Methane and hydrogen sulfide gases react to form carbon disulfide and hydrogen gas(es). CH4(g) + 2 H2S(g) CS2(g) + 4 H2(g) At a certain temperature and pressure 28.7 L of CH4 reacts with 57.4 L of H2S. If all the CH4 and H2S are consumed, what volume of CS2 and H2 combined, at the same temperature and pressure, will be produced? a) 10.8 L of CS2 and H2 combined will be formed. b) 86.1 L of CS2 and H2 combined will be formed. c) 40.2 L of CS2 and H2 combined will be formed. d) 144 L of CS2 and H2 combined will be formed. e) 47.8 L of CS2 and H2 combined will be formed.
unchanged, or less if the residue was washed with hot distilled, deionized water instead of cold distilled deionized water
For the reaction [NH3] + [H3O+] draw the conjugate acid and base products of each reaction. Also determine whether the acid-base equilibrium would lie on the left or the right.
While in Europe, if you drive 117km per day, how much money would you spend on gas in one week if gas costs 1.10 per liter and your car's gas mileage is 41.0km/L ?
when electrons move from the fourth energy level to the second energy level, they emit visible light. explain why the light emitted when an electron makes this move in a sodium atom is a different color than the light emitted
Order these five gases that occur in the troposphere from most abundant to least abundant: Rn, CO2, CO, N2, Ar and O2.
Consider a small lake, 0.4 mile across and 11 ft deep, that contains a total of 50 tons of dissolved oxygen. Calculate the BOD (i.e. calculate the amount of oxygen required to degrade the amount of organic waste given)
A 782 mL gas sample at STP is compressed to a volume of 131 mL, and the temperature is increased to 22 ? C. What is the new pressure of the gas in Pa? Answer in units of Pa
why does water in a wide, flat shallow dish evaporate more quickly than the same amount of water in a tall, narrow vase? c) why does a sandwich on a plate dry out faster than a sandwich in plastic wrap
Calculate the rms (average) speed of ClO2 atoms or molecules at 297 oC. Use R = 8.314 kg-m2/K-s2-mol for the value of the gas constant.
The electron transport chain complexes that have higher electron affinities steal electrons from those with lower electron affinities.
A bicycle tire is filled with air to a pressure of 95.0 psi at a temperature of 19 degrees celcius. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees celcius. The volume of the tire increases by 4.0%. What..
