Lead is a highly poisonous metal. The mass percentage of lead in the 250 g aqueous solution was found to be 1.2 x 100%
by extracting the lead with an excess of iodide and weighing the resulting PbL. How many micrograms (ug) of lead iodide
were measured?

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
