Which of the following is a property of bases?

B. Feels slippery

This is most likely the Chemical Properties of Bases

The Chemical Properties of Bases include:

- Bases change the colour of litmus from red to blue.

- They are bitter in taste.

- Bases lose their basicity when mixed with acids.

- Bases react with acids to form salt and water. This process is called Neutralisation Reaction(Read).

- They can conduct electricity.

- Bases feel slippery or soapy.

- Some bases are great conductors of electricity.

- Bases like sodium hydroxide, potassium hydroxide, etc are used as electrolytes.

- Alkalis are bases that produce hydroxyl ions (OH-) when mixed with water.

- Strong alkalis are highly corrosive in nature whereas other alkalis are mildly corrosive.

- The pH value of bases ranges from 8-14.
Alkalis and ammonium salts produce ammonia.

- Hydrogen gas is evolved when metals react with a base.

- Bases are classified on the basis of strength, concentration and acidity.

- The different kinds of acids are strong base acid, weak base acid, concentrated base, dilute base, monoacidic base, diacidic base and triacidic base.

Consider the Van der Vaals equation of state: (????+????????????)(????−????)=???????????? where p is pressure, V is volume, n is

yanalaym [24]

Answer:

Units of a = $\frac{atm\ L^2}{mol^2}$

Units of b = $\frac{L}{mol}$

Explanation:

The Van der Waal's equation is:-

$\left(P+\frac{an^2}{V^2}\right)\left(V-nb\right)=nRT$

Where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value

a and b are van der Waal's constant

If pressure is taken in atm and volume in L. So,

$P+\frac{an^2}{V^2}$ represents the pressure correction term. Then,

Units of a = $\frac{atm\ L^2}{mol^2}$

$V-nb$ represents the volume correction term. Then,

Units of b = $\frac{L}{mol}$

Why is the classification species not considered a group? (1 point)

vitfil [10]

Each species is a separate type of organism.

A species is a group of creatures that share similar traits. The same species of organisms are capable of sexual reproduction as well as interbreeding and producing fertile offspring. It is a fundamental unit of taxonomy and classification.
The system is divided into seven categories: Kingdom, Phylum or Division, Class, Order, Family, Genus, and Species. Kingdom is the most inclusive category.
In a group, many types of an organism can be included even if they do not share the same traits. But species is a group of organisms that share similar traits.
For example, human beings are species as they are all alike in physical features, way of reproduction, etc. But the animal is considered a group because it included a variety of living beings.

Therefore, Each species is not considered a group.
