2H2 + O2 -> 2H20
What is the mass of water that is produced from 4.00 moles of oxygen gas reacting with hydrogen
gas?

                    144.08 g of H₂O

Explanation:

                     The balance chemical equation for the synthesis of water is as follow;

                                           2 H₂ + O₂ → 2 H₂O

Step 1: Find out moles of H₂O produced as;

According to balance chemical equation,

                    1 mole of O₂ produced  =  2 moles of H₂O

So,

                 4 moles of O₂ will produce  =  X moles of H₂O

Solving for X,

                    X =  4 mol × 2 mol / 1 mol

                    X  =  8 moles of H₂O

Step 2: Calculate Mass of H₂O as;

                 Mass  =  Moles × M.Mass

                 Mass  =  8 mol × 18.01 g/mol

                 Mass  = 144.08 g of H₂O

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.
