Define ionic bond dot diagram ?

Group 8 elements, generally known as noble gases, are noted for their inertness. They hardly never react with other elements, such as water, oxygen, or metals. This is due to the fact that they all have a complete outer shell of electrons. This is the most stable electron configuration possible for an atom.

Other elements, on the other hand, do not have this stable electron configuration. Instead, in order to obtain that ideal arrangement, they must acquire, lose, or share electrons. Ionic bonding is one method for doing this.

the answer for the ionic bond dot diagram for the Nacl was found to be.

PLEASE HELP ANSWER ALL PARTS!!!

Answers

Answer:

The student should have multiplied the molar mass, which was not found, by the number of moles to get an answer of 925grams of Ca(OH)2.

Please find the correct step below

Explanation:

According to the question attached, the student was asked to find the mass in grams of a 12.5mol of Ca(OH)2.

Using the formula;

mole = mass ÷ molar mass

Molar mass of Ca(OH)2 = 40 + (16 + 1)2

= 40 + 17(2)

= 40 + 34

= 74g/mol

From the above formula;

Mass in grams = mole × molar mass

Mass (g) = 12.5 × 74

Mass (g) = 925grams of Ca(OH)2.

To TWO significant figures, the measurement of 0.0255 g should be reported as

Answers

Sig Fig applies only to numbers that not zero, only except when the zero is after the the number.

How does this diagram of part of the water cycle help Sharon explain what happened to the pasta water?

Answers

Answer:

1. A

2. C

Explanation:

For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.

What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.

A is the correct answer.

for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.

C is the correct answer.

Choose the aqueous solution below with the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable.

Answers

The question is incomplete, the complete question is;

Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. 0.100 m C6H12O6 0.100 m AlCl3 0.100 m NaCl 0.100 m MgCl2 They all have the same boiling point.

Answer:

AlCl3 0.100 m

Explanation:

Let us remember that the boiling point elevation is given by;

ΔTb = Kb m i

Where;

ΔTb = boiling point elevation

Kb = boiling point constant

m = molality of the solution

i = Van't Hoff factor

We can see from the question that all the solutions possess the same molality, ΔTb now depends on the value of the Van't Hoff factor which in turn depends on the number of particles in solution.

AlCl3 yields four particles in solution, hence ΔTb is highest for AlCl3 . The solution having the highest value of ΔTb also has the highest boiling point.

Explanation:

Atoms are said to be electrically neutral when they have the same number of protons and electrons.

Now, Nitrogen atom has a mass number of 14 and an atomic number of 7. This means that it has 7 number of protons and 7 number of electrons.

From the definition of electrically neutral atoms, it's clear that nitrogen falls into that category.

Explanation: I like math. Pls mark brainliest.

The two numbers presented in the options, B, C, and D give a sum of 445.2 grams. So the correct options are B, C, and D.

What are significant figures?

The number that is given as digits is established using significant figures. A significant depiction of numbers is carried by these digits. Frequently, significant numbers are employed in place of figures. By counting all of the values beginning with the first non-zero digit on the left, we may determine the number of significant digits. 13.56, for instance, has four significant digits.

The crucial or key digits that accurately represent the meaning of a certain number are known as the significant figures of that number. 7.864 contains four significant digits, for instance. These huge amounts give the accuracy of the numbers. Additionally, they are known as important digits.

Therefore, the correct options are B, C, and D.

The given reaction is an example of displacement reaction. Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen.

What is displacement reaction?

Displacement reactions are a kind of reactions where one element or group is displaced with other element or group. There are both single displacement and double displacement reaction.

The reaction of sulfur oxide with metallic copper producing copper oxide and copper sulphide is an example of single displacement reaction. The prior reaction for this is the combination of sulfur and oxygen.

Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen. Thus each is reacting in 1 :1 ratio and giving the oxide of sulfur.
