To understand how elementary steps make up a mechanism, that the rate law for an elementary step (unlike the rate law for an overall reaction) can be determined without experiment, and how to write the rate law for an elementary step (just by analyzing its balanced equation). Very often, a reaction does not tell us the whole story. For instance, the reaction does not involve a collision between an NO₂ molecule and a CO molecule. Based on experimental data at moderate tempertures, this reaction is thought to occur in the following two steps:

What is the strongest intermolecular force between an nacl unit and an h2o molecule together in a solution? covalent bonding dipole-dipole force hydrogen bonding ion-dipole force

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

Based on its chemical properties, identify the position of each chemical family on the periodic table.
