Phosphorus pentachloride reacts with water to give phosphoric acid and hydrogen chloride according to the following equation:
pcl5 + 4h20 → h3po4 + 5hci
in one experiment, 0.287 mol of pcl5 was slowly added to 3.84 mol of water.
how many grams of hcl were formed in the reaction?

52.4 grams

Explanation:

The two reactants PCl5 and H2O, must occur in a 1:4 ratio, so that tells us, that we need 4 times more H₂O than phosphorus pentachloride.

0.287 moles PCl5 multiplied by 4 equal 1.15 moles H2O. That tell sus that 1.15 moles H2O is needed.

Because we have 3.84 moles H2O, the PCL5 is the limiting reactant.

0.287 mol PCl₅ x (5 mol HCl divided by 1 mol  of PCl₅) x ( 36.5g HCl divided by moles of HCl) = 52.4 g of HCl is formed

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.
