A saturated solution of Ammonium Chloride is dissolved in 100 g of water.

Chemistry
1 answer:
faltersainse [42]3 years ago
5 0

Answer:

10 g

Explanation:

All we need is to read off the solubility curve attached to this answer. The solubility curve is a plot of solubility of a solute against temperature.

By reading off the solubility curve, we can know the mass of precipitate that crystallizes out as the solution is cooled from 50°C to 30°C.

From the solubility curve;

Mass of Ammonium Chloride  dissolved at 50°C = 50 g

Mass of Ammonium Chloride  dissolve at 30°C = 40 g

Hence;

Mass of precipitate formed = 50 g - 40 g

Mass of precipitate formed = 10 g

Co(g) effuses at a rate that is ______ times that of cl2(g) under the same conditions.
il63 [147K]

Answer is: the ratio of the effusion rate is 1.59 : 1.

1) rate of effusion of carbon monoxide gas = 1/√M(CO).  

rate of effusion of carbon monoxide gas = 1/√28.

rate of effusion of carbon monoxide gas = 0.189.  

2) rate of effusion of chlorine = 1/√M(Cl₂).  

rate of effusion of chlorine = 1/√70.9.  

rate of effusion of chlorine = 0.119.  

rate of effusion of carbon monoxide : rate of effusion of chlorine =

= 0.189 : 0.119 / ÷0.119.

rate of effusion of carbon monoxide : rate of effusion of chlorine = 1.59 : 1.

harina [27]

Answer:

Mass = 160 g

Explanation:

Given data:

Number of moles of sodium hydroxide = 4 mol

Mass of sodium hydroxide = ?

Solution:

Formula:

Mass = number of moles × molar mass of sodium hydroxide

Molar mass of sodium hydroxide = 40 g/mol

Mass = 4 mol × 40 g/mol

Mass = 160 g

Why is citric acid added to food?
kobusy [5.1K]

C is wrong, the real answer is B: to add tartness, and the reason why is because citric acid comes from jam, jellies, and more! And that is why the answer B is the correct answer.

Hope this helped!

Nate

(P.S. if you buy jams and real the ingredients, it will say "citric acid." :))
