Answer:
Synthesis
Explanation:
Types of reactions and how they are typically written :
Synthesis : A + B ==> AB
Decomposition : AB ==> A + B
Double Replacement : AB + CD ==> AC + BD
Single Replacement : AB + C ==> AC + B
We have the following equation :
2 Na(s) + Cl2(g) ---> 2 NaCl(s)
This equation follows the A + B ==> AB structure as the two substances are being added together in the reactants side and are then together as the product.
So the equation following synthesis
