24)
a) C gets oxidized
ZnO gets reduced.
b) MnO2 gets reduced.
H and Cl both get oxidized.
25) The rxn between acid and base to produce salt and water is called neutralisation rxn.
Eg.
a) HCl + NaOH ----> NaCl + H2O
b) H2SO4 + KOH ----> K2SO4 + H2O
26) Slope of V- I graph shows Resistance.
Also, as angle between I and graph increases, R also increases. {as tan x increases}.
Using these facts, 1st resistance is greater than equivalent resistance.
So, 2nd resistor is added in parallel....
Feel free to ask any doubts
