Plant is complex biological organism which is composed of many organic molecules that fulfill different roles in the plant, some will give the color of the plant, some are "energy reactors" like chlorophyll which capture the photons for promoting certain chemical reactions. Now the organic solvents like acetone and ethyl alcohol do not discriminate between the compounds so the solvent will extract many different molecules from the plant. The extract will be definitely a heterogeneous one.
Using a thin lay chromatography plate you may determine the spots for each organic compound as well as their retention factor for the solvent used as eluent. After concentration the solution, under vacuum, the mixture may be loaded in a chromatography column, previously filled with silica gel as stationary phase. After the elution and collection of each fraction, that contain a different molecule, the plant extract is separated.
Answer:
O2+H2 → H2O
become→zero to−2
∵ it will be reduced and oxidation state of H
2
becomes zero to +1 it will be oxidised.
∴ reaction will be redox
Explanation:
please mark me as brainalist
If T=const
P1V1=P2V2
P1*4L=P2*1L
P2=4P1
pressure increases by factor of 4
Answer: The products usually weigh more than the reactants.
