Based on the balanced equation
C2H4 + 3O2 → 2CO2 + 2H2O
calculate the number of excess reagent units remaining when 41 C2H4 molecules and 102 O2 molecules react?
If 30.0mL of 0.500M KOH are needed to neutralize 10.0mL of HCl of unknown concentration, what's the molarity of HCl?
How much PV work is done, if 90 grams of ethylene and 120 grams of HCl are allowed to react at atmospheric pressure and the volume change is -71.2 liters?
what is the molarity of HCl in a solution prepaired by dissolving 18.25 gm HCl in 200 gm ethanol, if the density of solution is 0.86 gm per mm
Calculate the percent yield for the reaction: P4 (s) + 6 Cl2 (g) → 4 PCl3 (l) if 75.0 g of phosphorus reacts with excess chlorine gas to produce 111.0 g of phosphorus trichloride.
A 0.500 L solution of 7.50 M hydrochloric acid is used to neutralize a 250.0 g sample of calcium hydroxide. Calcium chloride - a chemical used to control highway dust, strengthen concrete mixes, and add flavor to foods - is produced by the reactio..
Chemists often use molarity ,M in Moles/liter , to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure
