Answer:
synthesis
Explanation:
The reaction equation properly written is shown below:
4Al + 3O₂ → 2Al₂O₃
A synthesis reaction is a form of combination of atoms. It involves the formation of a single product from two or more reactants.
Decomposition is the formation of two or more products from a single reactant.
Single replacement is a reaction in which one substance is replacing another.
In double displacement, there is an actual exchange of partners to form new compounds.
Answer is: <span>lumps os sugar dissolving in water.
Sugar has very good solubility in water and it dissolves readily, which is </span><span>example of a physical change.
</span>Gibbs free energy (G) determines if reaction will proceed
spontaneously, if ΔG is negative, reaction is spontaneous <span>(ΔG = ΔH - T·ΔS).
</span>In other examples, reactions are spontaneous in reverse way, for example spontaneous is forming sodium chlorine from sodium metal and chlorine gas, but not sodium chloride forming sodium metal and chlorine gas, because a lot of energy is needed for that reaction.
The moon is what makes currents so if there was no moon there would be no current in our oceans. The way it makes currents is from the gravitational pull.
