GC chromatograms often already have a library of compounds to determine what the substance is. In case the compound cannot be found in the library, one common alternative scientists use when performing is spiking.
Spiking involves gradually increasing the concentration of one specific compound, and looking for a rise in peak height. Here, you can identify which peak corresponds to the compound you spiked. You can do this for each alkene, to determine its peak and retention time.
Answer:
Nitrifying bacterium such as nitrosomonas or nitrobacter, whe applied to the soil, convert free ammonia or nitrogen to nitrates through oxidation. They are a group of aerobic bacteria playing an important role in the nitrogen cycle as producers of energy from inorganic source.
The schematic diagram attached summaries the action of such bacteria.
Answer:
Emulsion
Explanation:
Emulsion is a special type of mixture formed by combining two liquids that do not normally mix. An example of emulsion is;
Oil and Water
Answer:
3. water
Explanation:
Specific Heat: Specific heat of a substance is the energy required to increase temperature of 1 gram of substance by 1°C
Here water has the highest specific heat in the list,so it emit largest amount of heat with lose of small amount of temperature.
So,water can warmed body until its temperature becomes below the body temperature.
