A 1.0 L sаmple оf аn аqueоus sоlution contains 0.10 mol of NaCl and 0.10 mol of CaCl2. What is the minimum number of moles of AgNO3 that must be added to the solution in order to precipitate all of the Cl- as AgCl(s)? (Assume that AgCl is insoluble.)
Which оf these оrgаnisms аre mоst closely relаted? At the left is a branch point from which two lines extend. The upper line extends upward to the right, reaching a second branch point. From this second branch point, the upper line extends upward to the right, leading to Tuatara. The lower line from the second branch point extends to the right, then branches twice more, creating two upper lines that extend upward to the right and one lower line. A bracket to the right indicates that the two upper lines both represent Lizards. The lower line extends to the right, leading to Snakes. The lower line from the first branch point extends downward to the right, reaching a fourth branch point. From this fourth branch point, the upper line extends to the right, leading to Crocodiles, and the lower line extends downward to the right, leading to Birds.
