Answer: Option (C) is the correct answer.

Explanation:

According to Lewis, a base is a substance or specie which is able to donate electrons.

For example, $NH_{3}$ is a lewis base because nitrogen has a lone pair of electron.

Therefore, when ammonia is dissolved in HCl it will accept the hydrogen atom as nitrogen gave electron to the hydrogen atom. As a result, hydrogen bonds with nitrogen atom.

$NH_{3} + HCl \rightarrow NH^{+}_{4}Cl^{-}$

Thus, we can conclude that it donates electrons in solution best describes a Lewis base.

Answer:

<h2>Cool the mixture to -200 degree Celsius. both gases turn their state to liquids. they are then separated using fractional distillation where as the temperature is increased, nitrogen is first collected because it has the lowest boiling point</h2>

Mark the lime poor conducter of heat and electricity.

Hence it's non metal

Yes why no ,Xenon is already has its secured place in modern periodic table.

It belongs to group 18,the Helium family and inert gas group having atomic no Z=54

The reaction below is at equilibrium. What would happen if more carbon were

schepotkina [342]

Explanation:

$C_{(s)} + O_{2(g)} \rightleftharpoons CO_{2(g)}$

According to le ch-atelier's principle when a chemical reaction at equilibrium subjected to any stress, then the equilibrium shifts in that direction in which effect of stress is reduced.

When we would add more number of carbon in above reaction then rate of forward reaction will increase to attain the equilibrium again.

Papessa [141]

If two metals both have the same color, have similar densities, and are about the same size, but one is shiny and the other is dull, they can be separated based on the lustrous physical property of a metal. Lustrous is the property of the metal to shine/gleam gently because of its particle arrangement of atoms.
