Can you please help me with question 1.
Which of the following is NOT true about "yield"? * The percent yield is the ratio of the actual yield to the theoretical yield. The value of the actual yield must be given in order for the percent yield to be calculated. The actual yield may be different from the theoretical yield because insufficient limiting reagent was used. The actual yield may be different from the theoretical yield because reactions do not always go to completion.
II AM Lab data percent yield carbon dioxide.pdf Name Sect Percent Yield of Carbon Dioxide To predict the amount of carbon dioxide gas that should be produced in a Purpose: chemical reaction. Then calculate the amount of carbon dioxide actually produced and determine the percent yield. The reaction is represented in the equation below: CH,COOH + NaHCO, → NaCH,C00 + H20 + CO2 Materials: sodium bicarbonate (aka baking soda), acetic acid solution (aka vinegar), Erlenmeyer flasks, balance .Procedure: 1. Measure and record the mass of a 250-mL Erlenmeyer flask. Label it as flask A. 2. Add approximately 7.5 g of sodium bicarbonate to flask A. 3. Measure and record the mass of a second 250-ml Erlenmeyer flask. Call it flask B. 4. Add approximately 75 g of acetic acid solution to flask B. 5. Slowly add acetic acid to flask A until the reaction has stopped. Do not add all of the vinegar; just enough to complete the reaction. 6. After the reaction has stopped, measure and record the masses of…

Suppose 65.0 g of K(s) reacts with 25.0 g oxygen gas to produce 54.7 g of potassium oxide. WHat is the % yield. (In class we got 70.0%). When solving could you go over in this problem by teaching me what the actual yield, theorictical yield, and percent yield are and how to find each one of those. It really confuses me which one is which and how to solve for each of them.
