Answer:
0.861842
Explanation:
One atm. equals 760.0 mm Hg, so there will be a multiplication or division based on the direction of the change. Example #1: Convert 0.875 atm to mmHg. Solution: multiply the atm value by 760.0 mmHg / atm.
It is not sodium. If you drop hot molten sodium into water it flashes and violently reacts with water but does not quite explode like the molten sodium chloride. It most likely is not ... If you check the PH afterexplosion, water is still neutral PH.
BUT because sodium chloride is table salt. your answer is false!
Explanation:
Internal energy is the sum of all the energies inside or within a system because molecules of the system will have kinetic, potential, rotational, vibrational etc energies.
Internal energy arises because of random or disordered movement of particles within a system.
Therefore, internal energy of a system is the sum of kinetic and potential energy of all the particles present inside the system.
The variable for internal energy is "U". Also, change in internal energy is represented by .
Answer:
380g
Explanation:
Given parameters:
Number of moles of Fluorine = 20moles
Unknown:
Mass of Fluorine = ?
Solution:
The number of moles is the unit of quantifying the amount of particles in a substance.
So;
Mass of a substance = number of moles x molar mass
Molar mass of F = 19g/mol
Now;
Mass of F = 20 x 19 = 380g
