rise in temperature and the effect it has on our global weather patterns
Answer : The electrons in a bond between two iodine atoms are shared equally and non-polar.
Explanation :
Non-polar covalent bond : It is a type of bond that is present between the two similar and different atoms. This type of bond is formed when the electrons are shared equally between the atoms.
This type of bond is termed as non-polar because of the electronegativity difference between the atoms is negligible.
The given molecule 
is formed by the equal sharing of electrons and the bond formed between the iodine-iodine is non-polar due to negligible electronegativity difference.
Therefore, the electrons in a bond between two iodine atoms are shared equally and non-polar.
The Nazca plate is converging with the South American plate.
Explanation:
The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.
This mountain range typifies the geology and geography of the South American continent.
- Along this convergent margin, one plate subducts beneath the other.
- The oceanic plate due to its density goes into the mantle.
- The causes the continent riding to obduct and be forced.
- With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.

Answer:
8×10^(-3) mol/L
Explanation:
The formula for finding the hydrogen ion concentration is...
[H⁺] = 10^-ph
[H⁺] = 10^(-2.1)
[H⁺] = 0.00794...mol/L = 8×10^(-3) mol/L
The answer is to 1 significant digit because the pH has one decimal place.
