If the density of ethanol, C2H5OH, is 0.789 g mL-1. How many millilitres of ethanol are needed to produce 20.0 g of CO2 according to the following chemical equation?                   C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

Suppose a 500. mL flask is filled with 1.5 mol of CH, 0.40 mol of H,O and 1.1 mol of CO. This reaction becomes possible: CH, (g) +H,0(g)-Co(g) +3H,(g) Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of CO. You can leave out the M symbol for molarity. CHA H,O CO H, initial change equilibrium

If 28.6 g of Fe203 reacts with 14.9 g Al, identify the limiting reactant and calculate the theoretical yield of Al203 (molar mass of Fe203 = 159.7 g/mol; molar mass of Al203 = 101.96 g/mol). %3D %3D Fe2O3(s) + 2 Al(s) Al203(s) + 2 Fe(s) --> What is the limiting reactant? What is the theoretical yield of Al203? Express your answer with three significant figures.

In one experiment, 12.0 g of PCl5 was slowly added to 15.0 g of H2O according to the following balanced chemical equation: Pcl5(s)+4H2O(l) ---> H3PO4 (aq) + 5HCl (g) The molar masses for each compounds in the equation are as follows;  PCl5: 208.224 g/mol H2O: 18.015 g/mol H3PO4: 97.994 g/mol HCl; 36.45 g/mol What is the limiting reagent in this scenario?   Note! Make an accurate claim: The limiting reagent in this scenario is _____. Provide additional details and use subject specific language.   Cite evidence from what's given to you in the problem that supports your answer, hint: look at that equation!. Lastly! Fully connect the evidence to the claim/your answer to the question. Include subject specific language in your reasoning.   Your written response should LOOK exactly like the response attached. The other image is there to show how you would figure out the limiting reagent.
