Why are ionic compounds solids

Chemistry
2 answers:
enot [183]3 years ago

Answer: The crystal structure of ionic compounds is strong and rigid. It takes a lot of energy to break all those ionic bonds. As a result, ionic compounds are solids with high melting and boiling points.

Answer:

Ionic compounds are solids with high melting and boiling points.

Explanation:

The crystal structure of these ionic compounds are very strong and rigid. It will take a lot of energy to break all of those ionic bonds. The super strong bonds between their oppositely charged ions pre-lock them into postion in their crystal.

What is the chemical formula for 8.6 mol of sulfur and 3.42 mol of phosphorus
adell [148]

The chemical formula for the compound containing 8.6 mol of sulfur and 3.42 mol of phosphorus is P₂S₅

<h3>How do I determine the formula of the compound?</h3>

From the question given above, the following data were obatined:

  • Sulphur (S) = 8.6 moles
  • Phosphorus (P) = 3.42 mole
  • Chemical formula =?

The chemical formula of the compound can be obtained as follow:

Divide by their molar mass

S = 8.6 / 32 = 0.26875

P = 3.42 / 31 = 0.11032

Divide by the smallest

S = 0.26875 / 0.11032 = 2.44

P = 0.11032 / 0.11032 = 1

Multiply by 2 to express in whole number

S = 2.44 × 2 = 5

P = 1 × 2 = 2

Thus, the chemical formula is P₂S₅

A change in which property of light will have no effect on whether or not the photoelectric effect occurs?
lorasvet [3.4K]

Answer:

intensity

Explanation:

Intensity has no affect on whether or not the photoelectric effect occurs. The determining property is frequency and since frequency and wavelength are inversely proportional, wavelength matters as well

Which answer below correctly identifies the type of change and the explanation for the boiling of water?
Lynna [10]

physical change because even though gas formation was observed, the water was undergoing a  state change, which means that its original properties  are preserved

Explanation:

The boiling of water is a physical change because the original properties of the water is preserved.

  • A physical change is the one that alters the physical properties of matter.
  • This kind of change is easily reversible as the water can be cooled back.
  • No new kinds of matter is produced in this kind of change .
  • The molecules of the matter still retains their property after.

During the boiling of water, intermolecular bonds called hydrogen bonds between the water molecules are broken. This makes the individual molecules free.
