The concentration of calcium carbonate does not appear in the rate law because it is a solid and its concentration is constant. The molar density, which is fixed, is the concentration of the solid. In this chemical reaction, only the amount of hydrochloric acid affects the rate of reaction.
They are odourless, colourless monatomic gases with full outer shells
Answer:
The change that took place is a chemical change as a chemical reaction occurs.
Vinegar = 
Baking soda = 
Reaction:
Because the easier a metal donates an electron (Low Ionization Energy), the more readily a non-metal with high electromagnetically will accept it.
Thus they match well, - one readily donates, the other readily accepts. This is how ionic bonding occurs.
Hope this helps.
