Answer: electron donor.

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydronium ions (H_3O^+) in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

NH_3+H^+\rightarrow NH_4^+

Here NH_3 acts as lewis base and H^+act as lewis acid.

Thus lewis base is defined as an electron pair donor.

When a writer uses “common knowledge” in an essay, why does it NOT require a citation nor is it considered plagiarism?
krek1111 [17]
Plagiarism is when you just copy exactly what someone else says, without their permission, or without citing where you got it from. 
Common knowledge should be your own words. unless you take it from somewhere else, it doesnt need anything.

Explain the term contact force and give examples​
aliya0001 [1]

Answer & Explanation:

In physics, a contact force is a force that acts at the point of contact between two objects, in contrast to body forces. Contact forces are described by Newton's laws of motion, as with all other forces in dynamics. Contact force is the force in which an object comes in contact with another object. Contact forces are also direct forces. Contact forces are ubiquitous and are responsible for most visible interactions between macroscopic collections of matter. Pushing a car up a hill or kicking a ball or pushing a desk across a room are some of the everyday examples where contact forces are at work. In the first case the force is continuously applied by the person on the car, while in the second case the force is delivered in a short impulse.
