Replacement I think, hope this helps ;)
Explanation:
The Answer is option B.
pH is a scale for measuring either the solution is acidic or basic or neutral. In another way we can also say that pH is the measurement of concentration of hydrogen ions.
when we see the relationship between the hydrogen ions and pH, we see they are inverse relationship means if pH is low, the solution has greater hydrogen ions. So as the pH value increases the amount of hydrogen ions decreases.
That is the reason lemon juice with pH 2 has greater number of hydrogen ions.
Answer:
Explanation:
Oxidation In chemistry is the gain in oxygen, loss of hydrogen and loss of electrons. Oxidation occur when an element with gain oxygen, loss hydrogen or loss electrons, which means the element is oxidized. Compared to reduction which is loss ofoxygen, gain of hydrogen and gain of electrons.
From the the question , Ag( silver) is undergoing oxidation.
PV=nRT
P= ? atm
V= 2 L
T= 423 K
n= 2.3 moles
R= 0.08205
(P)(2)=(2.3)(0.08205)(423)
P= (79.826445)/(2)
P= 39.9132225 atm
