1. Based on the Law of Conservation of Mass, if 100g of sodium metal reacts with 25g of
chlorine gas, what will be the total mass of the
product, sodium chloride, created in the
chemical reaction?
2 Na Cl2
2NaCl
100gm + 25gm
+
?

30litre of li2o is 1.0002mole approximately 1 mole

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer

Answer is to avoid experimental error
