Answer:
2000 mL
Explanation:
Given data:
Number of moles KMnO₄ = 6 mol
Molarity of solution = 3M
Volume of solution in mL = ?
Solution:
Formula:
Molarity = number of moles of solute / volume of solution in L
3 M = 6 mol / volume of solution in L
volume of solution in L = 6 mol/ 3 M
volume of solution in L = 2 L
Now we convert the L into mL:
1 L = 1000 mL
2 L × 1000 mL / 1 L
2000 mL
Answer: 3915 K (3642 °C, 6588 °F)
Answer: I think so.. (sorry if i am wrong)
Explanation: Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
Answer is: A. covalent bonds.
Insulator most likely has covalent bonds, because it must have low electrical conductivity.
1) Substances with covalent bond not conduct an electric current in liquid and solid state, because they not have free ions or electrons.
2) Substances with ionic bond conduct an electric current in liquid, but not in solid state, because in liquids ions are mobile, contrary to solids where ions are fixed.
3) Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.
