In which location would an ocean ridge most likely be located
Nastasia [14]
An ocean ridge is an underwater mountain system which is the result of tectonic plate movement. Its formation involves two processes: ridge-push and slab pull. The former occurs when the growing bulk of the ridge pushes the rest of the tectonic plate away from the ridge. Oftentimes, they go towards a subduction zone. In this zone, the latter, which is the slab pull comes into effect. This is the weight of the tectonic plate subducted or pulled down below the overying plate tagging along the rest of the plate behind it. 

They are generally located halfway between two continents.

Ionic compounds are good good electricity and heat conductors, because ionic compounds have mobile ions (cations and anions) that are able to transfer electrical charge.

In second reaction, magnesium is oxidized from oxidation number 0 to +2 and  hydrogen is reduced from +1 to 0 (hydrogen gas).
