Answer the following questions. Percent Yield from Actual and Expected Yields A scientist decides to perform a reaction between sold chromum and hydrochloric acid The reaction will form chromium (II) chloride and hydrogen gas. He takes 350.0 grams of chromium and adds it to excess hydrochloric acid. Hydrogen gas is produced and he measures the hydrogen gas produced to have a mass of 10.00 grams. Calculate the percent yield of his reaction. 1. Write the chemical reaction equation. 2. Colculate the amount of hydrogen gas that could be produced if all 350.0grams of chromium reacted This is the expected yield. 3. Divide the actual yield by the expected yeld to get the percent yield In a particular college chemistry lab, students are actually groded by their percent yeldl One lab group is asked to heat iron in the presence of excess axygen and produce iron (III) axde. If ther intial iron sample is 50.0 groms, what is their percent yield if they produce 250 grams of iron oxde? 1. Write the chemical reaction equation 2. Calculate the amount of iron oxide that could be produced if all 50.0gram of iron reacted. This is the expected yield 3. Divide the actual yield by the expected yield to get the percent yield. 4. Do you think this lob group is gaing to get a good grode for the lob? Explain your answer. and include one possible reason for their yeeld
