Question 4 of 16 Which chemical equation models a synthesis reaction ? O A. 2Na+MgCl 2 2NaCl+Mg O B. H 2 O+CO 2 H 2 CO 3 C. HCl+LiOH LiCl+H 2 O O CO 2 C+O 2

The chemical equation which is a model of synthesis reaction is option B

B. H₂O + CO₂ ---> H₂CO₃

Explanation:

A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.

A synthesis reaction is illustrated below:

A + B > C

In the illustration above, A and B are two chemical substances which serve as the reactants in the chemical reaction. A and B combine with each other to form a product C.

Common synthesis reaction include:

1. The reaction of sodium with chlorine to produce sodium chloride: Na + Cl ---> NaCl

2. The synthesis of Nitrogen (iv) oxide from nitrogen (ii) oxide and oxygen: 2NO + O₂ ---> 2NO₂

3. The synthesis of sulfur trioxide from sulfur dioxide and oxygen: 2SO₂ + O₂ > 2SO₃

From the given chemical reactions, the model of a synthesis reaction is option B

H₂O + CO₂ ---> H₂CO₃
