plz help asap Excel Spreadsheet: Part A: Use Excel to generate a spreadsheet with the following information. Column A Enter the measured masses of sodium carbonate from data page #1 в Using stoichiometry, calculate the theoretical number of moles of CO2 that can be produced from each reactant entry. C Using the ideal gas law, measured volume, and temperature, calculate the theoretical pressure of CO2(g) that can be produced from the theoretical moles of CO2(8) D Actual measured pressures of...
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) +...

Please tell me if these workings are correct? If not, could you please help me correct my mistakes. Im not sure if I need to subtract the atmospheric pressure - and if I have to, I cant understand how to calculate it with what ive been given. Show sample calculations for Trial 1 only. Simply report the results for Trial 2 1. Calculate the moles of hydrogen gas produced from the reaction. (2 marks) O. 01329 - 5,43x10-Mol 1. MM...
chem 110 experiment 12 tritation vinegar need help fast please!!! The density of vinegar is 1.01 g/mL. How would this information affect your experimental results. 2.
