Is there a relationship between the locations of earthquake, volcanoes, and plate boundaries? If so, describe the relationship.
Naddik [55]

Answer:

and earthquake epicenters are related to tectonic plate boundaries. causes Earth's plates to move. Most volcanoes and earthquakes are caused by the motion and interaction of Earth's plates. The way Earth's plates interact at boundaries is an important factor in the locations of earthquakes and volcanoes

What are the ionic bonds
zhuklara [117]

Explanation:

Ionic bonds are bonds formed as a result of the electrostatic attraction between two species.

  • This bond type is an interatomic bond.
  • It forms when two specie with a large electronegative difference between them combines.
  • This is usually a metal and a non-metal.
  • The metal loses its valence electrons and becomes positively charged.
  • The non-metal gains the electron and becomes negatively charged.
  • An electrostatic attraction between the two specie leads to the formation of an ionic bond.
  • They are solids with a high melting point.
  • They are soluble in polar solvents.

Consider the reaction when aqueous solutions of potassium hydroxide and ammonium nitrate are combined. The net ionic equation fo
Reil [10]

Answer: OH^-(aq)+NH_4^+(aq)\rightarrow NH_3(g)+H_2O(l)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

KOH(aq)+NH_4NO_3(aq)\rightarrow KNO_3(aq)+NH_3(g)+H_2O(l)

The equation can be written in terms of ions as:

K^+(aq)+OH^-(aq)+NH_4^+(aq)+NO_3^-(aq)\rightarrow K^+(aq)+NO_3^-(aq)+NH_3(g)+H_2O(l)

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The ions which are present on both the sides of the equation are potassium and nitrate ions and hence are not involved in net ionic equation.

Hence, the net ionic equation is :

OH^-(aq)+NH_4^+(aq)\rightarrow NH_3(g)+H_2O(l)

How is it possible to have thousands of different proteins when there are only 20 different amino acids?
STatiana [176]
Hi there!

Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins. 

In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.
