Answer:
1. The compound should be dissolved at the solvent boiling point.
2. It should be better none of the compound dissolve while at room
temperature.
3. The compound must have lower boiling point (low boiling point) than
melting point in hot solvent so to avoid it melts.
4. The compound have different solubility and impurity.
Explanation:
in order a compound to have a good crystallization, these are the primary consideration that should be followed.
1. The compound should be dissolved at the solvent boiling point.
2. It should be better none of the compound dissolve while at room
temperature.
3. The compound must have lower boiling point (low boiling point) than
melting point in hot solvent so to avoid it melts.
4. The compound have different solubility and impurity.
Answer:
72 km/h
Explanation:
Speed of car = 20m/s
So, here to find the speed in km/h we will change the metre to km and seconds to hours .
=>
= 72 km/hr
to change into km divide by 1000
(1 m = 1/1000km)
and,
to change into hours divide by 60*60= 3600
help kiya kya?
Soy sauce is a homogeneous mixture.
Answer:
this is due to difference in speeds of sound and light
Explanation:
light has a speed of 3×10^8 m/s and it is seen at once because it takes negligible time due to very high speed and short distance that is why as soon as lightning occurs we can see it . since thundering sound travels with speed of sound which is about 330 to 340 m/s in air hence it takes some time as described in question as 6 seconds
:<span> </span><span>Under the assumption that a cell is made up of two concentric spheres you find the surface are of the inside sphere which will be your A.
You already have your separation and dielectric constant so just use the formula you stated towards the end of your question and you get 8.93x10^-11 Farads which is about 89pF</span>
