The size of the transition metal atoms reduces slightly from left to right in the periodic table. Explain what factor must be considered in explaining this decrease? In particular, why does the size decrease at all as well as why is the decrease so gradual?
Calculate the mass of oxygen (in mg) dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air.
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..
