uummmIn the chemical reaction 3H2 + N2 --> 2NH3 , how many moles of NH3 will be produced if 4 moles of nitrogen react?

8moles

Explanation:

1 mole of N2 gives 2 moles of NH3

4 moles of N2 gives>( 4*2)/1

= 8moles of NH3

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.

1. they vary with a higher number because boiling is way hotter than melting
