Unknown halogen x2 was added to each of two test tubes which contained aqueous nacl and aqueous nai, respectively. when hexane was added to the test tubes, an orange color developed in the top layer of the first test tube, while purple developed in the second.

a. identify x2.
b. write a balanced equation for each reaction which occurred.

Explanation:

The compound is .

The reaction included are:

 (because  bromine is less reactive than chlorine)

But , because of hexane the solution get dilute and its color changes to orange.

Now, NaI is added and we know Br is more reactive than I.

Therefore it replace it.

Reaction:

Purple color develop due to formation of Iodine.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
