Which of the following is the correct Lewis Dot Structure for MgBr2?
PHOTO ABOVE

Answer:

30%

Explanation:

As the formula for finding concentration

= (mass of solute/mass of solution)×100

= (30/100)×100

= 0.3×100

= 30%

The concentration is 30%.

As the formula for finding concentration

= (mass of solute/mass of solution)×100

= (30/100)×100

= 0.3×100

= 30%

The amount of a substance, such as salt, is in a positive amount of tissue or liquid, along with blood. A substance turns into more concentrated whilst much less water is present.

Answer:

Explanation:

The percentage error of a certain measurement can be found by using the formula

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual density = 0.95 g/mL

error = 0.95 - 0.56 = 0.39

So we have

[tex]p(\%) = \frac{0.39}{0.95} \times 100 \\ = 41.0526315...[/tex]

We have the final answer as

Answer:

The correct answer is A.

Explanation:

The acids with hydrogen atoms in them are the ones that dissolve best in water and when they do, they get diluted, raising their pH level by releasing hydrogen ions (H+) into the solutions.

So when acids get dissolved in water, positively charged hydrogen atoms are released.

The answer is A.

Explanation:

Answer:

B - The atoms form a bond with a bond length of 75 pm

From the potential energy diagram of shown, we can infer that the atoms form a bond with a bond length of 75 pm.

When atoms are far away from each other, there exists no interaction whatsoever between the atoms.

However, as the atoms draw closer to each other, the potential energy diagram begins to shift towards an energy minima as we can see from the potential energy diagram.

As the system continues to tend towards this minima, the distance between the atoms decreases. The distance at which the two atoms have the lowest energy is called the bond length.

For this system, such a bond length occurs at 75pm as we can see from the diagram.

c.

Explanation:

One of the main differences between an atom and an element is that an atom can be combined but an element cannot be combined. There are many combinations of atoms that make up different gases, liquids, and solids each with a unique makup. For example, water is made up of two hydrogen atoms and one oxygen atom (H20). Elements are made up of only the same type of atom. For example, the element Hydrogen can only contain hydrogen atoms, while the element Carbon can only contain carbon atoms.

Answer:

D. The net electrical charge of the Earth.

Explanation:

I remember from middle school. The other three options affect the gravitational force.

The gravitational force between the earth and the sun is dependent on the mass of these two objects as well as the distance between the earth and the sun. Thus, option D is the correct answer.

Gravitational pull is referred as a force of attraction beared by the planetary objects. Gravity is responsible for the revolution of planets around the sun in their fixed orbits.

Gravitational pull is important as it keeps the earth revolving around the sun from a safe distance. It holds the earth in position and thus supports the life on earth. Gravity is responsible for optimum atmosphere on earth.

The formation of celestial bodies is also under the influence of gravitational pull. Gravitational force thus is consired as a fundamental force that govers all the celestial bodies.

Gravitational pull is therefore important for the life on earth.

Answer:

In atomic physics and quantum chemistry , the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6, using the notation explained below.

Explanation:

i found it on google

Answer:

To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.

Explanation:

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.

Answer:

The volume of stone is 5cm³.

Explanation:

Given data:

Volume of water = 30 cm³

Volume of water and stone = 35 cm³

Volume of stone was 5 cm³ = true or false

Solution:

To check weather the given volume of stone is true or not we have to calculate the volume of stone from given data.

Volume of stone = (volume of water + stone ) - volume of water

Now we will put the values.

Volume of stone =  35 cm³ - 30 cm³

Volume of stone = 5 cm³

Thus the given value is true. The volume of stone is 5cm³.
