When NO(g) reacts with H2(g) to form N2(g) and H2O(l), 376 kJ of energy are evolved for each mole of NO(g) that reacts.
Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation.Use the SMALLEST INTEGER coefficients possible and put the energy term LAST in the appropriate box
The coinage metals -- copper, silver, and gold -- crystallize in a cubic closest packed structure. Use the density of copper (8.95 g/cm3) and its molar mass (63.55 g/mol) to calculate an approximate atomic radius for copper.
If it takes 66.8 min for the concentration of a reactant to drop to 20.0% of its initial value in a first-order reaction, what is the rate constant for the reaction in the units min-1?
If 100.0 mL of NO (at STP) reacts with 400.0 mL of O2 at STP, calculate the partial pressure of NO2 in the final reaction mixture.
