which of the following features provides evidence of a glacier and establishes its directed of movement?

Chemistry

mariarad [96]2 years ago
5 0

Answer:

The pressure from the weight of the glacier generates a layer of water that helps the ice glacier move downslope. This process is called basal sliding. Also, the glacier begins to move under its own weight. The glacier is so heavy and exerts so much pressure that the firn and snow melt without any increase in temperature.

Which of the following choices has the compounds correctly arranged in order of increasing solubility in water? (least soluble t
larisa86 [58]

Answer: Option (d) is the correct answer.

Explanation:

As it is known that like dissolves like. So, water being a polar compound is able to dissolve only polar compounds.

Hence, a compound that is ionic or polar in nature will readily dissolve in water. Whereas non-polar compounds will be insoluble in water.

As CCl_{4} is a non-polar compound. Hence, it is insoluble in water.

On the other hand, CHCl_{3} is a polar compound due to difference in electronegativity of chlorine and carbon atom there will be development of partial charges. Hence, there will be dipole-dipole forces existing between them.

Whereas NaNO_{3} is an ionic compound and it will readily dissociate into ions when dissolved in water. Also, there will be ion-dipole interactions between sodium and nitrate ions.

Hence, NaNO_{3} will readily dissolve in water.

Thus, we can conclude that the compounds correctly arranged in order of increasing solubility in water are CCl_{4} < CHCl_{3} < NaNO_{3}.

Look at the diagram. Which shows the correct arrangement of electrons in water?
mariarad [96]

Answer:

Option 4

Explanation:

In water molecule, oxygen has -2 charge on it while the hydrogen has +1 charge and one atom of oxygen combines with two hydrogen atoms. A hydrogen need only two electrons to complete its octet (one electron is its own the second electron is shared by oxygen) and a oxygen needs 8 electrons (It has six of its own and two are shared by two hydrogen atom).

Hence, option 4 is correct

How to tell if a compound is ionic or molecular?
zhenek [66]
<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds will contain both metals and non-metals, or at least one polyatomic ion. *Acids will always include the (aq) symbol beside the formula, and the name will include the word acid.</span>
