A calorimeter contains 29.0 of water at 14.0. When 1.80 of (a substance with a molar mass of 47.0 ) is added, it dissolves via the reaction
and the temperature of the solution increases to 27.0.Calculate the enthalpy change, , for this reaction per mole of .
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
Hydrogen and oxygen react under a specific set of conditions to produce water according to the following equation. 2 H2(g) + O2(g) -> 2 H2O(g)
Calculate the partial pressure of each gas in the container. Express the pressure values numerically in atmospheres, separated by commas.
A sample of hydrogen occupies a volume of 1.20 liters at a pressure of 425 kilapascals. If the temperature of the gas is constant, what would the new volume of the gas be at 615 kilapascals?
Use the de Broglie relationship to determine the wavelengths of the following objects: an lithium atom moving at 2.5*10^5m/sUsing Heisenberg's uncertainty principle,
