hichkok12 [17]

Answer:
Arachidonic Acid and PGE₁ are both carboxylic acids with Twenty Carbon atoms. The differences are that Arachidonic acid contains Four cis Double Bonds and no other functional groups, whereas PGE₁ has One Trans Double Bond, Two Hydroxyl and One Ketone Functional Groups.. In addition, a part of the PGE₁ chain forms a Five Membered Ring.

What is the ph of a solution with [h3o+] = 1 × 10-9 m?

FrozenT [24]

PH scale is used to determine how acidic, basic or neutral a solution is
pH can be calculated using the H₃O⁺
ph can be calculated as follows
pH = - log[ H₃O⁺]
[H₃O⁺] = 1 x 10⁻⁹
pH = - log [1 x 10⁻⁹]
pH = 9
pH of solution is 9

Develop a demonstration to show how weight is not the same thing as mass

maksim [4K]

Answer with Explanation:

"Mass" and "weight" should never be used interchangeably with each other. Mass refers to the total amount of matter that can be measured in an object, while weight refers to the measure of the force of gravity that is acting on the object's mass.

The mass of an object is constant (meaning, it doesn't change even if the object will be placed on another location) while the weight of an object relies on the force of gravity. So, this means that your mass on Earth and on the moon are identical, however, your weight on Earth and on the Moon are different. You will weigh lesser on the Moon because it has a lesser surface gravity than that of Earth.

So, this explains the answer.
