Answer: V2= 0.224L
Explanation:
P1=3.55atm, V2= 7.35L, T1= 290, P2= 123atm, V2=?, T2= 307K
Applying general gas equation
P1V1/T1= P2V2/T2
Substitute and Simplify
3.55×7.35/290 = 123×V2/307
V2= 0.224L
Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
Answer:
When the operation of the voltaic cell, which is formed of an aluminum and silver strip takes place, the atom of aluminum loses three of its electrons and the Al3+ formed moves within the solution. The Al3+ ion gets dissolved within the solution and the electrons lost in the process moves through the wire and get acquired by the ions of silver, which then get reduced to solid Ag resulting in the mass gain of silver strip.
