Answer:It is a gas because its particles move in many different directions.
Among the choices, the best answer is alcohol. However, the most common groups of organic compounds in fuels are the alkanes and alkenes. Alcohol can also be used in fuel, especially bioethanol. Bioethanol is a common additive in fuels for motor vehicles, and is made from corn or sugar.
Answer:
Above 7
Explanation:
The equivalence point of any titration can be read off from the appropriate titration curve.
A titration curve is a plot of the pH of analyte against the volume of titrant added.
For a strong base and weak acid, the equivalence point lies above 7.
Explanation:
The electronic configuration of sodium with Z = 11 is : 2, 8, 1
The electronic configuration of chlorine with Z = 17 is : 2, 8, 7
The Lewis structure is drawn in such a way that the octet of each atom is complete.
Thus, sodium losses one electron to chlorine and chlorine accepts this electron to form ionic bond.
Thus, the valence electrons are shown by dots in Lewis structure. The structure is shown in image below.
