The specific gravity of bone is about 1.85, of blood is about 1.06, of water is 1.00, and of urine is 1.03 to 1.035. Which substance contains the fewest particles?

Consider this initial-rate data at a certain temperature for the reaction described by

Which element has the lowest electronegativity? calcium(ca) gallium(ga) selenium(se) bromine(br)

Suppose that some of the compound spilled out of the crucible after it was heated. would that cause the percent by mass of water in the compound determined by the experiment to be too low, too high, or unchanged? briefly explain your answer.
