What is the balanced form of the chemical equation shown below? Ny(o) + H2(o) - NH (O)
O A N (0) + Holo) - 2NH3(g)
O g
B. N2(o) + H2(g) - 2NH()
O (+
C. N2(o) + 3H2(o) - 2NH3(g)
O D. Ng(9) + H2(9) - NH (9)

c

nitrogen gas + hydrogen gas produces ammonia

N2( g)+ H2(g)=NH3( g)

hydrogen valency= 1, nitrogen =3 .Exchange them= NH3

balance

put 2 in front of NH3 to make nitrogen 2 .Them hydrogen is now 6,add3 to hydrogen to make them balance.

N2+3H2=2NH3

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.
