Answer:
troposphere, the stratosphere, the mesosphere and the thermosphere
Explanation:
second compound
Let molar mass of x is = X
Let molar mass of y is = Y
Moles of x in second compound = Mass / molar mass = 7 / X
Moles of y in second compound = Mass / molar mass = 4.5 / Y
For second compound
7 / X : 4.5/ Y = 1:1
Therefore
X / Y = 7/4.5
Y / X = 4.5/ 7
The mass of x in first compound = 14g
moles of x in first compound = 14/X
Mass of y in first compound = 3
moles of y in first compound = 3 / Y
14 / X : 3/ Y = 14Y / 3X = 14 X 4.5 / 3 X 7 = 3 :1
Thus molar ratio in first compound = moles of x / Moles of y = 3:2
Formula = x3y
Answer:
Molar mass of K₃PO₄ = 212.27 g/m
Explanation:
K₃PO₄ (Potassium phosphate)
This is a ionic salt compounded of phosphate and potassium
Mass of potassium = 39.10 g/m
Mass of phosphorus = 30.97 g/m
Mass of oxygen = 16 g/m
Molar mass of K₃PO₄ = 39.10 x3 + 30.97 + 16 x4 = 212.27 g/m
Hydrophilic substances will dissolve better in water than hydrophobic substances. A substance that is hydrophilic is water loving or easily dissolved in water. Molecules of these substances form ionic bonds with the water molecules. Hydrophilic substances include alcohols. Hydrophobic substances repel water and do not mix.
