Answer:
2Mg + O₂ ⇒ 2 MgO
Explanation:
When the MgO formation reaction is carried out experimentally, it can be seen that Magnesium a solid that has a metallic luster, when a flame is brought closer so that the oxidation reaction of the metal occurs, it is appreciated that a colored flame is produced white for a few moments (the duration of the flame depends on the initial amount of magnesium) and when the reaction finished, the magnesium became a white solid, opaque and very fragile. This is because Mg reacted with oxygen and magnesium oxide formed, which is the white solid.
Synthesis reactions are those in which two or more reagents combine to obtain a new product compound. The general formula for this type of reaction is:
A + B ⇒ C
In the case of the example of the statement, the reaction form of this synthesis would be:
2Mg + O₂ ⇒ 2 MgO
The equation is matched in such a way that there is the same amount of atoms of each species in both reagents and products, thus respecting the principle of conservation of mass.
Clarification: In the synthesis reaction, oxygen is placed in its molecular form (O₂), because the compound is naturally found, it is a simple substance. Magnesium, on the other hand, is found as a simple substance as atoms.
The reaction between Magnesium and Oxygen produces Magnesium Oxide. The balanced equation is 2Mg + O2 → 2MgO.
In the reaction, Magnesium (Mg) reacts with Oxygen (O) to produce Magnesium Oxide (MgO).
The balanced chemical equation for this synthesis reaction is:
2Mg + O2 → 2MgO
In this equation, there are an equal number of atoms of each type on both sides of the equation, which follows the principle of conservation of mass.

Answer:
Sea floor spreading
Explanation:
In case of a divergent plate motion, two plates move away from another. Due to this motion, there occurs separation of the seafloor, resulting in the addition of new materials to the crust along the mid oceanic ridge. This mid oceanic ridge marks the boundary of separation of the oceanic plates. It often generates deep focus earthquakes and forms volcanoes or chains of volcanic arcs.
Thus, the separation of the two plates under water causes seafloor spreading, and the magma fills the space along the mid oceanic ridge.
Explanation:
solution is neutral because it added water and water is neutral solution
