Answer:
Double replacement
Explanation:
The given reaction is double replacement reaction.
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
while,
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Decomposition:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Divide by the molar mass of HCl which is 36.5g/mol grams cancels out and you are left with 1.99 mol.
I believe that the best answer among the choices provided by the question is <span>It is the difference between reactant energy and maximum energy.

Answer:
According to molecular orbital theory, chemical bond occurs as electrons are able to reduce their energy by entering the resulting molecular orbitals.
Chemical bonds are not located among atoms, they are distributed all over the molecule.
Uses test methods to solve the equation of Schrodinger.
You can never do better than nature, however strong your assumption is. Calculations of minimum energy must be done by software.
