Answer:
Milk
Explanation:
Typically, the lower a substance is on the pH scale, the higher its acidity is and the higher the H+ concentration is. Conversely, the higher a substance is on the pH scale, the more basic it is and the lower the H+ concentration is. To be considered an acid, a substance has to be below 7 on the pH scale, since 7 is neutral. The highest substance on the pH scale that is still below 7 is milk, with a pH of about 6.5. Therefore, this is the answer. Hope this helps!
Answer:
The correct answer is option D, that is, magic numbers.
Explanation:
The magic number in nuclear physics refers to the number of nucleons, that is, either neutrons or protons, distinctly, such that their alignment results in the formation of complete shells within the nucleus of the atom. As a consequence, atomic nuclei comprising a magic number of neutrons or protons are much more stable in comparison to other nuclei.
The seven most broadly known magic numbers are 2,8,20,28,50,85 and 126.
Answer:
They are made in the Heavens, in Stars.
Explanation:
Answer:
The chemical formula is I2F9
Explanation:
There are 9 H atoms in one molecule, so hydrogen is present in the greatest proportion by number of particles;
The ratio by particles is C:H:O:N = 8:9:2:1.
