Answer:
A paper battery can work even if it is folded, cut or rolled up. A Paper battery consists mainly of carbon and paper; it can be used to power pacemakers within the body. A paper battery can be used both as a capacitor and battery. It is an ultra-thin storage device.Oct 10, 2014

Answer:
See figure 1 and 2
Explanation:
In this case, we can start with the general reaction. Acetanilide with bromine in acetic acid we will produce <u>p-bromo-acetanilide</u> (See figure 1).
In the reaction mechanism, we have as first step the attack of the double bond in the benzene ring to one of the Br atoms in bromine () and a positive carbon will be produced in benzene. This positive charge can be moved inside of the benzne ring producing the r<u>esonance structures A, B and D</u>. Resonance structure C is produced when a double bond is generating between the "N" atom and the carbon in the benzene ring.
The final step in the mechanism is when we remove the "H" atom in structure A to produce again the double bond.
See figure 2
I hope it helps!
What problem? I can’t see anything
Answer:
C. The reaction that forms α-1, 6 linkages is catalyzed by branching enzymes.
Explanation:
α-glucan branching enzyme which can also be called the Brancher enzyme or glycogen-branching enzyme is the enzyme responsible for the side chain reaction that attaches at carbon atom 6 of a glucose unit (an α-1,6-glycosidic bond).
This branching enzyme attaches a string of seven glucose units to the carbon at the C-6 position on the glucose unit, forming the α-1,6-glycosidic bond.
The volume of 0.555M KNO3 solution would contain 12.5 g of solute iss 223 mL.
<h3>What is the relationship between mass of solute and concentration of solution?</h3>
The mass of solute in a given volume of solution is related by the formula below:
- Molarity = mass/(molar mass * volume)
Therefore, volume of solution is given by:
Volume = Mass /molarity * molar mass
Molar mass of KNO₃ = 101 g/mol
Volume = 12.5/(0.555 * 101)
Volume = 0.223 L or 223 mL
In conclusion, the volume of the solution is obtained from the molarity of solution as well as mass and molar mass of solute.
