Answer 1

The following reaction: H2 + I2 → 2HI, is an example of  synthesis reaction

Explanation:

Synthesis reaction:

• In simple words, synthesis reaction can be stated as two or more material merge to form a new material.

•                A+X -->AX

• A synthesis reaction is always exothermic since they deliver power in the form of heat and light.

• When the metal and nonmetals are combined they produce an ionic compound.

• A synthesis reaction is essentially the reversal of decomposition reaction.

• The example of Synthesis reaction would be

• 2 H2(g) + O2(g) -->2 H2O(g)

• 3 H2(g) + N2(g)--> 2 NH3(g)
