Answer:
A. a mixture.
Step-by-step explanation:
If the perfume is made from water and anything else, it is a mixture.
B. is <em>wrong</em>, because water is a liquid at room temperature.
C. is <em>wrong</em>, because water is a compound.
D. is <em>wrong</em>, because the perfume is a mixture of water and other compounds.
If we consider the reaction CH₃O⁻ + H₂O ⇌ CH₃OH + OH⁻ in the forward direction, the base in the reaction is CH₃O⁻
A compound can be acidic, basic or neutral in nature. Basicity of the compound is determined when it either releases hydroxide ions, donates electrons or else accepts the protons from a compound.
In the reaction CH₃O⁻ + H₂O ⇌ CH₃OH + OH⁻:
CH₃O⁻ accepts proton or [H+] ion to become CH₃OH. Thus, CH₃O⁻ is the base in the reaction
H₂O donate [H+] ion or proton, therefore H2O change into OH-. Thus, H₂O is an acid in the reaction.

To get the concentration of the second solution let us use the following formulae
C1V1=C2V2 where C1 is concentration of first solution and V1 is the volume of solution first solution. on the other hand C2 is the concentration of second solution and V2 is the volume of second solution.
therefore
0.8×2=(2+10)×C2
1.6 =12×C2
1.6/12=C2
C2 = 0.1333mg/mL
The percent composition of Cesium and Fluorine in CsF are 87.493 % and 12.507 % respectively.
<h3>What is a percentage composition?</h3>
Percent composition is very simple. Percent composition tells you by mass what percent of each element is present in a compound.
Molecular mass of Cs = 132.9054519
Molecular mass of F = 18.9984032
Molecular mass of CsF = 132.9054519 + 18.9984032 = 151.9038551
CsF: Percent composition by element:
Cesium (Cs) = = 87.493 %
Fluorine (F) = = 12.507 %
Hence, the percent composition of Cesium and Fluorine in CsF are 87.493 % and 12.507 % respectively.

C. Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent
B.The temperature of the solvent is another factor that affects how fast a solute dissolves. Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
A. solute in solid state), temperature and amount of stirring.
