Answer:there is visible blue black coloration
Explanation:starch is a polysaccharide,it is composed of only glucose combined by glycosidic bonds.starch is majorly an insoluble carbonhydrate.
Starch consist of two distinguishable polysaccharide fraction namely amylose and amylopectin.
The iodine test is used to check for the presence of starch.
It gives a blue black coloration for amylose which is present in potato.
But in amylopectin,it gives a reddish coloration.
I honestly don’t know the answer to this one
Answer:
λ = 4.2x10^-13 m
Explanation:
c = λν
c is speed of light 3x10^8 m/s
λ is wavelength
ν is frequency
3.10^8 = λ . 7.13 × 10^20
λ = 4.2x10^-13 m
If you add a potassium nitrate and saturated solution you will make a super-saturated solution of potassium nitrate. But what to expect with this process of adding these 2. It is that the result of this solution made/forms bigger crystals that have pointed ends. If there is no appearance of the crystal it shows that the solution is not yet cooled.
Answer: The molarity of the malonic acid solution is 0.08335 M
Explanation:
To calculate the molarity of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus the molarity of the malonic acid solution is 0.08335 M
