The reaction 4Al + 3O₂ → 2Al₂O₃ is a synthesis or also called combination reaction because reactants combine to produce a new compound (Option 2).
<h3>What is a synthesis combination reaction?</h3>
In chemistry, a synthesis or combination reaction is any type of chemical reaction in which two or more molecules called reactants combine to produce one or more molecules called products of such reaction.
Therefore, with this data, we can see that a synthesis or combination reaction is a chemical process where two or more molecules combine to produce a new molecule known as a product.

They both use small amouts of nuclar waves
The initial equivalent resistance of the circuit is
which means
Therefore the initial current in the circuit is
When the new resistor of
is added to the circuit in parallel, the new equivalent resistance of the circuit is
from which we find
This means that the equivalent resistance of the circuit has decreased, and the new current is
which means that the current in the circuit has increased.
