Because there are several kind of cells in the blood, like red blood cell and white blood cell. They flow in the blood and will not precipitate, So it is called suspension.
Answer:
For this assignment, I have picked three famous soccer players from around the world. I will go over their Birth, work ethic, and downfalls. I guess that most soccer players' downfalls are going to be their injuries.
The first soccer player I found was Ricardo Kakà. Ricardo Kakà was born to Simone dos Santos, his mother, and Bosco Izecson Pereira Leite, his father, on April 22, 1982. His work ethic mostly consists of "doing it". One of Ricardo Kakà's greatest downfalls is his injuries.
The second player I found was Cristiano Ronaldo. Cristiano Ronaldo was born to Maria Dolores dos Santos and José Dinis Aveiro. He was introduced to soccer by his dad because worked at a soccer field. Cristiano Ronaldo's work ethic consisted of something that Ricardo Kakà had as well. "Get it done". Cristiano Ronaldo's downfall was that his father drank too much.
I was not surprised to see that, but I thought it was going to be injuries as well.
The final player that I picked is Luis Suárez. Luis Suárez was born to Sandra Diaz and Rodolfo Suárez. He joined his local youth team that played soccer and he loved it. His work ethic is the same as the last soccer players. "Do it." His major downfall was that he was a bad-tempered teen and he got mad at stuff. That didn't help him when his parents divorced.
Overall all of the soccer players are different and very important. They have all gone through different situations and have gotten through them through soccer.

Answer:
2.8 mol/min is the rate of appearance of 
at that moment.
Explanation:
Rate of the reaction = R
![R=\frac{-1}{2}\frac{d[N_2O_5]}{dt}=\frac{1}{4}\frac{d[NO_2]}{dt}=\frac{1}{1}\frac{d[O_2]}{dt}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B-1%7D%7B2%7D%5Cfrac%7Bd%5BN_2O_5%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7Bd%5BNO_2%5D%7D%7Bdt%7D%3D%5Cfrac%7B1%7D%7B1%7D%5Cfrac%7Bd%5BO_2%5D%7D%7Bdt%7D)
Rate of disappearance of 
is ![=-\frac{d[N_2O_5]}{dt}= 1.40 mol/min](https://tex.z-dn.net/?f=%3D-%5Cfrac%7Bd%5BN_2O_5%5D%7D%7Bdt%7D%3D%201.40%20mol%2Fmin)
![R=\frac{-1}{2}\frac{d[NO_2]}{dt}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B-1%7D%7B2%7D%5Cfrac%7Bd%5BNO_2%5D%7D%7Bdt%7D)
Rate of appearance of is ![=\frac{1}{4}\frac{d[NO_2]}{dt}:](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7Bd%5BNO_2%5D%7D%7Bdt%7D%3A)
![R=\frac{1}{4}\frac{d[NO_2]}{dt}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B1%7D%7B4%7D%5Cfrac%7Bd%5BNO_2%5D%7D%7Bdt%7D)
![\frac{d[NO_2]}{dt}=4\times 0.70 mol/min=2.8 mol/min](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BNO_2%5D%7D%7Bdt%7D%3D4%5Ctimes%200.70%20mol%2Fmin%3D2.8%20mol%2Fmin)
2.8 mol/min is the rate of appearance of at that moment.
The physical changes are:
- condensation of water vapors
- carving wax
- slicing a banana tearing
- aluminum foil
The chemical changes are:
- bleaching hair
- silver tarnishing,
- frying an egg, and
- burning paper
<h3>What are physical and chemical changes?</h3>
Physical changes are changes which occur in a substance which may alter the physical properties of the substance but does not affect the chemical properties of the substance. Physical changes are easily reversible
In physical changes, no new substances are formed. Example of a physical change is the melting of ice or candle wax.
Chemical changes are changes which alter the chemical properties of a substance and in which new substances are formed. Example of chemical changes are; the rusting of iron, bleaching hair silver tarnishing, frying an egg, and burning paper.
Chemical changes are not easily reversible.
In conclusion, physical changes do not produce new substances while chemical changes produce new substances.

Answer: 0.43 mol
Explanation:
The molar mass of NaCl = 58.44 g/mol
Therefore, the number of moles in 25 grams would be: 25g ÷ 58.44 g/mol = 0.43 mol
