Radiation fog forms during the night as the earth's surface cools and the air immediately above it cools in turn by conduction. If the air is moist enough, the cooling causes it to reach saturation and visible water droplets form. We often call this type of fog ground fog because it lies so close to the surface.
Reduction
half reaction
2H_2O
+ CrO_4^2- + 3e -> CrO_2^- + 4OH^-
Oxidation
half reaction
2OH^-
+ SO_3^2- -> SO_4^2- + H_2O + 2e
Balanced
overall equation
H_2O
+ 2CrO_4^2- + 3SO_3^2- -> 3SO_3^2- + 2CrO_2^- + 2OH^-

The burning of fossil fuels like coal, natural gas etc... leads to the emmission of carbondioxide which is a green house gas and leads to the increase of heat in the atmosphere. This results in greenhouse effect.
Answer:
Ethanoic or acetic acid.
Explanation:
Hello!
In this case, since the chemical formula of the compound excludes the hydrogen from the CHO form, we can infer it is a leaving group, which is likely to be bonded with an oxygen due to the high polarity of the O-H bond. In such a way, the most feasible condensed structure is:
Whereas the COOH stands for the carboxyl group; therefore the compound is ethanoic acid or acetic acid.
Regards!
Answer:
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. ... You have to exert a force AND move something to qualify as doing work.
