1.Sodium hydrogen carbonate, NaHCO3, can be decomposed completely by heating. 2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g) A sample of impure NaHCO3 with an initial mass of 0.739 g yielded a solid residue (consisting of Na2CO3 and other solids) with a final mass of 0.564 g. Determine the mass percent of NaHCO3 in the sample. 2.In a process for producing acetic acid, oxygen gas is bubbled into acetaldehyde, CH3CHO, containing manganese(II) acetate (catalyst) under pressure at 60°C. 2CH3CHO(l) +...
A recipe for scones asks for 1.80 g of baking soda (sodium hydrogen carbonate). Upon heating at 180 °C at a pressure of 1.00 bar, baking soda decomposes as follows: 2 NaHCO3(s) + CO2(g) + Na2CO3(s) + H20(1) If the volume of the dough before baking (i.e. before the decomposition reaction takes place) is 668 ml, what will be the total volume of the scones after baking, in mL? Assume that the rising of the dough is only caused by...
