Answer:
136.36 mL
Explanation:
Here we have to use the dilution formula
From C1V1= C2V2
Where;
C1= initial concentration of the solution= 12.0 M
C2= final concentration of the solution= 2.20 M
V1 = initial volume of the solution= 25.0 ml
V2= final volume of the solution= ?????
Then recall;
C1V1=C2V2
V2 = C1V1/C2
Substituting values from the parameters given;
V2= 12.0 × 25.0 / 2.20
V2= 136.36 mL
b)1.00 mol L KOH (aq)
c)1.00 mol L NaCL (aq)
d)1.00 mol L solution of CaCL2 (aq)
At equal concentrations, which of the following solutions is the most conductive?
a) C6H12O6 (aq)
b) CH3COOH (aq)
c) HClO4 (aq)
d) CH3OH (aq)
The solution with the highest pH is KOH, because it's a strong base. The most conductive solution would be HClO4, because it's a strong acid and dissociates into ions which are responsible for conducting electricity.
The solution that has the highest pH is b) 1.00 mol L KOH (aq). In the pH scale, lower values (0-6) represent acids, and higher values (8-14) represent bases. As KOH is a strong base, it dissociates completely in water to form K+ and OH- ions, thereby increasing the pH of the solution.
On the other hand, HNO3 is a strong acid and would have a low pH. NaCL and CaCL2 are salts and make neutral solutions, resulting in a pH of around 7.
The most conductive solution at equal concentrations would be c) HClO4(aq). Ionic compounds are good conductors of electricity in a solution since they dissociate into ions. HClO4 is a strong acid and would conduct electricity better than the others. The conductivity is due to the presence of ions which carry the current.

A 1.00 M solution of KOH (aq) would have the highest pH because it is a strong base. A 1.00 M solution of HClO4 (aq) would be the most conductive as it is a strong, fully ionizing acid that produces a high number of ions.
In terms of pH, a solution of 1.00 M KOH (aq) would have the highest pH. The reason is that KOH is a strong base and it completely dissociates in water to form K+ and OH- ions, the latter of which increase the pH of the solution. HNO3, on the other hand, is a strong acid and would result in a low pH. NaCl and CaCl2 are salts and would result in neutral or slightly acidic or basic solutions, depending on the corresponding acidity or basicity of their constituent ions.
Regarding the conductivity, a 1.00 M solution of HClO4 (aq) would be the most conductive. Conductivity relies on the number of ions present in the solution that are capable of carrying current. HClO4 is a strong, fully ionizing acid producing a high number of ions in the solution. The other solutions either are weak acids like CH3COOH, which ionize only partially, or contain compounds like C6H12O6 and CH3OH that don't ionize at all.

Answer:
CCI2
Explanation:
Answer:
A chemical solution is defined as a homogeneous mixture of two or more substances. There are two components of chemical solution that include solute and solvent.
Solute is the component that get dissolved in another substance and solvent is the substance that dissolve solute.
For example: carbon dioxide in water. Where carbon-dioxide is solute and water is solvent.
The field of physics known as calorimetry determines how much heat is transferred during a chemical or physical process.
It requires precisely calculating the heat transport in a system using a calorimeter, a specialist tool. Two substances coming into contact at differing temperatures normally causes heat exchange to occur until thermal equilibrium is attained. The amount of heat transported can be determined by monitoring the temperature change and taking into account the individual heat capacity of the substances involved. Calorimetry has many uses, including figuring out how much energy is in food, researching chemical processes, and looking at the thermal characteristics of various materials. It is necessary to comprehend how energy is transformed in distinct systems.
