In your lab group, you are investigating the properties of unknown types of matter. Your teacher gives you a "detective's kit consisting of: vinegar (an acid), pH strips, and water. She asks you to design experiments to determine the chemical properties of the
unknowns. Select ALL of the experiments you might perform to observe chemical properties.
A)
measuring the pH
B)
measuring the mass
C)
measuring the density
D)
measuring the boiling point
E)
checking for reactivity with vinegar

18. determine whether each stateme blank space given. ach statement is true (t) or false (f). place your answer in the 8. when a cell is put into an isotonic solution, individual wat put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane. d. when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell. c. when a cell is put into a hypotonic solution, there is a net movement of water molecules across the cell membrane out of the cell. d. the movement of any solvent across a semi-permeable membrane is called osmosis. e. carrier proteins have the ability to change shape and physically move molecules across the cell membrane. f. in facilitated diffusion, the concentration of the molecules to be moved across the cell membrane is higher inside the cell.
