The number of particles (molecules, atoms, compounds, etc.) per mole of a substances is known as Avagadro number. It is equal to 6.022×10^23 mol-1 and is expressed as NA.
Number of moles is the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×10^23 elementary entities of the substance. Since 6.022 x 10^23 is the Avagadro number, one mole is equal to Avagadro number.
One mole of a substance is the ratio of mass of the substance by the molecular mass of the substance. Thus the mass of one mole of a substance is equal to the substance's molecular weight. Thus one mole of a substance is the atomic mass unit of a substance and since one mole is equivalent to the Avagadro number,we can conclude that one Avagadro number is one atomic mass unit of the substance.
After 2 hours of research and calculations, the answer is E: Pepsi is bootleg
C
because the mass never changes, it is always equal on both sides.
Answer:
D
Explanation:
What an interesting amusing question.
The formula for KE = 1/2 m v^2.
v implies that there is motion.
The answer you are looking for is the body of water that has 0 for v.
A cloud moves, so it is not the answer.
A hailstone moves until it hits the ground. I'm assuming it's either on it's way down or it is caught in some sort of updraft in a cumulonimbus cloud. So it has motion.
Same comment for a raindrop. It has a v until it hits the ground so I'm assuming it is not the answer.
I've never seen a puddle of water move. It can only evaporate. So of all your choices, this one (D) is likely the right answer.
Answer:
C. Electron Energy Level or Cloud
Explanation:
The legend details how the nucleus, electron energy level, and alpha particle trace will look on there.
