Answer:
C
Explanation:
Iodine is used to test for starches. When iodine is placed in a solution with starch (non-reducing sugars) it turns blue-black color. When amylase, a starch, is mixed with saliva, it is ‘digested’ to glucose, a reducing sugar (the brown colour of the aqueous solution remains).
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,

Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,

Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,

If V = 2V and p = 2P
Then,


Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
