ASAP PLEASEE 1. Bobby and Jane dissolve 26.8 g of solid potassium iodide (Kl) in water, then pour the solution into an excess of concentrated lead (ll) nitrate. Jane 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 Pbly) to
be 34.8 g. What is the percent yield of PbI2 in Bobby and Jane's reaction?
KI=165.99g/mol
PbI2= 461.01g/mol
2KI + Pb(NO3)2 – 2KNO3 + Pbl2

the answer is c i took the test

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.
