in a thermonuclear device, the pressure of 0.050 litters of gas within the bomb casing reaches 4.0 x10^6 atm. when the explosion destroys the bomb casing the gas is released into the atmosphere where it reaches a pressure of 1.00 atm. what is the volume of the gas after the explosion? assume constant temperature and number of moles.
If 32 mL of 6.8 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid ?
In the reaction below, 6.31 atm each of Br2 and I2 were placed into a 1.00 L flask and allowed to react: Br2(g) + I2(g) 2 IBr(g) Given that Kc = 80.8, calculate the equilibrium pressure of IBr.
Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway enzyme that results in the inactivation of that enzyme
