Common salt besides being used in kitchen can also be used as the raw material for making washing soda and baking soda.
The overall balanced reaction for washing soda preparation:
2NaCl + CaCO3 → Na2CO3 + CaCl2
NaCl is sodium chloride or common salt
Na2CO3 is sodium carbonate or washing soda
CaCO3 is calcium carbonate or limestone
The overall balanced reaction for baking soda preparation:
NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl
Baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or appears as a fine powder.
NH3 is ammonia
CO2 is carbon (II) oxide

1. The forces make the train float because the poles are the same on each side causing them to repell (north and north repell)
2. B is more stable. If you pushed A it would fall and that would cause more disturbance
