- Sedimentation and Decantation is the process of setting of solid particles from a liquid either to produce a concentrated slurry or to clarify a liquid containing solid particles . The solid must not be mixed with liquid. For example- sand insoluble in water
- Sublimation - In this process solid phase is directly transformed into vapour form without passing through liquid phase.This method is used in the purification of those substances which have sublimation property. At first the mixture should be sublimed before dissolution in liquid.
- EX- Iodine , naphthalene, ammonium chloride etc. Here, NH4Cl is seperated by sublimation.
- Evaporation is a technique used to separate out homogeneous mixtures where there is one or more dissolved salts. The process convert the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains.
- so, now by evaporation of the liquid solvent we finally get the salt that was dissolved in it that is NaCl.

Its solubility because you are looking at how much will desolve
Hey there!:
Given the reaction:
NaBr ⇌ Na⁺ + Br⁻
↓ ↓ ↓
0.150M 0.150M 0.150M
AgBr ⇌ Ag⁺ + Br⁻
↓ ↓ ↓
x x 0.150M
Therefore:
Ksp = x * 0.150
x = ( 7.7 * 10⁻¹³ ) / 0.150
x = 5.1 * 10⁻¹²
Answer B
Hope that helps!
Answer:
1.41 g of H₂O
Solution:
The equation for given reaction is as follow,
Cu₂O + H₂ → 2 Cu + H₂O
According to equation,
127 g (2 mole) Cu is produced along with = 18 g (1 mole) of H₂O
So,
10 g Cu produced will generate = X g of H₂O
Solving for X,
X = (18 g × 10 g) ÷ 127 g
X = 1.41 g of H₂O
Proton is a positively charged particle
