Identify the major ions present in an aqueous lioh solution

Chemistry
2 answers:
irakobra [83]3 years ago
7 0

<u>Answer:</u> The major ions present in aqueous LiOH solution is lithium ions and hydroxide ions.

<u>Explanation:</u>

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

The chemical equation for the ionization of LiOH solution follows:

LiOH(aq.)\rightarrow Li^+(aq.)+OH^-(aq.)

By Stoichiometry of the reaction:

1 mole of lithium hydroxide produces 1 mole of lithium ions and 1 mole of hydroxide ions

Hence, the major ions present in aqueous LiOH solution is lithium ions and hydroxide ions.

When you dissolve an ionic compound into water, the have a tendency to separate from each other. They're still chemically the samething.

LiOH is an ionic compound. Lithium is positive and "borrows" the hydroxide's negative charge to be neutral & vice-versa. When LiOH is dissolved in water the Lithium and the hydroxide separate into their respective forms, also known as ions.

So, LiOH dissolves to become these ions in solution= Li+ and OH-
(the plus and minus represent their charges).

Hope that helps!

How does changing the ratio of nitrogen atoms and oxygen atoms change the compounds
Reptile [31]

Answer:

Explanation:

Compounds consist of atoms of different elements. In compound the atoms are present in fixed proportion. By changing the proportion compound will changed. For example,

Nitrogen and oxygen reacted to form the compound. By changing the proportion both will form different compound.

NO₂

Nitrogen dioxide consist of one atom of nitrogen and two atoms of oxygen. Their ration is 1 :2

NO

In nitric oxide one atom of oxygen and one atom of nitrogen are present.

Their ratio is 1 : 1.

N₂O

Nitrous oxide consist of two nitrogen atoms and one oxygen. Their ratio is

2 : 1

N₂O₄

Dinitrogen tetroxide consist of two nitrogen atoms and four oxygen atoms. Their ratio will written as 2 : 4

N₂O₅

Dinitrogen pentoxide consist of two nitrogen atoms and five oxygen atoms. Their ratio will written as 2 : 5

It can be seen that by changing the ratio of atoms compounds are changed.

A fruit-and-oatmeal bar contains 142 nutritional Calories. Convert this energy to calories
madreJ [45]

Answer:

a fruit and oatmeal bar contains 142000 calories.

A nutritional calorie, or kilocalorie, is equal to 1000 calories.

E = 142 kcal · 1000 cal/kcal.

E = 142 000 cal.

Calorie (cal), or small calorie, is the amount of energy needed to heat one gram of water by one degree Celsius.

One small calorie is approximately 4.2 joules.

A calorie is a unit of energy.

Which option states the principle behind the law of conservation of mass and the law of conservation of energy?
jeka94

Answer:

A

Explanation:

The law of conservation of mass states that matter can never be created nor destroyed but can be converted from one form to another.

The law of conservation of energy posits that energy cannot be created nor destroyed but can be converted from one form to another.

These laws are the basic laws of existence. Although the laws have been adjusted, they still form the basic principle behind several scientific laws and are responsible for a whole lot of scientific advancements.

While the first law focuses on matter and the content of matter in a body, the second law basically focuses on energy. The second law serves to support the inter convertibility behind the several forms or types of energy.

For example, to do many useful work at home, it is found that energy is converted from its electric form to say heat in an electric iron to press our clothes.

Also, the first law is a fundamental principle useful in the balancing of our chemical equations.
