To a reaction vessel, 21.5g of Li(s) and 21.3g of N2(g) are added. Given the reaction below, determine the maximum mass of Li3N that can be produced. Li(s) + N2(g) --> Li3N

Li₃N ( Lithium nitride)

The law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products.

mass of reactants there = 21.5 g if Li + 21.3 g of Nitrogen

= 42.8 g

hence the mass maximum mass of Li3N produced is 42.8 g

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
