An electron is confined to a linear region with a length of the same orderas the diameter of an atom (about 100 pm). calculate the minimum uncertainties in its position and speed.
Determine the new volume of the mixture if the constant is kept constant at 635 mmHg and all the energy released is converted to work to push the piston.
A source of energy releases 3000 calories. This changed the temperature of a mass of water from 25 C to 55 C. What is the mass of the water?
If 25.0 mL of NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O4 occupy?
Calculate the wavelength of this emitted light. B) What wavelength range would you expect this complex to absorb most strongly. Explain.
PH of Acetylsalicylic Acid, The active ingredient in aspirin is acetylsalicylic acid (HC9H7O4), a monoprotic acid with a Ka = 3.3x10-4
Include activity coefficients in your solubility-product expression. The Ksp of AgI is 8.3 x1017.
a 100.-L flask contains a mixture of methane, CH4, and argon at 25°C. The mass of argon present is 228 g and the mole fraction of methane in the mixture is 0.650. calculate the total kinetic energy of the gaseous mixture.
