What is the result of crystals boiling the impure product with too much solvent and then cooling on ice?

Chemistry
1 answer:
VMariaS [17]3 years ago
8 0

Answer: Option (c) is the correct answer.

Explanation:

It is known that when we tend to dilute an impure product with too much of solvent then it will lead to dissolution of the solute. As a result, the chances of formation of crystal reduces.

And, when we increase the temperature then there will occur increase in the number of collisions between the solute and solvent molecules.

Hence, solubility of the solute also increases with increase in temperature,  placing it on ice bath will further reduce the crystal formation, hence no crystal should be formed in the reaction.

Thus, we can conclude that the result of crystals boiling the impure product with too much solvent and then cooling on ice is that no crystals are produced.

How do the properties of a compound like h2o or nacl illustrate the concept of emergent properties?
Softa [21]

Answer and explanation;

Na - metal

Cl - poisonous gas

NaCl - cyrstaline solid that is edible

An emergent property is a property which a collection or complex system has, but which the individual members do not.  

Water emergent properties: cohesion & adhesion, versatile solvent, temperature moderation, freezing.

The properties of a compound can be very different from the properties of the elements that make them, for example, Sodium is an explosive metal, and  Chlorine is a toxic gas, however, sodium chloride is a Delicious table salt!

2. A 2.5 mol SAMPLE OF OXYGEN GAS (O2) INCREASES TO 3.2 mol
lana [24]

696.32 mmHg is the final pressure of the gas.

<h3>What is an ideal gas equation?</h3>

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.

Given data:

P_1 = 720 mmHg              

P_2 = ?

n_1 = 2.5 mol                

n_2 = 3.2 mol

V_1 = 34 L            

V_2 = 45 L

Formula

Combined gas law

\frac{P_1 V_1}{n_1}  = \frac{P_2 V_2}{n_2}

P_2 = 696.32 mmHg

Hence, 696.32 mmHg is the final pressure of the gas.

How many atoms are in 1.50 g of Al?
Helga [31]
Question:
How many atoms are in
1.50g ofAI

Number of Mole:
Generally, the ratio within the total mass of a chemical substance and the molar mass of that chemical substance is utilized to calculate the total number of moles of the substance. The mathematical expression of the number of the mole is shown below,
n=m/M
Here, n is the total number of moles, m is the total mass and M is the total molar mass.

Answer and Explanation:


Given data

The mass of the aluminum is
m =1.50g
Note- The molar mass of the aluminum is
M=26.98g/mol
Since n=m/M
n= 1.50/26.98
n=0.0556
So the answer is A
