Answer:

The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collectors

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 $CCl_{4}$ < $CHCl_{3}$ < $NaNO_{3}$ .

What are the ion concentrations in a 0.12 M solution of AlCl3? A) 0.12 M Al3+ ions and 0.040 M Cl- ions B) none of the answers C

KIM [24]

Answer:

Explanation:

To answer this question, we will need to write the dissociation equation of aluminum trichloride.

AlCl3 ——-> Al3+ + 3Cl-

It can be seen that when aluminum chloride dissociates, it gives one mole of aluminum ion and three moles of the chloride ion.

From here we can see that the concentration of the aluminum chloride equals that of the aluminum ion while that of the chloride ion is thrice that of the aluminum chloride. This means we simply multiply 0.12M by 3 to get the molarity of the chloride ion while that of the aluminum ion remains the same

4.2 g of lithium (Li) reacts with 2.8 g of nitrogen (N2). Find the simplest molar ratio in which lithium reacts with nitrogen.

o-na [289]

The simplest molar ratio in which lithium reacts with nitrogen is 6 moles of lithium to 1 mol of nitrogen.

What is molar ratio?

A molar ratio examines the ratio that exist between two chemical compounds showing the amounts in moles of the compounds involved in a chemical reaction.

Molar ratio = amount of a constituent in moles ÷ total amount of all constituents in a mixture in moles

Given:

Mass of lithium (Li) = 4.2 g

Mass of nitrogen (N2) = 2.8 g

Total amount of mass = 7g

Moles = molecular weight ÷ mass of water

Moles of lithium (Li) = 4.2 ÷ 7 = 0.60 mol

Moles of nitrogen (N₂) = 2.8 ÷ 7 = 0.10 mol

Therefore, ratio Li : N₂ = 0.60 : 0.10 = 6 : 1

6 Li + N₂

The balanced equation between lithium and nitrogen, to form lithium nitride = 6 Li + N₂ → 2 Li₃N₆L i + N₂ → 2Li₃N

In summary, the simplest molar ratio in which lithium reacts with nitrogen is 6:1
