The tip of the blue triangles points to the direction in which the cold front is moving. Also, note that the blue color represents a cold front (as opposed to a red color that represents warm front).

The boundary between the two air masses exhibits cooling moisture that forms clouds and thunderstorms.
Answer:
The metal which is liquid in room temperature is mercury
Answer: 52.8 g of 
Explanation:
To calculate the moles, we use the equation:
a) moles of octane
b) moles of oxygen
According to stoichiometry :
2 moles of 
require 25 moles of 
Thus 0.150 moles of require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 2 moles of give = 16 moles of
Thus 0.150 moles of give =
of
Mass of 
Thus 52.8 g of will be produced from the given masses of both reactants.
Answer:
Non-polar solvents cannot dissolve polar compounds since no opposite charges exist and the polar compound is not attracted.
