Answer:
The retention factor, k is 2.49
Explanation:
According to the theory of High-Performance Liquid Chromatography (HPLC), the retention factor (or capacity), k, of a column is the ratio of the retention time of a retained analyte (toluene) to that of the un-retained solute (methane).
This implies that:
k = =
retention factor, k = 2.49.
Note that there is no unit for retention factor, as it is a ratio.
Answer is: carbon atoms can be arranged s<span>traight chain, branched chain and ring.
</span>Hydrocarbon<span> is an </span>organic compound<span> consisting of </span>hydrogen<span> and </span><span>carbon.
</span><span>In s</span>traight chain<span> carbon atoms are bonded with only two other carbon atoms in elongate chain.
</span>In branched chain at least one carbon is bonded with more than two other carbon atoms.
Ring chain hydrocarbons are <span>cyclic </span><span>hydrocarbons</span>.
i) 2KClO3 → 2KCL + 3O2
ii) HNO3 + NaHCO3 → H20 + CO2
iii) 2Na + 2H2O → 2NaOH + H2
