Answer:
pH = 9.2
Explanation:
pH+pOH=14
But pOH= -log[OH]= -log[1.58×10^-5]= 4.8
We can now say
4.8+pH= 14
pH= 14-4.8= 9.2
Answer:
(a) from the anode to the cathode through the external circuit
Explanation:
In an electrochemical cell, there are two half cells; the oxidation half cell and reduction half cell. Oxidation typically refers to loss of electrons and reduction refers to gain of electrons.
Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell.
The electrical circuit in an electrochemical cell confirms the flow of electron. Usually a light bulb is attached. The correct option is;
(a) from the anode to the cathode through the external circuit
Answer:
It would be Density because:
Density= mass/ volume
Density refers to the amount of matter or mass of a substance over a volume
Argon is a suitable choice for light bulbs because it is inert. Compared to a reactive gas like oxygen, the metal filimant would burn up in a reactive environment, which is why a noble gas is used.
