Answer:
Higher melting and boiling points signify stronger noncovalent intermolecular forces. Consider the boiling points of increasingly larger hydrocarbons. More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points.
Answer:
Magnitude determines the size and how strong force is.
Answer:
Cr 6+ & SO4 2-
Explanation:
Sulfate is a polyatomic ion that has a charge of 2-. There are three of them in the chemical formula so it equates to a 6- total charge. Thus, chromium must have a 6+ charge to give the compound a neutral charge.
Explanation:
The visible light is a part of the electromagnetic spectrum with the range of 400nm to 700nm.
Visible light is made up of all the colors we can perceive.
- The electromagnetic spectrum is a series of radiation.
- The most energetic have the highest frequency and lowest wavelength.
- The visible light is part of the spectrum.
- It is the part of the spectrum that allows for sight.
Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA
