Question

A chemical reaction has two elements as reactants. Which type of reaction might occur?

Answer 1

Answer: The reaction is known as synthesis reaction.

Explanation:

Synthesis reaction is defined as the chemical reaction in which substances react in their elemental state to produce a single compound.

For Example: The formation of magnesium oxide from magnesium and oxygen gas.

$2Mg(s)+O_2(g)\rightarrow 2MgO(s)$

By Stoichiometry of the reaction:

2 moles of magnesium atom reacts with oxygen gas to produce 2 moles of magnesium oxide.

Hence, the reaction is known as synthesis reaction.

Answer 2

That should be a synthesis reaction
