Answer:
a. Decomposition.
Explanation:
A combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions may be represented by equations of the following form: X + Y ⇒ XY.
- Decomposition reactions are a type of chemical reaction that involves breaking down a compound into smaller compounds or individual elements.
- A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces other element in a compound.
- A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (action) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Hence, the answer is a decomposition reaction.
Newton's first law of motion is sometimes called the law of inertia. When the forces acting on an object are balanced, the object is either at rest or moving with a constant velocity. Unbalanced forces can cause an object to accelerate or decelerate. Unbalanced forces can also cause an object to change direction.
Answer:
This region of thick, hot crust and mantle extends 1,300 kilometers north and south of the Iceland hotspot and some 1,000 kilometers north and south of the Azores hotspot. Together, the two hotspots appear to be feeding a huge supply of magma to nearly the entire northern segment of the Mid-Atlantic Ridge.
