Result of the collision. of two continental plates,such as the Appalachians
Nady [450]

Mountain building

Explanation:

The result of the collision of two continental plates such as the Appalachians is a mountain building process.

The opposite of subduction takes place in such margins.

The Himalayan mountain ranges is also an example of colliding plates.

Instead of subduction taking place, the two plates cannot are less dense than the mantle below and they have to be grind and pull each other up.

Which answer best describes what is happening in the following redox reaction?
erica [24]

Answer:

Iron is oxidized to form rust.

Explanation:

Consider the reaction; 4Fe + 302------>2Fe2O3, we can see that iron is being oxidized to iron III oxide. Rust is the common name of iron III oxide.

Rusting is an electrochemical process, iron rusts when it comes into contact with air and water because electrochemical cells are set up at the surface of contact.

Iron usually functions as the anode in the electrochemical process. This process leads to the formation of iron III oxide. Rust is soft and breaks off easily thereby exposing the metal below the surface to further rusting.

When increased, increases the rate of solution (2 words) not particle size
PilotLPTM [1.2K]

Explanation:

There are quite a number of ways to increase the solubility of substances.

Solution is a homogeneous mixture formed by dissolving a solute in a solvent.

Here are some things that can increase the rate of dissolution;

  • Grinding/pulverizing - helps to increase the surface area for the solvent to react.
  • Stirring - to bring more solvent in contact with the solute intimately.
  • Heating - to facilitate dissolution of solute in solvents.
