How many liters of H2 gas would be produced when a 100.0 mL solution of 165.8 mM HCl is reacted with excess zinc as described by the reaction below? Assume a temperature of 31.2C and a pressure of 1.199 atm. Express your answer in liters using at least three significant figures. Zn (s) + 2 HCl (aq) ⟶ ZnCl2 (aq) + H2 (g)
The first two problems are to be submitted today. 1.(25PTS) At midday on the lunar surface, a temperature of 98 95°C was recorded Calculate the average speed of Neg) in m/s and mile/hr under these conditions. The formula for the average speed can be derived from the kinetic theory of gases and it is given by SRT average_speed= (molar mass) 2. (25PTS) Data: R -0,0821 L atm/K mole) -8.314 JAK mole). Atomic mass Ne-20.18 A reaction that can be used...
The next two problems are due next week, but work on these problems today with your group. 3.(25PTS) At a water treatment facility, an 750.0L tank containing Ch() has a pressure of 62.0 atm and a temperature of 303 K. (Using ideal gas equation, determine the moles of Cl(8) present. (1) What pressure would be expected if this same amount of gas occupied the same volume at the same temperature, but the Cl obeyed the Van der Waals equation of...
1. If 2.6 moles of Mg were mixed with HCl, how many moles of H2 gas would you expect to be produced? NG 3 2. If the ambient pressure is 1.009 atm and the temperature is 298 K, what volume (in liters) would moles of H, occupy? NG| 3
Las problem optiona bonus is the one that I requore help with. Thank you Nitroglycerin, for example, uelu J o (g) 2 CHNO1) -> 6 COB) +3 NG(8) + 5H2O(g) + % If 1.90 g of nitroglycerin explodes, calculate the volume (in liters) that the product gases would occupy if their total pressure is 1.60 atm at 4.95 x10°C. Data: Atomic masses H=1.008, N=14.01, 0= 16.00, C=12.01 Hints: Compute the total number of moles of gases then use the ideal...
6. Vinegar is 5.00% (m/v) acetic acid (CH3COOH). How many milliliters of vinegar would you need to react with an excess of baking soda (NaHCO3) in order to generate 10.0 L of carbon dioxide gas at 1.05 atm and a temperature of 25.0°C? 7. Shown below is the aqueous reaction of KNOX, HCl, and SnCl2. 2 KNO2 (aq) + 6 HCl(aq) + 2 SnCl2 (aq) → 2 SnCla (aq) + N20 (g) + 3 H20 (1) + 2 KCl (aq)...
