Answer:
C
Explanation:
Reduction can be seen through addition (gaining) of electrons, addition of Hydrogen or removal of Oxygen
Mn7+ is reduced to Mn4+ by the addition of 3 electrons.
VOLUMEEEE IS THE CORRECT ANSWER
Alloys are used much more than pure metals because they are generally stronger and less likely to react with air or water.
Answer:Surface currents are caused by differences in water density; deepwater currents are caused by wind.
Explanation:
Answer:
Option (B) pH > 2.34 and pH < 9.60.
Explanation:
In a zwitterionic structure, overall negative charge should be 0.
It means, for glycine, the two functional groups e.g. 
and -COOH should bear equal and opposite charges in it's zwitterionic structure.
of -COOH (in glycine) = 2.34
Therefore, at a pH > 2.34, -COOH group of glycine exists predominantly as 
.
of (in glycine) = 9.60
Therefore, at a pH < 9.60, group of glycine exists predominantly as 
.
Hence we can say that at 2.34 < pH < 9.60, glycine exists predominantly in zwitterionic form due to presence of and in equal amount.
