The balance chemical reaction is:

<span>6 Li(s) + N2(g) → 2 Li3N(s)

We use the amount of the Lithium reactant and the relations of the substances from the reaction to calculate the amount of product produced. We do as follows:

1.75 mol Li ( 2 mol Li3N / 6 mol Li ) (34.83 g / mol) = 20.32 g Li</span>

DENIUS [597]

Answer:

Explanation:

Often times, the property of air masses is a function of where they originate from especially with respect to latitude.

An air mass is certain amount of air with some unique set of temperature and vapor component.

  • Air masses differs from places to places based on where  they originate.
  • Continental air masses are usually dry and cold because there is little to no water on a land mass.
  • Air masses that originates from the surface of the ocean are predominantly moist.
  • In polar regions, the air mass is cold.
  • Around the tropics, they are usually warm due to insolation here.
