Answer:
0.682L or 682mL
Use Charles Law of V1/T1 = V2/T2
V1 = 0.6L
T1 = 293K
V2=?
T2= 333K

Answer:
There are five evidences that tell whether a chemical change has occurred. These are change of color, change of odor, change in temperature or energy, formation of gas and formation of a precipitate.
Explanation:
Chemical Change- This is a type of chemical reaction which occurs when the properties of one or more atoms change and results into a<u> newly formed substance. </u>
Let's have a further discussion of the evidences.
1. Change of Color- Color change is caused by the combination of two or more substance with different molecular structures. A popular example of this is the Statue of the Liberty, which is made of copper plates. Due to the exposure of copper to elements like water, it changed color.
2. Change of Odor- This can be best presented with rotting food. During the rotting process, the food undergoes a chemical reaction. The result is a rotten smell.
3. Change in Temperature or Energy- An example of this is the burning of wood. Its change is considered non-reversible.
4. Formation of Gas- This can be best presented with the cake batter (the one being used to make cakes or pancakes). The batter rises which means it is forming gas. This is caused by the reaction of the baking soda and the acid.
5. Formation of a Precipitate- This occurs when two soluble salts combine and their outcome is an insoluble salt (this is the precipitate).
Take note that if any of these evidences occur, then there's definitely a chemical reaction.
I believe its called mitosis. Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. Hope this helps:)
Answer :
AgBr should precipitate first.
The concentration of 
when CuBr just begins to precipitate is, 
Percent of remains is, 0.0018 %
Explanation :
for CuBr is 
for AgBr is 
As we know that these two salts would both dissociate in the same way. So, we can say that as the Ksp value of AgBr has a smaller than CuBr then AgBr should precipitate first.
Now we have to calculate the concentration of bromide ion.
The solubility equilibrium reaction will be:
The expression for solubility constant for this reaction will be,
![K_{sp}=[Cu^+][Br^-]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BCu%5E%2B%5D%5BBr%5E-%5D)
![4.2\times 10^{-8}=0.073\times [Br^-]](https://tex.z-dn.net/?f=4.2%5Ctimes%2010%5E%7B-8%7D%3D0.073%5Ctimes%20%5BBr%5E-%5D)
![[Br^-]=5.75\times 10^{-7}M](https://tex.z-dn.net/?f=%5BBr%5E-%5D%3D5.75%5Ctimes%2010%5E%7B-7%7DM)
Now we have to calculate the concentration of silver ion.
The solubility equilibrium reaction will be:
The expression for solubility constant for this reaction will be,
![K_{sp}=[Ag^+][Br^-]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BAg%5E%2B%5D%5BBr%5E-%5D)
![7.7\times 10^{-13}=[Ag^+]\times 5.75\times 10^{-7}M](https://tex.z-dn.net/?f=7.7%5Ctimes%2010%5E%7B-13%7D%3D%5BAg%5E%2B%5D%5Ctimes%205.75%5Ctimes%2010%5E%7B-7%7DM)
![[Ag^+]=1.34\times 10^{-6}M](https://tex.z-dn.net/?f=%5BAg%5E%2B%5D%3D1.34%5Ctimes%2010%5E%7B-6%7DM)
Now we have to calculate the percent of remains in solution at this point.
Percent of remains = 
Percent of remains = 0.0018 %
Helium has the smallest atomic radius® Α⇒Ω
