Explain why the form of the equilibrium constant for a chemical transformation can be predicted from its stoichiometric coefficients whereas the rate law must be determined experimentally.
undergo an isothermal compression until the pressure of the system is four times the original pressure. The process may occur in two ways:
Consider a lake containing 39 ppb (parts per billion) of parathion, which has a log Kow = 3.8. If a sample of lake water was mixed with octanol, what is the expected concentration of parathion in the octanol?
Neon(Ne) is a noble gas with atomic number 10 this is a odorless, colorless, inert monatomic gas under standard conditions but explain some facts about Neaon.
How much heat is released when 4.50 g of methane gas is burned in a constant-pressure system? CH4 (g) + 2O2(g) -> CO2 (g) + 2H2O(l) H=-890kJ
what was the mass (g) of molecular oxygen from the air that combined with the substance to produce the dense gas? B. What is the ratio of the weight of oxygen burned to the weight of the dense gas produced?
One liter of a gas has a pressure of 150.00 kPa at 25.0°C. If the pressure increases to 600.0 kPa and the temperature to 100.0°C, what would be the new volume of the gas?
