Calculate the change in molar Gibbs energy, ?Gm, of liquid mercury initially at 1.00 bar pressure if a pressure of 1000. bar is applied to it. The process occurs at the constant temperature of 25 ºC, and the mercury may be assumed to be incompressible and to have a density of 13.5 g cm^-3.
a sample of gas occupies 1.40 X 10 cubed mL at 25 degrees celcius and 760 mmHg. what volume will it occupy at the same temperature and 380 mmHg? which gas law is being used.
A container of gas with an adjustable volume has an initial pressure of p. The container volume is tripled at constant temperature. What is the pressure inside the container after the volume is increased
calculate the number of grams of acetic acid per 10ml of the vinegar. Since vinegar has a density of about 1.00 gram/ml, 100 ml eighs about 100 g.
Calculate the mass of nitrogen dissolved at room temperature in an 78.0 L home aquarium. Assume a total pressure of 1.0 atm and a mole fraction for nitrogen of 0.78.
The (-) enantiomer of a compound has a specific rotation [a]= -86 degrees. A sample of this pure enantiomer, when measured in a two dm sample tube, gives an observed rotation
Why does aluminum hydroxide readily dissolve in concentrated NaOH but not in concentrated NH3? Please give a thorough explanation, not just a short answer.
A gas sample has an original volume of 680 ml when collected at 720 mm and 28°C. What will be the volume of the gas sample if the pressure increases to 820 mm and the temperature increases to 55°C?
What is the initial concentration of the Fe2+(aq) solution?
One method of estimating the temperature of the center of the sun is based on the assumption that the center consists of gases that have an average molar mass of 2.00 g/mol.
Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent based solely on each element's position on the periodic table
When you initially standarized your NaOH sollution, you diluted your HCl stock solution and added water to it. If you used 24.8 ML of 0.18 M HCl stock solution and added another 26.2 mL of water, what is the new molarity of the acid
