Answer:
Our discussion up to now has centered on types of bonds that involve. This kind of bonding is called ionic bonding (as you are almost certainly already aware). NaCl is a solid at room temperature, with a very high melting point (801 °C), similar highly reactive metal – sodium (Na), and a pale green gas – chlorine (Cl2).
Explanation:
I hope this is what you needed. I also hope that you have a great day.
PCl₅ reacts upon contact with water to launch hydrogen chloride and supply phosphorus oxides. the primary hydrolysis product is phosphorus oxychloride PCl₅ + H₂O ========> POCl₃ + 2HCl.
Phosphorus trichloride appears as a colorless or slightly yellow fuming liquid with a pungent and irritating odor resembling that of hydrochloric acid. Causes severe burns to skin, eyes and mucous membranes.
Divide the mass of the material through its molar mass. The molar mass of a substance is the mass in grams of 1 mole of that substance. This mass is given via the atomic weight of the chemical unit that makes up that substance in atomic mass units.
One mole is described as the amount of substance containing as many number one entities atoms, molecules, ions, electrons, radicals, and lots of others. As there are atoms in 12 grams of carbon - 12(6. 023×10²³. The mass of one mole of a substance equals to its relative molecular mass expressed in grams.

Answer: B) Wood Shavings
Reason/Explanation:
Notice what options A, C, and D have on common. Ice, salt and sugar. Those are all dissolvable. Insoluble means un-able to dissolve. It can't dissolve. Wood shavings can't dissolve in water. They will just float. Sugar, salt and ice will all dissolve. Wood shavings won't.
