Answer:
Latitude:
Longitude:
Explanation:
Lets begin by explaining the meaning of latitude and longitude as geogrephical coordinates:
Latitude is the angular distance between the equatorial line, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.
In this sense latitude refers to the equatorial line that divides the Earth in two hemispheres (North and South).
Longitude represents the specific east–west position of a point on the Earth's surface, being longitude the prime meridian or Greenwich meridian.
So, according to the figure, where the model of the Earth is divided by latitude lines separated by and the longitude lines separated by
; we only have to count the lines from the equator to the line where the point A is, and count the lines fromo the Prime meridian to the line where point A is located.
Hence, point A location is:
Latitude:
Longitude:
Answer : The correct option is, 13.7 mole
Solution : Given,
Moles of = 27.4 moles
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 2 moles of react with 1 moles of
So, 27.4 moles of react with
moles of
Therefore, the number of moles of oxygen required are, 13.7 moles
Answer : The molecule is a polar molecule.
Explanation :
Polar molecule : When the arrangement of the molecule is asymmetrical then the molecule is polar.
Non-polar molecule : When the arrangement of the molecule is symmetrical then the molecule is non-polar.
The given molecule is,
The electronegativities of oxygen and fluorine are different. The molecular geometry of is bent. As, Fluorine is more elctronegative than the oxygen. So, the arrows putting towards the more electronegative element i.e, fluorine. These arrows do not balance each other. Due to this, the asymmetrical arrangement of these bonds makes the molecule polar.
Hence, the given molecule is polar.
