Normal boiling point is 99.97 degrees C and 211.9 degrees ferinhight. And a pressure of 1atm or 101.325 kPa. Hope this helps :)
Answer:
The first law of thermodynamics doesn't actually specify that matter can neither be created nor destroyed So yes we can create matter because matter is every where buildings ,structures etc. So the answer is yes!

The option that distinguishes a nuclear reaction from a chemical reaction is D. there is a change in the nucleus.
During a nuclear reaction, two light nuclei combine in order to create a new, heavier one which is different than those two original ones and has additional particles that it didn't have originally. This is what makes the difference between these two reactions.
From the equation it is evident that 2 moles of Sodium metal produces 1 mole of hydrogen gas.
At STP 1mole of any gas occupies a volume of 22.4 liters.
Therefore, 7.80 gives---(7.80×1)/22.4 moles= 0.3482 moles
Since the mole ratio of Sodium to hydrogen is 2:1, then the number of moles of sodium that reacted is given by the following expression.
(0.3482×2)/1 moles which gives 0.6964 moles.
The atomic mass of sodium is 23 thus the mass of sodium that reacted is given by:
mass=no. of moles×RAM
0.6964×23= 16.02 grams.
I cant see the chemical reaction taking place, and what is the evidence to support it
