2 Na + Cl2 → 2 NaCl How many grams of Cl2 are needed to completely react with 46.5 grams of Na?
g of Cl2

Grams of Cl₂ needed : 71.781 g

Reaction

2 Na + Cl₂ → 2 NaCl

mass of Na = 46.5 g

mol of Na(Ar=23 g/mol) :

From equation, mol ratio of Na : Cl₂ = 2 : 1, so mol Cl₂ :

Mass of Cl₂(MW=71 g/mol) :

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
