Fe3P2 + K2S (Yield) FeS + K3P If you mix 4.22 grams of iron (II) phosphide with 1.6 grams of potassium sulfide, how
much of each product is made and how much of the nonlimiting reactant is used up?

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Name the intersection of plane bpq and plane cpq.
