<span>It generally does not mean that there is double the oxygen, but in this case there is double, because the subscript number tells how many atoms of that element are in a particle. In this case, there are two of the oxygen, hence the DI-oxide verbiage, and one of the carbon. When there is only one, it's MONOxide, to indicate only one atom.</span>
Answer:
The correct answer is:
C. Rising steam from the cup of cocoa.
Rising steam from the cup of cocoa is the part of this scenario that convection can be best observed.
Explanation:
it would be a crystalline solid, because it could be extended in multiple directions.
Include:
- Adding cleanser makes the paperclip fall through the water to the base of the dish.
- Soap is a surfactant.
- Surfactants lessen the surface pressure of a fluid.
- The surface strain of water is the thing that upheld the paper cut.
Agar is used to assist establish an anaerobic environment that promotes nitrate reduction.
Nitrate Reduction test:
- The nitrate in the broth is converted to nitrite by organisms that can produce the nitrate reductase enzyme, which can then be further converted to nitric oxide, nitrous oxide, or nitrogen.
- Anaerobic respiration and denitrification are two processes that can convert nitrate to a variety of compounds.
- While denitrification only reduces nitrate to molecular nitrogen, anaerobic respiration employs nitrate as the bacterium's final electron acceptor, reducing it to a range of chemicals.
- The nitrate reduction test is based on the detection of nitrite and its capacity to produce a red precipitate (prontosil), which is a water-soluble azo dye, when it combines with sulfanilic acid to create a complex (nitrite-sulfanilic acid).
