Question

5 Fe2+ + MnO4- + 8 H+ yields 5 Fe3+ + Mn2+ + 4 H2O

In the equation above

H+ ions are reduced

Fe2+ ions are oxidized

H+ is the oxidizing agent

MnO4- is the reducing agent

Answer 1

@chmvijay

Answer 2

in the above oxidation can you tell me the oxidation state of iron in the left and right

Answer 3

no :/

Answer 4

do u know what is oxidation and what is reduction

Answer 5

oxidation is the state changed

Answer 6

loss of electrons

Answer 7

reduction is a gain of electrons

Answer 8

now can u see carefully the + charge on Fe in left and on right and tell me

Answer 9

f3 2+ ---> f3 3+

Answer 10

reduction?

Answer 11

increase in the + charge mean it has lost electron mean it has oxidized
here it has changed from +2 to +3 right

Answer 12

yes

Answer 13

LOL did u get answer now

Answer 14

What element is oxidized in the following reaction?

HNO3 + Cu yields Cu(NO3)2 + NO2 + H2O

H

N

O

Cu

Answer 15

cu?

Answer 16

yup ur right

Answer 17

What change would not result in a shift of the equilibrium position to the left?

2 A (g) + B (s) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. 3 C (g) + Energy

increasing the pressure

adding more of gas C to the system

removing some of A from the system

cooling the system

Answer 18

what u think :)

Answer 19

removing some a?

Answer 20

thats wrong,

Answer 21

yup

Answer 22

i think its cooling the system

Answer 23

its bases onLechaliers principle

Answer 24

this reaction is exothermic or endothermic can u tell

Answer 25

Which of the following reactions is not an example of an oxidation-reduction reaction?

3Br2 + 2Ga yields 2GaBr3

H2S + Cl2 yields 2HCl + S

2PbS + 3O2 yields 2PbO + 2SO2

K2Cr2O7 + KOH yields 2 K2CrO4 + H2O

Answer 26

c?

Answer 27

or d
