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

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
