Chlorine released from chlorofluorocarbons (CFCs) reacts with ozone in the atmosphere to form oxygen. The proposed reactions are
1. Cl(g)+O3(g)=ClO(g)+O2(g)
2.ClO(g)+O2(g)=Cl(g)+O2(g)
Identify the species that acts as a catalyst and the one that acts as an intermediate in these reactions.catalyst=intermediate=
2Na + 2H2O → + H2 How many moles of hydrogen gas are produced when 0.066 mole of sodium is completely reacted?
a student is asked to calculate the amount of heat involved in changing 10 grams of liquid bromine at room temperature (22.5 C) to vapor at 59 C. To do this, one must use tables 8.1 and 8.2 for information on the specific heat, boiling points
What is the gauge pressure of the gas in this mercury manometer if h = 53 mm and the atmospheric pressure is 781 mmHg? What is the absolute pressure of the gas?
When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 27.6 g of carbon were burned in the presence of 87.2 g of oxygen, 13.6 g of oxygen remained unreacted. What mass of carbon dioxide was produced?
V is the volume, and n is a number that can be 1, 2, 3, ... . Assume that A=1. Determine the work done by the piston. Propose a physical meaning to the term "n" in the above equation.
How much heat is required to warm 219 g of ice from -45.7°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C
At what temperature would a 1.20 M NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? K_f for water is 1.86 C/m
Calculate the number of moles of cytochrome c3+ (Fe3+) formed from cytochrome c2+ (Fe2+) with the Gibbs energy derived from the oxidation of 1 mole of glucose
The initial pH of chloroacetic acid is 1.90, (which I found from using the quadratic equation to find x in a RICE table because I was given the initial concentration of 0.124M and told to find the pH of a 10.0 mL solution.)
hydroxylamine nitrate contains 29.17 mass % N, 4.20 mass % H, and 66.63 mass O. If its molar mass is between 94 and 98 g/mol, what is its molecular formula?
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.
Calculate the total mass of acetic acid dissolved in the solution contained in the volumetric flask (f) The mass(g) of acetic acid dissolved in the solution contained in the volumetric flask came drom the 25.00 ml vinegar sample.
