Answer:
The rain shadow effect
Explanation:
A rain shadow is an area of land that was forced to become a desert because a mountain or mountain range blocked all the necessary weather for plants to grow... after the air crosses over the mountains peak and begins going down the other side, the air warms up which means there's less rainfall.
Answer:
Q = 246 kJ
Explanation:
It is given that,
Mass of water, m = 200 g
Let initial temperature, 
Final temperature of water, 
We know that the specific heat capacity of water, 
So, the heat energy needed to raise the temperature is given by :
or
Q = 246 kJ
So, the heat energy of 246 kJ is needed.
Answer:
a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Explanation:
For example, in water molecules (H2O), hydrogen is covalently bonded to the more electronegative oxygen atom. Therefore, hydrogen bonding arises in water molecules due to the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule.
60 elements! I don't exactly know every element known, so if you are asking that, please tell us, but what I do know is that there were 60 elements in the periodic table by 1860.
