Answer:

            Option-A is the correct answer

Explanation:

Lithium belong to group 1 metals. Hence, it can loose one electron to form lithium ion i.e. Li⁺¹ or Li⁺

While, Nitrogen is non-metal and hence has the ability to gain the electron lost by lithium metal. Furthermore, Nitrogen can gain maximum 3 electrons to acheive noble gas configuration. Hence, three Li atoms will loose their electrons and Nitrogen will gain those three electrons to form nitride ion i.e. N³⁻.

At 27.00 °c a gas has a volume of 6.00 L . What will the volume be at 150.0 °c
mojhsa [17]
T₁ = 27°C = 27 + 273 = 300K,  V₁ = 6 L,

T₂ = 150°C = 150 + 273 = 423K,  V₂ = ?,

By Charles' Law:      V₁/T₁= V₂/T₂

                                 6/300 = V₂/423

                                  423*(6/300) = V₂

                                  8.46 = V₂

           Volume at 150°C =8.46 L.
