Assignment:
In the lab you add excess hydrochloric acid to 2.65g of Na2CO3. The balanced reaction is 2HCL (aq) + Na2CO3 (aq) ---> CO2 (g) + H20 (l) + 2NaCl (aq)
1) Identify the type of reaction
2) How many grams of gas molecules can be formed from this much Na2CO3? Show the calculation of the molar masses of all necessary substances before showing the calculation of theoretical yield.
3) Use the conversion factor (22.4L gas)/(1 mole gas) to find out how many liters of gas can be produced.
4) In the lab experiment you carefully collect all of the gas formed and find that there is 425.6mL of gas. What is your percent yield?
Provide complete and step by step solution for the question and show calculations and use formulas.
