If 20-g of O2 is mixed with 2-g of H2 and the mixture is ignited, what is the mass of water that may be produced?

11.647g of water may be produced.

Explanation:

chemistry of the reaction:

2O2 + 2H2 > 2H2O + O2

64g + 4g yields 36g of water,

20g + 2g yields 11.647058824g of water

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
