Add 1ml of 0.18M of HCl (aq) to 1ml of 0.2M of [Ag(NH3)2]Br (aq). Write the any equation between hcl(aq) + [ag(nh3)2]br(aq) and the overall equation. Calculate k at equilibrium.
Question: A student reacts 1ml of acetic acid with 5ml (3.91 grams) of 1-Pentanol. Calculate the percent yield. I think the limiting reagent is acetic acid.. Acetic Acid: 1.0ml ( 1.05g / 1ml ) ( 1 mol / 60.1g ) = 0.0175 mol 1-Pentanol: 5.0ml ( 0.8g / 1ml ) ( 1 mol / 88.15g ) = 0.0443 mol Sulfuric acid: 1 ml ( 1.84g / 1ml ) ( 1 mol / 98.072g ) = 0.0188 mol And for a...
