Beginning with 2.5g of manganese(ii) chloride and 6.991g of sodium acetate in 100mL of water, add 11mL of acetylacetone to get phase 2 system, next add 0.491g of potassium permanganatee to 25ml of water and them added to the previous solution. Final 6.993g of sodium acetate is added to 25mL of water and added to previous solution. The final product after heating and filtration is 2.202g. What is the percent yield of tris(acetylactonato) manganese(III)?
below, 8.34 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) 2 HBr(g) Given that Kc = 86.7, calculate the equilibrium pressure of Br2.
