For this problem, identify the limiting reagent and calculate the grams of Al2O3 obtained in the reaction of 100. grams of aluminum with 70.0 grams oxygen. If 125 grams of Al2O3 is actually produced, what is the % yield. The equations are not balanced. They were balanced in Exercise B. Use those coefficients to do these calculations. Al + O2→ Al2O3 What is the limiting reagent? ___________________ How many grams Al2O3 will be produced? ___________________ If 120 grams of Al2O3...

Model 4: Using Moles of Limiting Reagent in Stoichiometry The above pictures are not realistic because they involve so very few molecules. In a "real-world" sample, you are likely to have on the order of 10 molecules. Consider the following: Suppose you have a reaction vessel initially containing 13.5 moles of sulfur dioxide and 11.2 moles of oxygen mol SO, required to react with all O2 = 11.2 mol O2 x 2 mol SO 22.4 mol SO, 1 mol O2...

In the following chemical reaction, 2 mol of A will react with 1 mol of B to produce 1 mol of A2B without anything left over: 2A+B→A2B But what if you're given 2.8 mol of A and 3.2 mol of B? The amount of product formed is limited by the reactant that runs out first, called the limiting reactant. To identify the limiting reactant, calculate the amount of product formed from each amount of reactant separately: 2.8 mol A×1 mol...

I need help with part B
Explanation:
A mole ratio is the ratio between the amounts in moles of any
two compounds involved in a chemical reaction. The mole ratio can
be determined by examining the coefficients in front of formulas in
a balanced chemical equation.
Step 1: write the balanced chemical
equation.
Sb2S3(s) + 3Fe(s)→2Sb(s) +3FeS(s)
Step 2: calculate the moles of
Sb2S3 , Fe

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...

In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...
