Chia dung dịch X gồm các ion: NO3-, Mg2+,3 Al +,2-SO4
thành 2 phần bằng nhau:
- Cho dung dịch BaCl2 dư vào phần 1 thu được 69,9 gam kết tủa.
- Cho dung dịch NaOH dư vào phần 2 thì lượng kết tủa lớn nhất và nhỏ nhất lần lượt
là 23,3 gam và 11,6 gam. Tính số mol của các ion trong X.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
