Answer:
A is on an island arc,
B is in the Andes
Explanation:
The subduction region is referred to as the subduction zone. When a plate slips underneath another, it forms a trench. Earthquakes resulting from the plate panelling often result in magma spilling across the underwater volcano trench. Island arcs are vast chains of active volcanoes with strong seismicity located along the converging tectonic plate borders. Much of the islands arcs emerge from the oceanic crust and also have originated from fall of the lithosphere into the mantle across the subduction zone. In the Andes mountain range, Under the South American plate the Nazca plate is subducting.
Because they react, hope this helps
Answer:
row 1, volume decreases when pressure increases
Explanation:
To solve such this we must know the concept of chemical reaction. Therefore the correct option is option C that is the properties and identity of the reacting substances.
<h3>
What is chemical reaction? </h3>
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
A change in the properties and identity of the reacting substances means that a chemical reaction has occurred.
Therefore the correct option is option C.

Clearly, the acid is in deficiency ; i.e. it is the limiting reagent, because the equation above specifies that that 2 equiv of HCl are required for each equiv of metal.
So if
