CO(g) + NO2(g) ------> CO2(g) + NO(g) rate= k(NO2)^2 Suggest a plausible mechanism for the reaction, given that the unstable species NO3 is an intermediate.
A piece of lithium metal was added to a flask of water on a day when the atmospheric pressure was 757.5 Torr. The lithium reacted completely with the water to produce 250.0 mL of hydrogen gas, collected over the water at 23°C, at which temperature..
During an experiment, a student adds 0.339 g of calcium metal to 100.0 mL of 2.05 M HCl. The student observes a temperature increase of 11.0 °C for the solution.
A spoonful of sodium chloride is dissolved in a liter of water. What is sodium chloride in this solution?
