The concentration of Sn2 in a solution is determined by titrating it with a 0.1799 M Ce4 solution. The balanced net ionic equation for the reaction is: 2Ce4 (aq) Sn2 (aq)2Ce3 (aq) Sn4 (aq) In one experiment, 17.47 mL of the 0.1799 M Ce4 solution is required to react completely with 25.00 mL of the Sn2 solution. Calculate the concentration of the Sn2 solution. 0.06286 M

Why do scientists look for patterns in the world? a. patterns can explain observations. b. patterns never change, no matter what. c. patterns are easy for scientists to detect. d. patterns are all the same, through all time.

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
