Answer:
Examples of substances insoluble in water: oil, acetone, ether
Explanation:
Such examples of substances are non-polar and do not dissolve in water (polar compound). The classic example is oil floating in water (this happens because oil has a lower density than water).
Answer: Contamination
Explanation: This is a known contrainst when performing transformation in the lab. Normally the Pglo plasmid asides glowing under UV, possess a Amp gene that codes for resistance to the antibiotics Ampicillin. Transform cells will survive while untransformed cells will normally die. If untransformed (non glowing, non Ampicillin resistant) cells thrive in the medium, it is definitely a case of contamination. Start again but this time, disinfect appropriately bad be cautious of any potential contamination.
The chemical contractor has to retrieve the chemical and a identification analysis would have to be conducted
Answer:
pH = 1.3
Explanation:
pH is used to measure the concentration of hydrogen ions in a solution. It can be calculated as follows:
pH = -log [H+]
Since the given solution is an acid, therefore, the concentration of H+ ions is the same as the molarity/concentration of the solution.
[H+] = 0.05 m
Substitute in the above equation to get the pH as follows:
pH = -log [H+] = -log [0.05] = 1.3
Hope this helps :)
