You are given 250. mL of a stock 0.100 M Alanine solution and instructed to dilute a portion of it. So, you use a pipette and transfer 5.00 mL of the original stock solution into a flask and add 95.0 mL of water. Select all of the following statements that are correct concerning this procedure. Select all that apply.
A. The concentration in the 5.00 mL portion in the pipette is 0.100 M Alanine
B. The concentration of Alanine in the final diluted solution is 0.100 mole.
C. The amount of Alanine in the diluted solution is the same as the amount of Alanine in the pipette.
D. The amount of Alanine in the original stock solution is the same as the amount in the final diluted solution.
E. The amount of Alanine in the final solution is more than in the original stock solution because you added water.
F. The concentration in the final 100 mL is less than 0.100 M Alanine

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
