Concept Introduction:
Balancing equations:
In a reaction, the number of molecules before and after the reaction should be equal. That means the number of moles of particular compound on either side of the reaction should be equal, this can be done by multiplication with the number of molecules required to make them equal in a reaction.

General Chemistry: Atoms First
- Butane gas, C4H10, is sold to campers as bottled fuel. Its density at 25C and 1.00 atm is 2.38 g/L. What volume of butane gas at 25C and 1.00 atm is required to heat one gallon of water (d=1.00g/mL) from 25C to 98C ? The reaction for the combustion of butane (H f =125.6kJ/mol) is C4H10(g)+132 O2(g)4CO2(g)+5H2O(g)arrow_forwardWhen two cotton plugs. one moistened with ammonia and the other with hydrochloric acid, are simultaneously inserted into opposite ends of a glass tube that is 87.0 cm long, a white 1111g of NH4Cl forms where gaseous NH3 and gaseous HC1 first come into contact. NH3(g)+HCl(g)NH4Cl(s) At approximately what distance from the ammonia moistened plug does this occur? (Hint: Calculate the rates of diffusion for both NH3 and HCI, and find out how much faster NH3 diffuses than HCI.)arrow_forwardYou heat 1.000 quart of water from 25.0C to its normal boiling point by burning a quantity of methane gas, CH4. What volume of methane at 23.0C and 745 mmHg would you require to heat this quantity of water, assuming that the methane is completely burned? The products are liquid water and gaseous carbon dioxide.arrow_forward

(a) H for a reaction (b) S for a reaction (c) G for a reaction (d) S for a substancearrow_forwardperform stoichiometric ca1cu1uions for reactions involving gases as reactants or products.arrow_forwardCarbon monoxide, CO, and oxygen, O2, react according to 2CO(g)+O2(g)2CO2(g) Assuming that the reaction takes place and goes to completion, determine what substances remain and what their partial pressures are after the valve is opened in the apparatus represented in the accompanying figure. Also assume that the temperature is fixed at 300 K.arrow_forward
- Oxygen gas can be generated by heating potassium chlorate: heat 2KCI(s) + 30,(g) 2 KCIO, (s) 2KCI(s) + What volume of oxygen gas, collected by displacement of water and measured at 780.9 torr and 80.0 °C (vapor pressure of watergo.0 °C -355.63 torr), will be formed by the decomposition of 48.8 g of potassium chlorate? Be sure your answer has the correct number of significant figures. Note: Reference the Conversion factors for non-SI units and Fundamental constants tables for additional information.arrow_forwardThe atmosphere slowly oxidizes hydrocarbons in a number of steps that eventually convert the hydrocarbon into carbon dioxide and water. The overall reaction of a number of such steps for methane gas is:CH4(g) + 5 O2(g) + 5 NO(g) ------> CO2(g) + H2O(g) + 5 NO2(g) + 2 OH(g) Suppose that an atmospheric chemist combines 155 mL of methane at STP, 885 mL of oxygen at STP, and 55.5 mL of NO at STP in a 2.0-L flask. The flask stands for several weeks at 275 K. If the reaction reaches 90.0% of completion (90.0% of the limiting reactant is consumed), what is the partial pressure of each of the reactants and products in the flask at 275 K? What is the total pressure in the flask?arrow_forwardMg(s) + 2 HCl(aq) → MgCl2(g) + H2(g) PV = nRT R = 0.082061. 2. The volume of hydrogen gas produced was not at standard temperature and pressure. Convert the volume at the pressure and temperature of the experiment to a volume at standard temperature and pressure: STP (T = 273.15K and P = 1.00 atm). Mass of flask/stopper/5 mL H2O=112.794 g Mass of flask/stopper/filled flask of H2O=250.302 g Volume of gas space in flask (the difference between the above two measurements converted to L) =0.137508 L Trial 1: mass of Mg (g) =0.013 g pressure= 1.0104 atm temperature= 298.35 K moles of H2 =0.00054 molarrow_forward
