There are two reasons that account for the change in concentration. One is by the physical change and second is by the chemical change. The physical change refers to the mixture of the two compounds. The concentration is the amount of that certain substance to the whole mixture. Since the mixture increases because you add them up, the concentration decreases. Second, these compounds react with each other once they interact. Hence, their amounts would be consumed in order to produce the products.

Which is the term for an ion that has more protons than electrons
murzikaleks [220]

Answer:

The correct answer is cation. See the explanation below, please.

Explanation:

An atom with a net charge, either positive or negative, is called an ion. In the event that an atom loses an electron (or more), that is, it will have more protons than electrons, and its net charge will be positive, it will be called cation. In the opposite direction, if an atom gains electrons, it will have a negative net charge, called anion.

<h2>CH_3CH_2OH  →  CH_3CHO </h2>

Explanation:

Ethanol can be oxidized to ethanal or acetaldehyde which is further oxidized to acid that is acetic acid.

CH_3CH_2OH→  CH_3CHO [oxidation by loss of hydrogen]

  • An oxidizing agent potassium dichromate(VI) solution is used to remove the hydrogen from the ethanol.  
  • An oxidizing agent used along with dilute sulphuric acid for acidification.

Acetaldehyde can also be reduced back to ethanol again by adding hydrogen to it by using a reducing agent that is sodium tetrahydro borate, NaBH4.

  • The oxidation of aldehydes to carboxylic acids can be done by the two-step process.  
  • In the first step, one molecule of water is added in the presence of a catalyst that is acidic.
  • There is a generation of a hydrate. (geminal 1,1-diol).

     CH_3CHO  →  CH_3CH_2COOH [reduction by the gain of electrons]

Here, the oxidizing agent used isCr_3O in the presence of acetone.
