total pressure = ( 705 torr + 231.525torr) = 936.525torr
In an atom there are the same number of protons as electrons to start with. The answer would be 65 aswell.
I think this is done to allow even distribution of temperature in all the regions of the calorimeter. That is to make sure that there are no hot or cold spots and also ensure that the measured temperature is the actual average temperature when the readings are taken by a thermometer.
Answer:
Silicon
Explanation:
The total of electrons: 2 + 2 + 6 + 2 + 2
In neutral state: #electrons = #protons = 14
so element with atomic number of 14 is silicon
