a. Hydrogen
Hydrogen has a line at 410 nm.
Mercury has a line at 405 nm.
Sodium and neon have no lines near 412 nm.
It is B, and also for a moment I didn't understand that 4.69 x 10^22. I almost did this whole problem wrong.
If you are asking for the word for this definition it is a <span>attraction by the two nucluei</span>
the melting point of water is 32 degrees Fahrenheit , 0 degrees Celsius. <span />
<h2>The required "option is b) hydrogen bonds must be broken to raise its temperature.</h2>
Explanation:
- Water has high specific heat due to hydrogen bonds present in it.
- The Ionisation of water does not affect the specific heat of the water.
- On decreasing the temperature, there is the formation of bonds hence option (d) is wrong.
- On increasing the temperature, there is the breaking of bonds hence option (b) is correct.
