Which change will create a more dilute solution?

Chemistry
2 answers:
dedylja [7]3 years ago

I think the correct answer would be the third option. The change that will create a more dilute solution should affect the amount of the solvent since it is the component that is greater than the solute. Being dilute would mean there is a very small amount present of a solute in a solution. Increasing the amount of the sovent, would result to a lesser concentration of the solute.

Answer:

increasing the amount of solvent

Explanation:

Solvent is the species which is present in larger amount as compared to solute in a solution

Dilution is reverse of increasing concentration

When we use term concentration we consider the amount of solute present in a solution.

1) When we add more solute to a solution, we increase the concentration of the solution with respect to solute.

2) When we decrease the amount of solvent in the solution we are increasing the concentration of the solute (the amount of solute per unit amount of solvent increases). So by evaporating the solvent we are decreasing the amount of solvent and thus increasing the concentration of solution.

3) when we increase the amount of solvent we are decreasing the concentration of solute per unit of solvent. It means we are diluting the solution.

4) increasing the volume of the solution means no change in concentration. As it means we are adding more of solution of the same concentration to the solution of previous concentration.

The density of cadmium is 8.65 g/mL, what is the volume of a 33.4 g object made of pure cadmium?
Rzqust [24]

Answer:

Volume = 3.86 ml (Approx)

Explanation:

Given:

Density of cadmium = 8.65 g/ml

Mass of pure object = 33.4 g

Find:

Volume pure cadmium

Computation:

Volume = Mass / Density

Volume = 33.4 / 8.65

Volume = 3.86 ml (Approx)

How much heat is released when 24.8 g of ch4 is burned in excess oxygen gas?
balu736 [363]

The given question is incomplete. The complete question is:

How much heat is produced when 24.8 g of CH_4 is burned in excess oxygen gas

Given: CH _4
+2O_2\rightarrow CO_2+2H_2O  ΔH= −802 kJ.

Answer: 1243.1 kJ

Explanation:

Heat of combustion is the amount of heat released on complete combustion of 1 mole of substance.

Given :

Amount of heat released on combustion of  1 mole of methane = 802 kJ kJ/mol

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

1 mole of CH_4 weighs = 16 g  

Thus we can say:  

16 g of CH_4 on combustion releases heat = 802 kJ

Thus 24.8 g of CH_4 on combustion releases =\frac{802}{16}\times 24.8=1243.1kJ

Thus heat released when 24.8 g of methane is burned in excess oxygen gas is 1243.1 kJ
