in the chemical equation HCI+CaCO3 which element cannot be apart of the products a carbon b chlorine c nitrogen d oxygen

Nitrogen

Explanation:

The element nitrogen cannot be a product in the given reaction.

  The reaction is;

    HCl  + CaCO₃

According to the law of conservation of matter, "matter is neither created nor destroyed in the cause of a chemical reaction".

The law suggests that, in a chemical reaction, we end up with the same species we started with. Although due to rearrangement of bonds,  new compounds can form;

Starting atoms

     H

     Cl

     Ca

      O

These species will also be found in the product.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
