Calculate the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL.
Considering the definition of dilution, the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL is 0.93 mL.
What is diluionFirst of all, you have to know that when it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeMolarity of the solution in this caseIn this case, you know:
Ci= 4 M Vi= 7 mLCf= ?Vf= 30 mLReplacing in the definition of dilution:
4 M× 7 mL= Cf× 30 mL
Solving:
(4 M× 7 mL)÷ 30 mL= Cf
Cf= 0.93 mL
In summary, the molarity of a solution prepared by diluting 7.0 mL of 4.0 M solution to a volume of 30 mL is 0.93 mL.

O 125L
ОЗК
O 302
O 87 L
The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.
How to calculate volume?The volume of a given gas can be calculated using the following Charle's law equation:
V1/T1 = V2/T2
Where;
T1 = initial temperatureT2 = final temperatureV1 = initial volumeV2 = final volumeV1 = 9LV2 = ?T1 = 325KT2 = 450K9/325 = V2/450
325V2 = 4050
V2 = 4050/325
V2 = 12.46L
Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

Increasing ions in solution will decrease the pH of a solution, while increasing the. ions in solution will increase the pH of a solution. Fill the Blank
Help me!
Answer:
Increasing the H+/H3O+ will decrease the pH, while increasing the OH- ions will increase the pH
Explanation:
so pH=-log(H), which means that the smaller H gets to 0, the more the pH rises. The larger the H+ gets, the smaller the pH
if H is 1, then pH is 0
if H is 0.1, then pH is 1
if H is 0.01, then pH is 2
and so on
if H is 0.00000000000001, then the pH is 14
When OH goes up, H goes down, so
if OH is 0.00000000000001, then the ph is 0
if OH is 0.0000000000001, then the pH is 1
and so on
If the OH is 1, then the pH is 14

Answer:
2C6H6 + 15O2 = 12CO2 + 6H2O
Explanation:
This is a combustion reaction meaning a substance (in this case Benzene or C6H6) reacts with oxygen gas (O2) and releases energy in the form of light and heat.
so Benzene (C6H6) and Dioxygen (O2) are reactants meaning they are on the left side of the equation
Carbon Dioxide (CO2) and Water (H2O) are the products meaning they are on the right side of the equation
To balance an equation you need an equal amount of each element/compound/polyatomic on each side of the equation
so 2C6H6 + 15O2 = 12CO2 + 6H2O:
(2•6) = 12 C = (12•C) = 12 C ~ 12C = 12C
(2•6) = 12 H = (2•6) = 12 H ~ 12H = 12H
(15•2) = 30 O2 = [(12•2) • (6•1)] = 30 O2
~ 30 O2 = 30 O2
so the equation is now balanced
