Suppose you have 100. 00 ml of a solution of a dye and transfer 2. 00 ml of the solution to a 100. 00ml volumetric flask. After adding water to the 100. 00 ml mark, you take 5. 00 ml of that solution and again dilute to 100. 00 ml. If you find the dye concentration in the final diluted sample is 0. 000158 m, what was the dye concentration in the original solution.

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

From the options provided for each element below, choose the properties that it may have based on its location in the periodic table fluorine (f): highly reactive nonmetal shiny a conductor

Which of the following is most likely true about water in chemical systems? a) water dissolves nonpolar ionic compounds. b) water dissociates ionic compounds. c) water dissociates covalent molecules. d) water dissolves nonpolar covalent substances.
