the two rarest non-radioactive elements are ruthenium and rhodium, each with an abundance of 1x10^-4 g/t. What is the total mass of each of these elements in the Earth's crust (1 t = 1000kg)?
When 1.025 g of naphthalene is burned in a bomb calorimeter, the temperature rises from 24.25 to 32.33 degrees celsiuc. What is the delta E reaction?
A 2.50 liter container is filled with 175g of Argon. If the pressure is 10.0 atm, what is the temperature.part B: If the temperature is 225 K, what is the pressure
Ammonia can be made by reacting calcium cyanamide (CaCN2) with water as shown: CaCN2 + 3 H2O => CaCO3 + 2 NH3.
Considering the reaction: SO2Cl2(g) --> SO2(g) +Cl2(g) Kp=2.91 and temp = 298k. the partial pressure of SO2 is 137 torr and the partial pressure of Cl2 IS 285 torr. What is partial pressure of SO2Cl2?
In a chemical reaction (unbalanced equation), AsF3 + C2Cl6 = AsCl3 + C2Cl2F4, the theoretical yield of C2Cl2F4 was calculated to be 1.86 mol. If the percent yield in the reaction was 77.2%.
