A dependible common measurement
Answer:
Explanation:
1st) one are homogenous because the have the same kind of force 9 London force ) all the hydrocarbons are nonpolar and have a London force between their molecules
so pentane dissolve in hexane (like dissolves like )
2nd ) CBr4 has a tetrahedral shape its a nonpolar compound (London bond )
but the water is polar molecules has a ( hydrogen bond ) its molecular shape (bent shape) . Both do not dissolve in each other because they have a different kinds of bond so they are <u>not a homogenous solution </u>.
3rd) its a homogenous because the water can dissolve the ionic bonds between the Li ( cation ) and (NO3 -1 anion ).
4th ) here we can say alcohol can dissolve in a little amount why ?
- pentane has a London force bond
- Alcohol has two different parts first part has OH making hydrogen bond which cant dissolve in the pentane different kinds of bonds ,and the other part -CH3 has a London force bond that can dissolves easily in the pentane
- so one part dissolves but the other part can't dissolve so the two compound are slightly dissolves in each other that which mean its <u>not a homogenous solution </u>
Answer:
the state or quality of a material or membrane that causes it to allow liquids or gases to pass through it.
Answer:
The answer to your question is 41.6 g of AgCl
Explanation:
Data
mass of NH₄Cl = 15.5 g
mass of AgNO₃ = excess
mass of AgCl = 35.5 g
theoretical yield = ?
Process
1.- Write the balanced chemical reaction.
NH₄Cl + AgNO₃ ⇒ AgCl + NH₄NO₃
2.- Calculate the molar mass of NH₄Cl and AgCl
NH₄Cl = 14 + 4 + 35.5 = 53.5 g
AgCl = 108 + 35.5 = 143.5 g
3.- Calculate the theoretical yield
53.5 g of NH₄Cl -------------------- 143.5 g of AgCl
15.5 g of NH₄Cl ------------------- x
x = (15.5 x 143.5) / 53.5
x = 2224.25 / 53.5
x = 41.6 g of AgCl
