Because physical you can cause the change. chemical happens on its own
I believe the answer is E 85 %
You should have learned the question
m(in g) = n (mole) * M(molar mass)
You need to find the mass of glucose, which the mole of the glucose is given and now you find the molar mass of the glucose which is looking up on a period table and find the average mass of each element and multiple by its number of atom in glucose
M = 12.01 g/mol *6 (for Carbon) + 16.00 g/mol * 6(for oxygen) + 1.01 g/mol *12(for hydrogen)
M = 180.18 g/mol (number may differ a little bit depends on the average mass given on the period table that you have)
Now sub the M=180.18 into the equation m=n*M
m = 1.3 mol * 180.18 g/mol
m = 234.234 g
The mass of glucose is 234.234g and the mass of the mixture is 276g
Simply take the mass of glucose and divide by the mass of the mixture, then multiply by 100
234.234g / 276g = 0.84867
0.84867 * 100 = 84.867%
84.867% ~ 85%
Hope this help!
P.S. I believe this is how you do this question, but I’m not a expert at chemistry, the answer could be wrong. I’m really sorry if it is wrong
In an ionic bond, electrons are transferred from one stone to another atom (shared).
Answer:
A
Explanation:
Limonene has a boiling point of 176C and (+)-carvone has a boiling point of 231C.
In distillation, the temperature is gradually increased until one of the components begins to vaporizes out of the solution. This vapor is then condensed into a different container. The component that vaporizes first will do so at a lower temperature than the second. Therefore, the component that has the lower boiling point will vaporize first.
PH is the negative logarithm of the hydrogen ion concentration
