Answer:
A neutralization reaction between an acid and a metal hydroxide produces salt and water.
Explanation:
In a neutralization reaction, an acid and a base are combined according to the following example (hydrochloric acid and sodium hydroxide):
HCl + NaOH ---> H20 + NaCl
They are generated as products: water and a salt, in this case sodium chloride.
When an entire species perishes the species becomes extinct.
Answer: The correct answer is C.
Explanation: Frictional force is the contact force which resists the motion of one surface on another.
Mathematically,

where,
f = frictional force
= Coefficient of friction
N = normal force acting on a body
We need to find the ratio of force of sliding friction ( which is a type of frictional force) and the normal force acting on an object. This will be equal to coefficient of friction.

Answer:
The rooe of rainforests in the water cycle is to add water to the atmosphere through the process of transportation(which in plants release water from their leaves during photosynthesis). When forests are cut down, less moisture goes into the atmosphere and rainfall declines, sometimes leading to drought
