Answer:
By using various chemical compounds to lift the stain while being gentle enough to keep fabric intact.
Answer: Freezing point of a solution will be
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte)
= freezing point constant =
m= molality
Weight of solvent (benzene)= 1480 g =1.48 kg
Molar mass of solute (octane) = 114.0 g/mol
Mass of solute (octane) = 220 g
Thus the freezing point of a solution will be
Answer:
C.3
13AL
2.8.3
The number of electrons from the outermost shell is the valence of the element.
The population would decrease, the more predators there are the more food needed for the species .
