Use the equation below to answer the following question: Fe+Cl2-->FeCl2   A student wants to prove the concept of limiting reactants to his labmates during class. If the student adds 56 g of Fe to 71 g of Cl2, what will the likely result of the reaction be in regards to limiting/excess reactants?

In the unbalanced chemical equation shown above for the combustion of ethanol, what least common multiple whole number coefficient should go in front of the hydrocarbon (C2H5OH) to balance the equation?    See image below

Aspirin can be synthesized in the lab by combining salicylic acid (C,H,0,) and acetic anhydride (C,H,0,) to form aspirin ( C,H,O,) and acetic acid (C,H,O,). The balanced equation for this reaction is C,H,O, + C,H,O, → C,H,0, + C,H,O, A student started with 3.33 mL acetic anhydride (density = 1.08 g/mL) and 2.61 g salicylic acid. The student synthesized 2.53 g of aspirin. Select the limiting reactant. salicylic acid (C, H,0,) acetic anhydride (C,H,O;) aspirin (C,H,O,) O acetic acid (C,H,O,) Calculate the theoretical yield of aspirin (C,H,O,). theoretical yield: Calculate the percent yield for aspirin (C,H,O).

Identify the reactants and products in a chemical equation, and complete the tables to indicate how many atoms of each type of element are present on either side of the following equations. 2KCO (s) --> 2KCl (s) + O2 (g)

3. Dry ice is the name for solid carbon dioxide. Instead of melting, solid carbon dioxide sublimes according to the equation: When dry ice is added to warm water, heat from the water causes the dry ice to sublime more quickly. The evaporating carbon dioxide produces a dense fog often used to create special effects. In simple dry ice fog machines, dry ice is added to warm water in a Styrofoam cooler. The dry ice produces fog until it evaporates away, or until the water gets too cold to sublime the dry ice quickly enough. A small Styrofoam cooler holds 15.0 Lof water heated to 85 °C. Use standard enthalpies of formation to calculate the mass of dry ice that should be added to the water so that the dry ice completely sublimes away when the water reaches 25 °C. Assume no heat loss to the surroundings. (The AH°; for CO219) is -427.4 kl/mol.)
