In the lower troposphere, ozone is one of the components of photochemical smog. It is generated in air when nitrogen dioxide, formed by the oxidation of nitrogen monoxide from car exhaust, reacts by the following mechanism.(1) NO2(g) NO(g) + O(g)(2) O(g) + O2(g) O3(g)Assuming the rate of formation of atomic oxygen in step 1 equals the rate of its consumption in step 2, use the data below to calculate the following quantities.k1 = 7.0 10-3 s-1; [NO2] = 4.0 10-9 Mk2 = 1.0 106 L/mol·s; [O2] = 1.0 10-2 M(a) the concentration of atomic oxygen [O]M(b) the rate of ozone formationmol/L·s
If equal masses of N2 and H2 (7.00 grams each) are combined to produce ammonia NH3, how many grams of ammonia could be produced at maximum yield.
You have two gas tanks, one is 7.00 L and the other is 3.50L, and one of the tanks has oxygen in it and the other has acetylene. If the tank wth the oxygen has a pressure of 145 atm, what is the pressure of the other tank?
How many moles of table salt (NaCl) are in a box that has 117 grams of salt? (atomic mass of Na = 23.0; atomic mass of Cl = 35.4)
Determine the mass of carbon dioxide produced when .85 grams of butane reacts with oxygen according to the following equation : 2C4 H10 + 13O2 ->8CO2 + 10H2O
The combustion of butane produces heat according to the equation 2C4H10(g) + 13O2(g) -> 8CO2(g) + 10H2O(l) ->H°rxn = -5,314 kJ/mol What is the heat of combustion per gram of butane
