Lead(II) carbonate, also called “white lead,” was formerly used as a pigment in white paints. However, because of its toxicity, lead can no longer he used in paints intended for residential homes. Lead(II) carbonate is prepared industrially by reaction of aqueous lead(II) acetate with carbon dioxide gas. The unbalanced equation is :math> Pb ( C 2 H 3 O 2 ) 2 ( a q ) + H 2 O ( l ) + CO 2 ( g ) → PbCO 3 ( s ) + HC 2 H 3 O 2 ( a q ) ppose an aqueous solution containing 1.25 g of lead(II) acetate is treated with 5.95 g of carbon dioxide. Calculate the theoretical yield of lead carbonate.

Calculate the theoretical yield of lead carbonate.
Solution Summary: The author explains how the theoretical yield of lead carbonate should be calculated. Theoretical yield is calculated by the amount of limiting agent.

Write the balanced molecular chemical equation for the reaction in aqueous solution for
mercury(I) nitrate and chromium(VI) sulfate. If no reaction occurs, simply write only NR. Be
sure to include the proper phases for all species within the reaction.

?
• Draw the major product, or products, of the reaction in the drawing area below.
• If there aren't any products, because no reaction will take place, check the box below the drawing area instead.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are
enantiomers.
