Answer:
Letter c. N2
Explanation:
A molecule is a group of two or more atoms of the same element, joined by covalent bonds. The simplest molecules have to atoms like some gaseous elements such as nitrogen (N2), while a compound is a pure substance constituted by atoms of different elements joined through chemical bonds in defined proportions and that can only be decomposed into the elements of origin by chemical reactions.
You are given the molarity of the solution which is 1x10-5 M. Since molarity is moles of solute over liters solution. You could determines the moles.
M=m/V
1x10-5 = m/(2 L)
m = 2x10-5 moles ligand A
We could determine the mass of ligand A by using the molar weight:
2x10-5 mol * 250 g/mol = 0.005 grams of ligand A
I hope I was able to answer your question. Have a good day.
Answer:
When water warms up it expands. At the same time global warming causes polar ice sheets and glaciers to melt. The combination of these changes is causing sea levels to rise, resulting in flooding and erosion of coastal and low lying areas.

Another term would be a monomer which link together to form polymers
