Atoms return to their ground state by emitting a photon of light.
Answer:
Some of the properties of cobalt silicate include:
It occurs as a crystal with red- violet type colour.
The shape of the cobalt silicate crystal is orthorhombic.
The molecular weight of cobalt silicate is 209.95.
The melting temperature of Cobalt Silicate is 1618 degrees Celsius.
The density of Cobalt Silicate is 4.63 grams per centimetre cube.
Cobalt Silicate can serve as a semi-conductor.
Answer:
The depth of the lake is 67.164 meters.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in bubble= ?
= final pressure of gas = 0.980 atm
= initial volume of gas =
= final volume of gas = 8.00 × V
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:

pressure of the gas in bubble initially is equal to the sum of final pressure and pressure exerted by water at depth h.

Where :
density of water = 
g = acceleration due gravity = 



h = 67.164 m
The depth of the lake is 67.164 meters.
