Zinc reacts with iodine in a synthesis reaction. Determine the theoretical yield if a 125.0g sample of zinc was used. Determine the percent yield if 515.6 g product is recovered.
Select a phospholipid and use it to illustrate the action of phospholipase A2 and discuss the structural ramifications of this reaction on the membrane.
Acetylene (C2H2) can be produced from the reaction of calcium carbide (CaC2) with water. Draw the localized electron orbital model (hybridized orbital model) for the acetylide anion (C22-), showing and lone pair electron orbital.
The reaction of methane and water is a way to prepare hydrogen according to CH4 (g) + H2O = Co2 (g) + H2 (g) a) If 995 g of CH4 reacts with 2510 g of water, how many moles of reactants and products are there when the reaction is finished
