1 Yellow media without gas pocket-sugar utilization with production of acid only. 2  Red media (no change in media) -no change and no sugar utilization. 3  Pink media especially at the top, ignore gas-no sugar utilization with degradation of protein resulting in alkaline end products (this may be difficult to see).
With organic solvents with long alkane chain, such as n-hexadecane and n-decane, the water droplets become much larger and the microemulsion is unstable. In this case, solvent polarity may have become a determining factor and the long alkane chain was too hydrophobic to form a stable microemulsion with water.
This is because ethene has double carbon bonds whereas ethane consists of only single carbon bond. The pi bonds are unsaturated hence the compounds consisting of pi bonds are â¦ more ready to react in order to break these pi bonds to form new bond in order to achieve higher stability.14 people found this useful.hey are this way because they only need to lose one electron â¦ to gain a stable octet which is very favorable energetically. The most reactive group of non-metals is the halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine. These are the exact opposite.
