A solution is a homogenous mixture of solute and solvent. there are different types of solutions. a carbonated drink is an examp

le of a solution where the solute is a gas and the solvent is a liquid. sugar crystals dissolved in water is an example of a solution where the solute is a solid and the solvent is liquid. acetic acid is miscible in water, forming a solution commonly known as vinegar. in this case, both the solute and the solvent are liquids. the solubility of solute in a solvent depends on various parameters, such as temperature, pressure, the nature of the solute, and the nature of the solvent. considering these parameters, identify the statements that are correct for the solubility of a solute in a solvent. check all that apply. hints check all that apply. table salt dissolves in water to form a solution. gases are readily soluble in water at higher temperatures. ethanol and hexane are miscible. zinc sulfate is soluble in water. carbon dioxide gas will be more soluble in water when the partial pressure is high.

The following statements are correct:
ZINC SULPHATE ARE SOLUBLE IN WATER.
TABLE SALT DISSOLVES IN WATER TO FORM A SOLUTION.

Answer:

The correct statements are:  

1. Table salt is soluble in water, table salt (NaCl) get dissociate in water as NaCl = Na+ + Cl-.  

2. Zinc sulfate is also soluble in water, as zinc sulfate gets dissociate in water as ZnSO4 = Zn2+ + SO42-.  

3. The solubility of carbon dioxide gas in water increases with partial pressure and drops down with the drop in partial pressure.  

The incorrect statements are:  

1. Gases do not get easily soluble in water at high temperatures. The higher kinetic energy makes more motion in the molecules of gas which dissociate intermolecular bonds and escape from solution.  

2. Ethanol and hexane are not miscible, as ethanol is hydrophilic due to the presence of -Oh group and hexane is hydrophobic. So, these compounds will not mix.

What's the IUPAC name pf this compound? CH3-CH-CH2-CH-CHO | | CH3 CL
Svetradugi [14.3K]

Answer:

2-chloro-4-methylpentanal.

Explanation:

Hello there!

In this case, according to the chemical compound:

CH3-CH-CH2-CH-CHO

          |              |

        CH3        Cl

We can see the main functional group is an starting carbonyl, which means this is an aldehyde. Moreover, we can see a Cl-substituent on the second carbon and a methyl substituent on the fourth carbon. Therefore, the IUPAC name turns out: 2-chloro-4-methylpentanal.

Best regards!
