What is the white precipitate that forms while the reaction mixture is heated? The reaction is the hydrolysis of the ester Butyl benzoate yields products 1-butanol and benzoic acid.
A gaseous mixture containing 0.220 mol fraction of carbon tetrachloride (CCl4) and 0.780 mol fraction of dry air is initially at 60.0°C and 1127 mmHg.
The density of water decreases from 1.000g/mL at 3.98°C to 0.9170g/mL as ice at 0°C. By what volume (in mL) would a 2.632 liter flexible plastic bottle increase.
When 5.00g of LiCl is added to 100g of water the temperature of the water was found to increase by 9.94*C. Calculate the molar enthalpy of solution for LiCl. Assume the specific heat of the mixture is 4.18 J/g*C.
A lithium atom is contained in a cubic well 10 nm on a side. (a) Calculate the energy (joules) required to achieve the transitions from the ground state to the first excited state for this system
Explain Net Ionic Equations and Balancing, These are only eight out of a fifty-three question hand out, but with eight answers to reference off of I think I'll be far more successful in my attempts at this.
an airplane is pressured to 650 mm Hg, which is the atmospheric pressure at a ski resort at 1.30 * 10^4 ft altitude. If air is 21% oxygen,
Ethanol v dimethylether, What are the molecular weights of ether and dimethylether? Are they isomers of each other or is each an isomer of something else?
The NO molecule has a double degenerate electronic ground state and a double degenerate excited state at 121.1 cm- 1. Calculate and plot the electronic contribution to the molar heat capacity of the molecule up to 500K
Rubidium has two naturally occuring isotopes. The relative abundance of rubidium-85 is 72.17%; its atomic mass is 86.91 amu. Determine the average atomic mass of rubidium.
