Reaction with air, water, and hydrogen
The corrosion of solid sodium by oxygen also is accelerated by the presence of small amounts of impurities in the sodium. In ordinary air, sodium metal reacts to form a sodium hydroxide film, which can rapidly absorb carbon dioxide from the air, forming sodium bicarbonate.
Answer: 367 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 
of particles.
Enthalpy of vaporization is the amount of heat released when 1 mole of substance is converted from liquid to gaseous state.
Given : Enthalpy of vapourization of 
= 17.4 kJ/mol
To calculate the number of moles, we use the equation:
1 mole of produces heat = 17.4 kJ
8.3 moles of produces heat = 
Given : Enthalpy of vapourization of 
= 6.0 kcal/mol = 
(1kcal=4.184kJ)
25.104 kJ heat is produced by = 1 mole of
144 kJ heat is produced by = 
of
Mass of 
Thus 367 grams of must be evoparated o remove as much heat as evaporation of 1.00 kg of
Answer:
or example, most samples of the elements hydrogen, oxygen, and nitrogen are composed of molecules that contain two atoms each (called diatomic molecules) and thus have the molecular formulas H2, O2, and N2, respectively. ... A molecule of sulfur is composed of eight sulfur atoms and is therefore written as S8.
