Explanation:
Alkanes have the molecular formula of "CnH2n+2" which means for every carbon molecule there are two hydrogens plus two more. For example when there is one Carbon there are four hydrogens, this molecule is known as "Methane"
No. A voltage reading is a result of a difference in cell potential of the cells. Even if you added the volume, it would still not affect because what matters is the concentration of the ions which give the potential gradient. All you did was add the quantity in terms of volume but the substance in it is still the same.
Answer:
This is a physical test. A chemical test for starch is to add iodine solution (yellow/brown) and look for a colour change. In the presence of starch, iodine turns a blue/black colour. ... Benedict's reagent will give a positive test result for glucose but not for starch.
