Answer:

d. ion pairing

Explanation:

  • The measure of the effect of a solute upon the colligative properties of a solution is known as the Van't Hoff factor.
  • Mathematically, the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass is the Van't Hoff factor.
  • If we consider the electrolytes than the Van't Hoff factor should be equal to the number of discrete ions in a formula unit of the substance, however, this is not true and the van't Hoff factor is always less than the expected value as ion-pairing takes place in the solutions.
  • Ion pairing takes place when ions of opposite electrical charge come together in solution and form a distinct chemical entity.

Answer:

The correct answer is option d. "ion pairing".

Explanation:

The van't Hoff factor is defined as the ratio between the actual concentration of particles when are in a dissolved state in comparison to the theoretical concentration calculated from its mass. The observed van't Hoff factor for an electrolyte is less than the expected factor because of the ion pairing effect. Ion pairing is the association of ions because of having opposite charges. When ion pairing takes place in a solution, two ions association would apparently be one, which reduces the observed van't Hoff factor in comparison to the theoretical.

Explain ONE similarity and ONE difference between water borne and water washed diseases ​
eimsori [14]
Water-borne diseases, including cholera, typhoid, and dysentery, are caused by drinking water containing infectious viruses or bacteria, which often come from human or animal waste. Water-washed diseases, such as skin and eye infections, are caused by lack of clean water for washing.

A student is measuring the mass of 25 beakers. Each beaker has a mass of 48.73 g. What is the total mass of all 25 beakers in ki
Rainbow [258]
48.73g to kg =48.73*1000
                   =0.04873kg
total mass=0.0473kg*25
               =1.21825kg

Which the most inclusive taxonomic grouping a)order b) species c) genus d) kingdom
zimovet [89]

The correct answer is d) kingdom.

Taxonomy is the branch of biology which deals in categorizing and naming of species. The modern taxonomic classification system consists of the eight taxonomic groups. These are Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. The domain is the most inclusive of the all taxonomic groups and species is the least inclusive.  It is because every different species has a unique features. In this question domain is not in the option, thus Kingdom is the correct answer As it includes different Phylum, Class, Order, Family, Genus, and Species.
