Lead ions can be precipitated from solution with nacl according to the following reaction. pb2+(aq)+2nacl(aq)→pbcl2(s)+2na+(aq ) when 135.8 g of nacl are added to a solution containing 195.7 g of pb2+, a pbcl2 precipitate forms. the precipitate is filtered and dried and found to have a mass of 255.3 g .

Will mark brainliest how many electrons can be held in the energy level n = 4?

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?

What are the coefficients that will balance the skeleton equation below? n2 + h2 → nh3
