The population that experienced the highest radioactivity from chernobyl in norway were "a small community of reindeer herders called the Saami".
Typically, the term "population" denotes the total quantity of people living in a particular area, be it a city or town, region, country, continent, or even the entire world.
The native reindeer herders of Scandinavia could be known as the Sámi. These breathtaking images capture a herd during its yearly journey through summer pastures as well as wintering areas.
Therefore, the population that experienced the highest radioactivity from chernobyl in norway were "a small community of reindeer herders called the Saami".

The answer is point C.)
Cause Ocean is a large area of salt water connected to the " ocean "
(a) at the bottom - high density organic compound dissolved in methylene chloride
(b) at the bottom - saturated aqueous sodium chloride
Explanation:
Sodium chloride is dissolved in water while the organic compounds are dissolved in methylene chloride. After mixing the two solutions two layers will form because water (polar molecule) will not mix with the methylene chloride (nonpolar molecule).
The layer with higher density will be at the bottom.
(a) saturated aqueous sodium chloride (d = 1.2 g/mL) - upper layer
high density organic compound dissolved in methylene chloride (d = 1.4 g/mL) - bottom layer
(b) saturated aqueous sodium chloride (d = 1.2 g/mL) - bottom layer
low density organic compound dissolved in methylene chloride (d = 1.1 g/mL) - upper layer

Answer:-3463 kJ and -3452kJ
Explanation:
ΔU is the change in internal energy of a system and its formula is;
ΔU = q + w
Where q represents heat transferred into or out of the system. Its value is positive when heat is transfer into the system and negative when heat is produced by the system.
W represents the work done on or by the system. Its value is positive when work is done on the system and negative when it is done by the system.
For the system in this question, we see that it produces heat which means heat is transferred out of the system, therefore the value of q is negative, it can also be seen that work is done by the system which means that w is also negative.
Therefore,
ΔU = -q-w
ΔU = -3452 kJ – 11kJ
= - 3463kJ
ΔH is the change in the enthalpy of a system and its formuls is;
ΔH = ΔU + Δ(PV)
By product rule Δ(PV) becomes ΔPV + PΔV
At constant pressure ΔP = 0. Therefore,
ΔH = -q-w + PΔV
w is equals to PΔV, So:
ΔH = -q
ΔH = -3452kJ
Answer:
There are 2 double bond units and 1 lone pair, which will try to get as far apart as possible - taking up a trigonal planar arrangement. Because the lone pair isn't counted when you describe the shape, SO2 is described as bent or V-shaped.
