Question

Can u explain the process of poly unsaturation, i am getting confused?

Answer 1

Answer 2

I do not think it is a process. Can you give examples involving polyunsaturations?

Answer 3

A student investigated the reaction of different vegetable oils with hydrogen. 100 cm3 of hydrogen
was passed through 1 g samples of vegetable oils containing a suitable catalyst.
The volume of hydrogen remaining after each reaction was recorded.
vegetable oil
volume of hydrogen
remaining / cm3
P 100
Q 87
R 63
S 0
Which vegetable oils are unsaturated?
A P only
B Q and R only
C Q, R and S only
D S only
37

Answer 5

what are:
P 100 Q 87 R 63 S 0 ?

Answer 6

the are answers like a table

Answer 7

for example p=100cm3
then q=87cm3
then r= 63cm3

Answer 8

the volume of H2 remaining actually*

Answer 9

if those are volumes of hydrogen then your answer is:
C --> Q, R and S only because unsaturated bonds are hydrogenised with catalyst, so hydrogen is spent ergo unsaturated oil

Answer 10

but they are asking which vegetable oils are unsaturated*? what does unsaturation mean

Answer 11

unsaturation means double or rarely triple bonds

hence unsaturation with hydrogen... do you understand

Answer 12

okay...In an experiment 264 g of strontium reacts with 213 g of chlorine.
What is the formula of strontium chloride?
A SrCl B SrCl2 C SrCl3 D Sr2Cl

Answer 13

i know its emphirical formula, should i like take Cl or Cl2, coz in other questions like to determine the formula contain Oxygen i used O?

Answer 14

to get ratio of element in compound you should take Cl

Answer 15

ill have to go to the store now, so if you have questions ask and i will answer them when i come back

Answer 16

okay....and what is meant by dynamic equilibrium?

Answer 17

oh, dynamic equilibrium is state where rate of reaction is equal in point of creating reactants and reverse reaction, speed of both reactions is the same, it is marked as double arrow in reaction:
