How much water should be added to 80 grams of common salt so as to obtain 20% salt solution​

Chemistry
1 answer:
NISA [10]3 years ago
3 0
Concentration of solution is 20%

Mass of solute( common salt) is 80g

take the amount of water as x

mass of the solvent = (80+x)

We know, concentration of solution = (mass of solute/mass of solution)×100

20=(80/80+x)×100

80+x=80×5 ( we devide the both side by 20)

x= 400-80

x=320 g

The chemical reaction in which solid calcium oxide is treated liquid water is an example of what: A) decomposition B)combustion
laiz [17]

Answer:

The chemical reaction in which solid calcium oxide is treated liquid water is an example of Synthesis reaction. Hence, the answer is (D) Synthesis.

Explanation:

The formula of Calcium Oxide is CaO.

The formula of liquid water is H₂O.

Calcium Oxide reacts with water and forms Calcium Hydroxide. The Chemical equation is shown below.

CaO + H₂O --> Ca(OH)₂.

This is a Synthesis reaction because Ca(OH)₂ is synthesized by using Calcium Oxide and water.

The product of this reaction is calcium hydroxide, also known as slaked lime.

Thus, when calcium oxide reacts with water, slaked lime is produced.  

Calcium oxide is also known as lime and is most commonly used for many purposes. It can be used for pH correction of water or for its disinfection (with excess lime).

What happens when HCl gas is passed through a saturated PbCl2 solution?
VikaD [51]
When HCl is added to a saturated solution of PbCl2, the solubility of PbCl2 would decrease so precipitation would occur. The decrease in the solubility is due to the common ion effect or the presence of Cl- ions in both compounds.

During what meterological (weather) changes does sublimation occur on earth?
insens350 [35]
Sublimation occurs more readily when definite weather circumstances are present such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes where the air pressure is less than at lower altitudes and energy such as strong sunlight is also needed. Sublimation happens a lot in the south face of Mt. Everest which have low temperatures, strong winds, intense sunlight, very low air pressure and the recipe for sublimation to occur.
