Answer:
tantalum
i hope this helps<33 :)))))
Answer:
Explanation:
The Sebacic acid has strong hydrocarbon content which make it insoluble in water. Treating the unknown sample with a base for example NaOH will increase the solubility of the Sebacic acid because the carboxylic acid group will react with the base to form soluble ionic salt. The Sebacic acid is completely dissolved in the base
The resulting solution can be titrated with HCl until there is a color change signifying end of neutralization. The mole of NaOH present before the organic acid is noted, then after titration the mole of the HCl acid is subtracted from the initial mole of the base; this will give the carboxylates present in the solution.
Answer:
G : pent-2-ene
H : H2o
I : pent-1-ene
Explanation:
The OH would combine with H from H-O4SH
Then the O attached to the carbon would get detached taking the electrons with it, leaving carbon an positively charged.
The OH now combined with H-O4SH would take the H away from the acid forming H2O and (O4SH)-
The negative ion of (O4SH)- would then take the H from positively charged C forming the sulphuric acid back. It does not take the electrons with it*
Which is why the carbon can then form a double bond with the excess electron (2). the major product would be pent-2-ene and minor would be pent-1-ene.
This is because pent-2-ene is more stable than pent-1-ene. (Due to secondary carbon and primary carbon factor)
This is the whole backstage story though.
