Answer:
The electrode that removes ions from solution
Explanation:
Each electrochemical cell consists of an anode and a cathode. Oxidation occurs at the anode and reduction occurs at the cathode.
At the anode, ions move from the electrode into the solution while at the cathode ions move from the solution to the electrode.
At the cathode, metal ions accept electron(s) and become deposited on the electrode hence this electrode removes ions from solution. This is reduction.
You could put carbon or oxygen
Answer:
D.) The nuclear model describes the atom as a dense, positive nucleus surrounded by a cloud of negative electrons.
Answer:
0.0059mol
Explanation:
From the ideal gas equation
PV=nRT
P=Pressure
V=Volume
R=Ideal gas constant
T=Temperature
n=number of mole
P=745mmHg
760mmHg=1atm
745mmHg=0.98atm
volume of water displaced=volume of hydrogen produced=145ml=0.145L
R=0.082Latm/mol/K
T=22°C=273+22=293K
no of mole=PV/RT
=0.98×0.145/0.082×293
=0.1421/24.026
=0.0059mol
