<h2>Answer:</h2>
Valence electrons are that electrons that are present in the atom, outside the nucleus in orbits. The list of atoms with correct number of valance electrons is as follows;
A. Nitrogen: 5
B. Silicon: 4
C. Oxygen: 6
D. Magnesium: 2
Im not certain but i believe it is the Magnitude
H2O as it has a relative atomic mass of 18
The average kinetic energy of 1 mole of a gas at -32 degrees Celsius is:
3.80 x 103 J
The relationship between volume and temperature of a gas, when pressure and moles of a gas are held constant, is: V*T = k.
FALSE
The relationship between moles and volume, when pressure and temperature of a gas are held constant, is: V/n = k. We could say then, that:
If the moles of gas are tripled, the volume must also triple.
If the temperature and volume of a gas are held constant, an increase in pressure would most likely be caused by an increase in the number of moles of gas.
TRUE
If the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil.
TRUE
35 - AB
36 - BD
33 - true
34 - False
20 - 6
21 - orthohombic
