Consider the decomposition of 50.0g of sodium carbonate, an ingredient found in baking powder. If 19.25 grams of the gaseous product is colllected at STP, what is the percent yield?
Na2CO3-Na2O + CO2

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?
