The element is silicon (Si). It forms minerals like quartz and rocks such as granite.
Answer:
Sodium (Na)
Explanation:
The element on the periodic table at Column (group) 1, period 3 is Sodium (Na)
The reaction is a synthesis reaction.
<h3>What are synthesis reactions?</h3>
Synthesis reactions are one of the numerous reactions in chemistry. These kinds of reactions involve the combination of two atoms of different elements resulting in the formation of new compounds.
Synthesis reactions are sometimes referred to as combination reactions, simply because they have to do with the combination of two or more atoms of different elements into a single compound.
The different elements that combine are referred to as the reactants while the result of the combination is known as the product.
For example: A + B --> AB
In the illustrated reaction, N2 combined with H2 to form NH3. N2 and H2 gases are the reactants while NH3 is the only product formed from the two reactants.
This is a good example of a synthesis/combination reaction.
