Question 5 5.29 pts Which is true regarding a general chemical reaction A+B - C? It is not important to convert to moles when performing stoichiometric calculations It is not important to worry about reactant amounts when performing stoichiometric calculations If A and B both will produce equal moles of C, they are both the limiting reagent The theoretical yield is not dependent on the limiting reagent The limiting reagent is the reactant that runs out last

(100 pts] The combustion of ethylene (CzHs) occurs via the following reaction, C2H4 + 02 CO2 H20 a. 15 pts] Check whether the stoichiometric equation is balanced. Determine the stoichiometric coefficients if the equation is not balanced. If 100 Kg of ethylene and 400 Kg of oxygen are fed into a batch reactor where the combustion process takes place, determine the following: . 125 pts] The limiting reactant. c.125 pts] The percentage by which the other reactant is in excess...

The limiting reactant is the chemical substance that determines the amount of product(s) that can ultimately be formed in a reaction. During the reaction, the limiting reactant is completely consumed or used up, and therefore, causes the reaction to stop The limiting reactant can be identified through stoichiometric calculations. After comparing the results, the reactant that produces the smaller mass of product is identified as the limiting reactant. Determine the excess reactant and calculate the mass of the remaining excess...

Question 6 1 pts In the reaction of magnesium chloride with sodium phosphate, how many grams of magnesium phosphate are expected when 50.0 g MgCl2 and 75.0 g Na3PO4 are reacted? 3 MgCl2 (aq) + 2 Na3(PO4)2 + Mg:(PO4)2 (8) + 6 NaCl(aq) How should you solve this problem? Decide which reactant has more grams and use that to calculate the amount of product formed Perform separate and complete stoichiometric evaluation for each reactant. Determine which produces most product and...

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...
