Answer:

B) Ni(s)

Explanation:

The question inquires which of the substances listed in the options is composed of the metallic bond. This means that we have to carefully consider the options and identify which of them is a metal. Clearly, only Ni(s) is a metal.

Metallic bonds result from the electrostatic attraction between metal cations and delocalized electrons. The nature of metallic bonding accounts for many of the physical properties of metals, such as conductivity and malleability(Khan Academy).

How many grams of sodium hyrdioxde are in 251.0ml f 0.600m
Furkat [3]

Answer:

There are 6.024 grams of sodium hydroxide in the solution.

Explanation:

Molarity=\frac{Moles}{Volume (L)}

Moles (n)=Molarity(M)\times Volume (L)

Moles of sodium hydroxide = n

Volume of sodium hydroxide solution = 251.0 mL = 0.251 L

Molarity of the sodium hydroxide = 0.600 M

n=0.600 M\times 0.251 L=0.1506 mol

Mass of 0.1506 moles of NaOH :

40 g/mol\times 0.1506 mol = 6.024 g

There are 6.024 grams of sodium hydroxide in the solution.

What would happen to a glass of water placed in a closet for a few days? Why do you think this would happen?
Deffense [45]

Answer: It would evaporate. Random higher energy molecules in the surface and in the air will add energy by collision to the water molecules leading some of them to escape the liquid which is evaporation.
