Answer:
Hey!I will try to help with the ones I know.
solubility is a means of comparing the extent to which different solutes can dissolve in a particular solvent at a definite temperature.
A saturated solution of a solute at a particular temperature is one which contains as much solute as it can dissolve at that temperature in the presence of undissolved solute particles....
This is what I know I hope it helps you
It is the same because it's ratio is still the same between all three, and it is the same material.
Answer: The ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
Explanation:
Law of constant proportion states that In a chemical substance the elements are always present in definite proportions by mass. This law is also known as 'Law of definite proportions '.
Mass of 1 atom of sulphur = 32 g
Mass of 1 atom of oxygen = 16 g
Mass of 2 atoms of oxygen =
In formation of , 1 atom of sulfur combines with 2 atoms of oxygen and thus the mass ratio will be 32: 32= 1:1 .
Thus the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.
Answer: The name of this Hydrate is magnesium sulphate monohydrate.
Explanation:
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
a) If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of = 87.0 g
Mass of = 13.0 g
Step 1 : convert given masses into moles
Moles of =
Moles of =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For =
For =
Hence the empirical formula is
Thus the name is magnesium sulphate monohydrate.
