Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... This makes a linear triiodide ion complex with is soluble that slips into the coil of the starch causing an intense blue-black color. I got this from google for a more detailed response, and hope this helps!

Urine color is the most effective method for measuring hydration status before and after exercise
Urine color is yellow color from a pigment called urochrome or urobilin. Darker pee contains less fluid, whereas lighter urine is more diluted. Dehydration may be indicated by very black urine. Don't worry if your urine doesn't match the color scheme.
Normal urine color is a pale yellow, however light amber is also acceptable. If your pee appears dark amber, you may be dehydrated and should drink additional water to compensate. Urine naturally contains yellow pigments known as urobilin or urochrome. The darker the pee, the more concentrated it is. Dehydration is the most common cause of dark urine color

Answer: Concentration of in the equilibrium mixture is 0.31 M
Explanation:
Equilibrium concentration of = 0.729 M
The given balanced equilibrium reaction is,
Initial conc. x 0 0
At eqm. conc. (x-2y) M (y) M (3y) M
The expression for equilibrium constant for this reaction will be:
3y = 0.729 M
y = 0.243 M
Now put all the given values in this expression, we get :
concentration of in the equilibrium mixture =
Thus concentration of in the equilibrium mixture is 0.31 M
Answer:
The possible isomers of C2H2Br2 are Cis- 1,2-dibromoethene, Trans-1,2-dibromoethene and 1,1- dibromethene
Explanation:
Isomerism is the phenomenon whereby organic molecules have the same molecular formular but different structure formular or spatial arrangement.
- When it has different structure formular, then it is referred to as Structural isomerism
- When it has different spatial arrangement, then it is referred to as Stereoisomerism
Dibromoethene has 2 Stereoisomer (Cis- 1,2-dibromoethene andTrans-1,2-dibromoethene ) and 1 structural isomer (1,1- dibromethene)
The lewis structures are structures showing the outer electron used in bonding.
