Answer:
D
Explanation:
As bioindicators are the organism that indicate or monitor the health of the environment
Answer:
Hence,
1) removed
2) drained through the stopcock
3) get eye level with
4) slow the draining
5) switch to a new flask
Explanation:
After mixing the solutions in a separatory funnel, the stopper should be removed and the liquid should be drained through the stopcock, and the layers allowed to separate. When you get close to the interface between the layers, get eye level with the funnel and turn over to slow the draining heat up until the first layer is collected. Switch to a new flask get eye level with it to collect the second layer.
Answer:
Actually graphene is not occurred in naturally.
Explanation:
graphene is a layer or a sheet which is extracted from graphite because graphite is layered material. most of the time famous scotch tape may produce graphene but you can't identify it without using electron microscope
Answer:
See explanation
Explanation:
Whether a ligand is strong or weak highly depends on its position in the spectrochemical series. Ligands that are found towards the left hand side of the series are weak field ligands while ions that occur towards the right hand side of the series are strong field ligands. The spectrochemical series is an arrangement of ligands in order of increasing magnitude of crystal field splitting.
Most of the strong field ligands have strong pi bonds and are capable producing greater crystal field splitting.
NH3, an and NO2 are all strong field ligands hence they produce long wavelengths and lead to the formation of diamagnetic complexes.
The household substances that will turn blue litmus paper red are: A) bleach and D) Vinegar. This is because bleach contains acidic solutions; and vinegar contains a percentage of organic acids for example, acetic acid.
