The temperature of the air, pavement, and the type of ice-melt compound used will affect the rate at which the ice melts. There are many different ice-melt compounds available from traditional rock salt (sodium chloride) to ice-melt pellets (calcium chloride).
Answer:
Explanation:
The elements in Group I of the periodic table are called alkali metals. They are called alkali metals because they react with water to form alkali solutions. These metals are very reactive; hence they have to be stored under oil to protect them from corrosion by air and waterwaterwater
9 is B
6 is A
i’m not sure about the rest
Explanation:
Oil molecules are non-polar, and they can't form hydrogen bonds. Dispersion forces are present in C12H26 (oil).
H20 (water) are polar, has hydrogen bonds, it also has dipole-induced dipole and London dispersion forces.
The difference between them is that adhesion refers to the clinging of unlike molecules and cohesion refers to the clinging of like molecules.
In C12H26 (oil) the adhesive forces are stronger than the cohesive forces as a result, oil molecules tend to stick to the walls of the container.
In H2O (water) the cohesive forces is greater than the adhesive forces, as a result water molecules tend to stick together.
Amount of silver nitrate taken = 269.μmol 
Volume of the solution = 300. mL
Concentration of a solution is generally expressed in terms of molarity. Molarity is defined as the moles of a substance present per liter of the solution.
We want the concentration in millimoles/L.
Converting μmol to millimol solute:
μ
= 0.269 millimol
Volume from mL to L: 
Therefore concentration of the chemist's solution =
