Where stated, classify reactions both by the key reaction event (PPT, A/B, R/O) and by changes in composition (COM, DEC, SDP, DDP). 6. Вaclz(aq) + _ КЗРО,(аq) —> Вaз (РО4)2(s) + KCI(g) balance, then classify: When 41 g(BaCl2) and 28 g(K3PO4) reacted and made 40 g(Ba3(PO4)2), g(KCI) formed also In a reaction mixture of 0.19 g of BaCl, and 0.59 g of K3PO4: The 0.19 g of BaCl, are enough to form grams of Ba3(P04)2. The 0.59 g of K3PO4 are enough to form grams of Ba3(PO4)2. The limiting reagent in the mixture is The theoretical yield of Ba3(PO4)2 is g If 150 mg of Ba3(PO4)2 was isolated, the percent reaction yield is %

A tiny sample of an aqueous solution of two substances R and P is sketched below, as if it was under an imaginary microscope so powerful that individual molecules could be seen. (The water molecules are not shown.) 8 R and P can interconvert. That is, R can turn into P, and P can turn back into R: 113 5 R (aq)=P(aq) R P number of R molecules: number of P molecules: K= The equilibrium constant K for this equilibrium is interconversion reaches equilibrium. $3/1₁ Predict the number of R and P molecules in this sample when the .
