Answer:
Compound 3 is a clear liquid with a strong pleasantly fruity smell. If cooled it freezes at about −10°C. In the solid state it does not conduct electricity. ... It dissolves slightly in water, and a solution of 2g in 100mL of water doesn't change the electrical conductivity of the water.
Complete Question
Magnesium sulfate forms a hydrate with the formula 
. What is the maximum amount of water (in grams) that can be removed from 15 ml of toluene by the addition of 200 mg of anhydrous magnesium sulfate? The molar mass of 
is 120.4 g/mol; H20 = 18 g/mol.
Answer:
The value is 
of 
Explanation:
From the question we are told that
The volume of toluene is 
The mass of anhydrous magnesium sulfate is 
The formula of the hydrate is
The molar mass of is 
From the formula given we see that
1 mole of 
wil remove 7 moles of to for the given formula
Hence
120.4 g (1 mole) will remove 7 moles (7 * 18 g = 126 g ) of to for the given formula
Therefore 1 g of x g of
So
![x = \frac{x]126 * 1}{ 120.4 }](https://tex.z-dn.net/?f=x%20%20%3D%20%20%5Cfrac%7Bx%5D126%20%2A%20%201%7D%7B%20120.4%20%7D)
=> 
From our calculation we obtained that
1 g of will remove of
Then
of will remove z g of of
So
=>
=> of
Answer:
ionic bond
Explanation:
calcium is a metal and oxygen is a nonmetal. Ionic bonds occur between a metal and a nonmetal while covalent bonds occur between two nonmetals.
Answer: an amount of space between two things or people.
Explanation: hope this helps? :)
The answer would be: <span>dependent on the number of particles
If you see the ideal gas formula you know that volume is directly related to the number of particles.
Closed container volume could influence the pressure that will change the volume but the question seems to talk about open container. If the container is not closed, then the volume of container won't have any effect.
Mass is related to the number of particles, but not directly related to volume so this option is a bit ambiguous.</span>
