Ag,Cu,Mg,S are the answers...............
There is both. the persons body heat transfers to the ice while the cold transfers off the ice to the persons hand. thats why when you hold and ice cube for a long enough time it melts because your body heat melts it, while at the same time your hand starts to get colder.
Explanation:
Formula to calculate specific rotation is as follows.
Specific rotation (![[\alpha]](https://tex.z-dn.net/?f=%5B%5Calpha%5D)
) = 
where, 
= observed rotation
c = concentration in g/ml
l = path length in dm
It is given that,
c = 
= 0.02 g/ml
l = 20 cm = 2 dm (as 1 dm = 10 cm)
Therefore, calculate the specific rotation as follows.
Specific rotation () =
= 
= 
Thus, we can conclude that the specific rotation of this compound is .
.5 mol of A will be left over since 1.5 mol of A will be used for every 3 mol of B due to the 2:1 ratio established by the formula.
Answer:
None of these statements are true
Explanation:
(a)
Heavier and large molecules or atoms exhibit greater dispersion force than lighter ones due to easily form temporary dipoles by large molecule.
(b)
Compounds with hydrogen bonding usually have higher boiling point than that of similar compound without hydrogen bonding,
Because boiling point of a compounds depends on force of attraction between the molecules.
(c)
Non polar compounds usually have lower boiling points than polar compounds of similar mass due to dipole dipole attractive force of polar compound.
