2 answers:
Answer:
Diamond and graphite are allotropes of carbon
Explanation:
» Diamond has tetrahedral edges associating through weaker vander waal forces of attraction, it is colorless and glittering, and it is very hard.
» Graphite has hexagonal edges associating vander waal forces, it is black in color and it is soft. Example of graphite is the black rod in a dry cell.

Answer:
1) 0.18106 M is the molarity of the resulting solution.
2) 0.823 Molar is the molarity of the solution.
Explanation:
1) Volume of stock solution =
Concentration of stock solution =
Volume of stock solution after dilution =
Concentration of stock solution after dilution =
( dilution )
0.18106 M is the molarity of the resulting solution.
2)
Molarity of the solution is the moles of compound in 1 Liter solutions.
Mass of potassium permanganate = 13.0 g
Molar mass of potassium permangante = 158 g/mol
Volume of the solution = 100.00 mL = 0.100 L ( 1 mL=0.001 L)
0.823 Molar is the molarity of the solution.
