Bobby and Jane dissolve 26.8 g of solid potassium iodide in water, then pour the solution into an excess of concentrated lead (II) nitrateJane carefully filters the resulting yellow precipitate from the solution and dries the solid overnight . The following day, Bobby finds the mass of the precipitate (which he knows to be Pbl 2 ) be 34.8 g. What is the percent yield of Bobby and Jane's reaction ? 2KI+Pb(NO 3 ) 2 2KNO 3 +Pbl 2

mention the spill to the teacher clean the area and throw the broken pieces away

explanation:

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.

the answer is a and have a great day

a electronegativity decreases beacuse the size of nucleus is bigger.
