When a solution of sodium lactate,
ch3ch(oh)coona, is mixed with an aqueous copper(ii)
solution, it is possible toobtain a solid salt of copper(ii)
lactate as a blue-green
hydrate,(ch3ch(oh)coo)2c xh2o.
elemental analysis of the solid tells us that the solid is 22.9%
cuand 26.0% c by mass. what is the value for x in the formulafor
the hydrate?

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
