Answer:
- <em>You can determine through observation that a mixture is a suspension </em><u>from the fact that particles separate and a solid substance is formed at the bottom of the mixture.</u>
Explanation:
<em>Suspensions</em> are heterogenous mixtures where particles settle when times passes.
The partilces in suspensions are not dissolved (solvated by a solvent). The mixtures where the particles are dissolved are solutions. Then, solutions and supensions are different in that the former have the particles solvated and the latter not.
The particles in a solution are molecules or ions. Such solvated particles in a solution are very small; in comparison,the particles on a suspension are larger. Then, the weight of the particles in a suspension makes that they separate from the liquid and settle down.
Answer:
5.62 g of F2
Explanation:
We have to start with the chemical reaction:
<u>We have a balanced reaction</u>, so we can continue with the <u>mol calculation</u>. For this, we need to know the <u>molar mass</u> of 
(70.906 g/mol), so:
Now, with the <u>molar ratio</u> between and 
we can convert from moles of and (1:3), so:
Finally, with the <u>molar mass</u> of we can calculate the gram of (37.99 g/mol), so:
I hope it helps!
The amount of solvent increases, since the solvent is the one diluting the solution, the more you want your solution diluted, the more of solvent you'd use. :)
Answer:
a solute is a substance that is dissolved in the solvent (liquid)
a solvent is a substance that dissolves a solute (solid)
a solution is the mixture of both the solute and solvent forming uniform mixture
