2,3,2.

Balancing chemical equation

For a balanced equation, the number of atoms of each element on the reactant side must be equal to those of the product side.

Thus, the balanced equation of the reaction will be:

2Fe + 3Cl2 → 2FeCl3

Consequently, the coefficients of the balanced equation are 2,3,2.

lead has a density of 11.4 g/cm^3 . what is the density in kilograms per cubic meter in scientific notation?​

Answers

Answer:

d = 11400 kg/m³

Explanation:

The density of lead is 11.4 g/cm³

We need to convert the density in kg/m³ in scientific notation.

We know that,

1 kg = 1000 g

1 cm = (1/100) m = 0.01 m

Density,

[tex]d=11.4\ \dfrac{g}{cm^3}\\\\=11.4\times \dfrac{(\dfrac{1}{1000})\ kg}{(0.01\ m)^3}\\\\=11400\ kg/m^3[/tex]

So, the density of the lead is 11400 kg/m³.

The density of this material is 2 g/cm^3.There are 24 cm^3.
What is the total mass?

Answers

Answer:

[tex]\boxed {\tt 48 \ grams}[/tex]

Explanation:

Mass can be found by multiplying the density by the volume.

[tex]m=d*v[/tex]

The density is 2 grams per cubic centimeter.

The volume is 24 cubic centimeter.

[tex]d= 2 \ g/cm^3 \\v=24 \ cm^3[/tex]

Substitute the values into the formula.

[tex]m= 2 \ g/cm^3 *24 \ cm^3[/tex]

Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.

[tex]m= 2 \ g * 24[/tex]

[tex]m= 48 \ g[/tex]

The mass of the material is 48 grams.

If 6.5 g of magnesium ribbon reacts completely
with hydrochloric acid, how many grams of
hydrogen gas would be liberated? Mg , + 2HC1(ag)
→ MgC1 + H, [H = 1.0, Mg = 24.0]

Answers

Answer:

The mass of hydrogen gas liberated is 0.6 g.

Explanation:

Given data:

Mass of Mg = 6.5 g

Mass of hydrogen gas liberated = ?

Solution:

Chemical equation:

Mg + 2HCl     →    MgCl₂ + H₂

Now we will calculate the number of moles of Mg.

Number of moles = mass / molar mass

Number of moles = 6.5 g/ 24 g/mol

Number of moles = 0.3 mol

Now we will compare the moles of Mg with hydrogen gas.

            Mg         :          H₂

             1           :           1

             0.3       :        0.3

Mass of H₂:

Mass = number of moles × molar mass

Mass = 0.3 mol × 2 g/mol

Mass = 0.6 g

What types of epithelial cells would you expect to find in an area of the body where diffusion of nutrients needs to occur?
1) Cuboidal
2) Columnar
3) Squamous​

Answers

Answer: C. Squamous

Explanation:

I got it right on my test...lol

The type of epithelial cells that would be found in an area of the body where diffusion of nutrients needs to occur is squamous.

Epithelial cells refer to the cells that are vital in the lining of the surface of the body. Epithelial cells can be found on the blood vessels, skin, and urinary tract.

It should be noted that epithelial cells are important as they act as a protective barrier and help in stopping viruses from getting inside the human body.

It should be noted that squamous can be found in an area of the body where diffusion of nutrients needs to occur. They're flat cells and they are usually thin and resembles the scale of fishes.

In conclusion, squamous can be found on the surface of the skin.

Explanation:

Chemical reaction or chemical change is characterized by gas  evolution, precipitate formation and  the color changes.

What is a chemical change?

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

how atoms differ from others, pls is so urgent

Answers

Answer:

There are more than a hundred different atoms, but each element contains only one kind of atom.

Atoms are what make one element different from another.

So what makes one atom different from another?

The Greeks thought atoms could not be divided into anything smaller but they were wrong! Every atom can be divided into three different components - protons, neutrons and electrons.

The nucleus, or centre of an atom, is made of protons, (which have a positive electrical charge) and neutrons, which are neutral (in other words, they have no charge).

Electrons, which have a negative charge, move around the centre of the atom.

Normally, the number of electrons is equal to the number of protons, which makes atoms electrically neutral.

The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number. Oxygen atoms have 8 protons. So the atomic number of oxygen is 8.

All the elements in the universe are arranged according to their atomic number in the periodic table.

Atomic mass

If you add together the number of protons (or atomic number) and the number of neutrons in the nucleus of an atom, you can calculate the mass of the atom. Helium (He), atomic number two, has two protons and two neutrons. So the mass number for Helium is 4.

Isotopes

Atoms with the same number of protons but different numbers of neutrons are called isotopes. Uranium-238 and uranium -235 are two different isotopes of uranium. Uranium- 238 has a mass number of 238. Uranium-235 has a mass number of 235. So uranium-238 has more neutrons than uranium-235. But they are still both atoms of uranium because they have the same number of protons.

how to draw Bohr Model of Phosphorus?? ​

Answers

Answer:

look at the image below

Explanation:

The Bohr model of phosphorus depicts 15 electrons in different energy levels, with the nucleus at the center.

Two electrons are present in the first energy level, eight electrons are present in the second and five electrons are present in the third. The electron configuration of phosphorus, which is [tex]1s^2 2s^2 2p^6 3s^2 3p^3[/tex], matches this distribution.

The formula [tex]2n^2[/tex], where n is the energy level number, determines the maximum number of electrons in each energy level. Therefore, the first energy level can accommodate only two electrons, the second energy level up to eight, and the third energy level up to eighteen.

Susan made observations about outside events she noticed throughout the day. The day began with rain. Susan saw puddles on the road. The rain stopped and the sun began to shine. The puddles disappeared. Later, clouds began to form in the sky. How do the parts of the water cycle relate to the events that Susan saw?

Answers

Answer:

Rainfall - precipitation

disappeared puddles - evaporation

cloud formation - condensation

Explanation:

Rainfall that is observed by the Susan is the precipitation of the water cycle in which the water vapor that was condensed become heavy and form droplets of water and fall from sky to the earth surface.

Puddles that formed due to rainfall are the collection of water in the water cycle which is evaporated (process: evaporation) into the atmosphere n the form of water vapor which condensed to form clouds.
