The following volumes of solution are combined in a test tube: 2.00 ml of 0.20 m potassium iodide 1.00 ml of 1% starch 0.50 ml of 0.20 m ammonium persulfate 0.50 ml of 0.012 m sodium thiosulfate 2.00 ml of 0.20 m potassium nitrate 2.00 ml of 0.20 m ammonium sulfate what is the concentration of iodide in the solution in the test tube?

The answer to your question is: Concentration = 0.05 M

Explanation:

Data

2ml of KI 0.2M

1 ml 1% starch

0.5 ml 0.2 M ammonium persulphate

0.5 ml 0.012 M sodium thiosulphate

2 ml 0.2 M potassium nitrate

2 ml 0.2 M ammonium nitrate

Formula  to calculate moles of KI

Molarity = moles / volume

                                         moles = Molarity x volume

                                         moles = (0.2) (0.002)

                                         moles = 0.0004

Total volume = 2 + 1 + 0.5 + 0.5 + 2 + 2 = 8 ml

Molarity = 0.0004 / 0.008

Molarity = 0.05

i have no clue hope you find the answer

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
