A tank of oxygen holds 20.0 L of oxygen (O2) at a pressure of 15.0 atm. When the gas is released, it provides 300. L of oxygen. What is the pressure of this same gas at a volume of 300. L and constant temperature
Given that the density of solid sodium is 0.968 g/cm^3, estimate the atomic (metallic) radius of a Na atom. Assess the value obtained, indicating why the result is only an estimate and whether the actual radius should be larger or smaller than the..
My paper says that will be only one isomer out of hexabromobiphenyl, C12H4Br6 And it states also that one phenyl group is still the active substituent when it is bromized. I wonder why it is only one isomer and I will be so thankful if you can dra..
