When a solid dissolves in a liquid to form a solution, solid particles become evenly dispersed among liquid particles.
What are solutions?Solutions are formed when a solute particle dissolves in another substance known as a solvent.
Usually, solutions are formed when solids dissolve in liquids.
The solid is the solute while the liquid is the solvent.
When a solid dissolves in a liquid, solid particles become evenly dispersed among liquid particles.
Therefore, solutions are formed when solute particles dissolve in solvents.

during an experiment, the percent yield of calcium chloride from a reaction was 80.34%. theoretically, the expected amount should have been 115 grams. what was the actual yield
from this reaction?
caco, + hc - cacl + co, + h20 (5 points)
a. 090.1 grams
b. 92.4 grams
c. 109.2 grams
d. 115.3 grams
The actual yield of the experiment given the data from the question is 92.4 g (Option B)
What is percentage yield?This is the ratio of the actual yield to the theoretical yield of a given reaction multiplied by 100
Percentage yield = (Actual / Theoretical) × 100
What is actual yield?This is the amount obtained from the expriment procedures
What is theoretical yield?This is the amount obtained from simple calculations as regarding the experiment.
How to determine the actual yieldPercentage yield = 80.34%Theoretical yield = 115 gActual yield =?Actual yield = percentage yield × theoretical yield
Actual yield = 80.34% × 115
Actual yield = 0.8034 × 115
Actual yield = 92.4 g

The pressure of x ml of a gas was increased from 2 atm to 4 atm at constant temperture. what will be the new volume?
The new volume of the gas given the data from the question is 1/2X mL
Data obtained from the question
Initial volume (V₁) = X mL
Initial pressure (P₁) = 2 atm
New pressure (P₂) = 4 atm
New Volume (V₂) = ?
How to determine the new volume
The new volume of the gas can be obtained by using the Boyles’ law equation as illustrated below:
P₁V₁ = P₂V₂
2 × X = 4 × V₂
2X = 4V₂
Divide both side by 4
V₂= 2X / 4
V₂ = 1/2X mL

how can you explain that even though you continue to add pure water into a substance, even though the resultant ph might differ a little, the acidity or alkalinity of substance still remains the same to that of substance?
Addition of pure water does not change pH of a solution because pure water has neutral pH.
Why the pH does not change when pure water is added?Even though you continue to add pure water into a substance, the acidity or alkalinity of substance still remains the same to that of substance because pure water has neutral pH which can't change the acidity or alkalinity of a solution.
So we can conclude that addition of pure water does not change pH of a solution because pure water has neutral pH.
