Define and then describe the difference between a polar covalent bond, nonpolar covalent bond and ionic bond.
Romashka [77]
Polar covalent bond-  a bond where atoms are unevenly shared due to a larger difference in electronegativity of the bonded elements.

Non-polar covalent bond- These are bonds between elements with a low difference in electronegativity. Electrons are shared equally in these bonds between the elements.

Ionic bonds- have such  large difference in electronegativity that they take/give electrons to the element they are bonded to. They do not share electrons at all. Bonds between a non-metal and a metal.

Please answer, please answer please answer please answer<br>my last 2 chemistry question. ​
scoundrel [369]

Answer:

1. filtration and evaporation

2. i) water is added to the sand and salt mixture

ii) then the mixture is filtrated and so the sand and the salt water was seperated

iii) the salt water is heated with the help of burner until the water gets evaporated

iv) after the water gets evaporated, the salt is remained in the container

3. observation:

  • on adding water to the mixture, the salt is completely dissolved in the water
  • when filtrated the sand is seperated from the salt water
  • now the salt water when heated with the burner until the evaporation, the water is evaporated
  • the salt is precipitated and remained in the container

4. cautions:

  • while using the burner, we should be cautious with fire
  • the container that is heated should be holded with the help of a cloth to avoid heat

If one benzene molecule is placed in water, the total entropy of the water + benzene system:___________
valkas [14]

Answer:

d) increases

Explanation:

Benzene is an aromatic hydrocarbon which is obtained from the destructive distillation of coal. It is a colourless volatile liquid with a sweet smell. It boils ar 80° C (353 K) and freezes at 5°C (2278 K). It is insoluble in water but mixes in all proportions with ethanol, ethoxyethane and methylbenzene. The reason which benzene is insoluble in water is that benzene is a non-polar compound and water is polar, meanwhile only "like dissolves like". So, when the benzene molecule is placed in water. There will be distortion and disturbance between the benzene molecule and the water. Thus, the particle of each molecule will be distant from each other. This state results to change in the entropy of the system as the entropy of the system increases.

RSB [31]
  Any type of electromagnetic energy's wavelengths that are shorter than a type of electromagnetic energy's wavelengths is to the left of that type of electromagnetic energy on the diagram.  Hence, the wavelength of a type of energy decreases as you progress to the left on the diagram and left of the green light (in the visible spectrum).
