B since Oxygen is more electronegative, meaning they have a strong stronger pull on the electrons creating poles
Freezing point is defined as the temperature needed for a liquid to turn into a solid and a melting point is the temperature needed for a solid to become a liquid. Sodium Chloride has a lower freezing point than water, as such when it is added to icy roads it helps to melt the ice faster by lowering the melting point of the water making it turn into a liquid faster/easier even if it is "cold" outside.
Answer:
The whole soil, from the surface to its lowest depths, develops naturally as a result of these five factors. The five factors are: 1) parent material, 2) relief or topography, 3) organisms (including humans), 4) climate, and 5) time.

Answer:-
5
Explanation:-
Chemical formula for calcium oxide = CaO
Chemical formula of water = H2O
Chemical Formula of Calcium Hydroxide = Ca(OH)2
Mass of Ca(OH)2 = 370g
Molar mass of Ca(OH)2 = 40 x 1 + ( 16 x 1 + 1 x 1 ) x 2
= 74 g mol-1
Number of moles of Ca(OH)2 = 370 g / 74 g mol-1
= 5 moles
The balanced chemical equation for this process is
CaO + H2O --> Ca(OH)2
From the equation we see
For 1 mol of Ca(OH)2 to form, 1 mol of CaO is needed to react.
For 5 mol of Ca(OH)2 to form, 5 x 1 / 1 = 5 mol of CaO is needed to react.
