Question 7
a reaction between an acid and a base that produces a salt and water is a( reaction.
a)neutralization
b)synthesis
c)decomposition
d)endpoint

Neutralization

Explanation:

Neutralization, there is nothing much to add. Neutralization is the reaction of an acid and a base. A typical acid is HA and a typical base BOH the reaction is:

HA  +  BOH  ->  H2O + BA

H2O is water

BA is the salt

A reaction between an acid and a base that produces a salt and water is a neutralization reaction. Hence the answer is option A.

Explanation:

A neutralization reaction is defined as when a chemical utilize the other chemical during the course of reaction. In this case the acid utilizes the base and the base neutralizes the acid. During the course of reaction the salt is formed and the salt is deposited in the base of the container.

Acid can turn blue litmus into red whereas a base can turn red litmus paper into blue. According to the pH value of acid is defined as whose value is is less than 7 and a base is defined as whose value is more than 7 up to 14.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
