What mass of aluminum carbonate reacted to form this amount of carbon dioxide? Find for this reaction as written. Write the balanced formula unit equation for the reaction. 0 votes. Thanks. If 13.5 g of Al (s) reacts with excess HCl, how many liters of … Calculate the pH of concentrated hydrochloric acid if this solution is 24.8 % HCl by weight and has a density of 1.16 g/mL. Now, use the stoichiometry to calculate moles of H2 produced: 1 mol HCl X (3 mol H2 / 6 mol HCl) = 0.500 moles H2(g), At STP, the volume of 1 mole of gas is 22.4 L, so 0.5 mol X 22.4 L/1 mol = 11.2 L. The mass of 0.5 mol H2 would be 1.0 gram, so the density of the gas is: density = mass/volume = 1.0 g / 11.2 L = 0.089 g/L, The density of any ideal gas at STP is 1 / (22.414 L/mol) = 0.044614 mol/L, (0.044614 mol/L) x (2.01588 g H2/mol) = 0.089936 g/L H2 at STP. Cl doesn't balance. Then we have these two equations. It is a good elec­tri­cal con­duc­tor. An unknown quantity of zinc in a sample is observed to produce 7.50 L of hydrogen gas at a temperature of 404 K and a pressure of 1.75 atm. Is this the answer because it's concentration is lower than LiNO3? Since you do not have that much HCl available, HCl is the limiting reactant. Q. QUESTION 15. Zn(s)+2HCl(aq) yeild ZnCl2(aq)+H2 When 0.124g of Zn is combined with enough HCl to make 51.5mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 21.7C to 24.7C. Join Yahoo Answers and get 100 points today. Calcium hydroxide (“slaked lime”) and sulfuric acid react to produce calcium sulfate and water according to the following balanced equation: Ca(OH)2(aq) + H2SO4(aq) ( CaSO4(s) + 2 H2O(l) a. Once the reaction has occurred as completely as possible, what amount (in moles) of the excess reactant remains?Express your answer to three significant figures. If a sample of 27.0 g of aluminum metal is added to 333 mL of 3.0 M hydrochloric acid, the volume of hydrogen gas pro- duced at standard temperature and pressure is (A) 2.80 L. (B) 5.60 L. (C) 11.2 L. (D) 22.4 L.
