The correct answer - Dalton
Answer:
basically electrons produced by the cathode are attracted towards anode positive terminal it is also called beta rays because they consist of negative charge particles in the chamber

Calculate the concentration of the solution after the dilution.
C1 * V1 = C2 * V2
The initial solution:
C1 = 250 mL
V1 = 0.96 M
The final solution:
C2 = ?
V2 = 800 mL
250 mL * 0.96 M = C2 * 800 mL
C2 = 250 mL * 0.96 M / 800 mL
C2 = 0.30 M
Hello
The balance chemical reaction is 2Al + 6HCl -à 2AlCl3 + 3H2 Assuming excess amount of HCl because it is not given Mole Al reacted = 13.5 g ( 1 mole/ 27 g) = 0.5 mole Al
Mole H2 = 0.5 mol Al ( 3 mole H2 / 2 mole Al) = 0.75 mole H2
since at STP then 1 mole gas occupies 22.414 L volume H2 = 0.75 mole (22.414 L / mol) = 16.8105 L H2
Have a nice day
For the answer to the question above, since the process is carried out at constant pressure,
<span>work = P (V1-V2) </span>
<span>= 1.3 E5 (6-12) = -7.8 E5 N.m (in this case the work is made by the system, so it is negative if work made on the system then it should be positive)</span>
