Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere.
Answer:
See the image Below
Explanation:
Single C-C bonds have free rotation and thus Newman Projections are quite useful for understanding the different 3D conformations of a molecule.
For any Newman Projection you have 2 bonded carbons, one <em>in front </em>of the other, therefore you rotate the bond by rotating the groups that are bonded to the carbons. i. e. in the 2-Methylpentane <em>(viewing the C3-C4 bond)</em> the carbons chosen are the 3rd and the 4th then you look to which are the other groups bonded; <em>2 H and an isopropyl for the 3rd one, and 2 H and a Methyl for the 4th one</em>.
The different rotations of those groups receive different names:
- <em>Anti Conformation: </em>Main groups of the two Carbons are 180º apart from one another. Making this the most stable conformation of the molecule. <em>(Taking into account steric effects)</em>
- <em>Gauche Conformation: </em>Principal groups are 60º apart from each other. Since are 6 spaces between groups (360º/6)=60º. It is less stable than an Anti conformation due to the same reason.
- <em>Eclipsed Conformation: </em>The less stable conformation since the main groups are confronted.
Your answer would be C because the fire gave the marshmellow a brown crust shwoing effect.
Answer:
D.
Explanation:
You try to get 8 electron on the outermost "shell" so you have no left over or "valence" electrons.
Answer:
C. NaCl
Explanation: The answer is C because the products are water and salt. Hydrochloric acid is a strong acid and NaOH ( sodium hydroxide is also a strong acid) are the reactants.
