Question

tell tha answers of 24,25 and 26

Answer 1

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....
