Range on a pH scale for acid

Biology
1 answer:
Fantom [35]3 years ago
7 0

Answer:

0 to 14.

Explanation:

The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.

valentinak56 [21]

The right answer is polarity.

In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.

Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).

Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.

Describe the view if you were to stand in the penumbra of a lunar eclipse.
madreJ [45]

From within the Moon's penumbra, a partial solar eclipse can be seen. Like any other opaque objects illuminated by a light source, the Moon and the Earth cast shadows into space as they block the sunlight that hits them. Each shadow has 3 different areas: the umbra, the penumbra, and the antumbra.

Products are what is created during a reaction. What are the three products of cellular respiration
Setler79 [48]

Answer:

The three products of cellular respiration are:

  1. ATP
  2. Water
  3. Carbon dioxide

Explanation:

  • Cellular respiration is the process of breaking down glucose molecules to yield energy in the form of ATP.
  • C6H12O6 + 6O2 → 6CO2 + 6H2O

ATP Production:

  • The first step of cellular respiration, glycolysis, yields 2 net ATP.
  • The second step, Kreb's cycle produces 10 NADH and 2 FADH2 molecules. Both these molecules store energy that is released in the electron transport chain to produce 34 ATP.
  • Therefore, a total of 36 ATP are produced as a result of cellular respiration in eukaryotes.

Carbon dioxide Production:

  • 2 molecules of CO2 are produced during the conversion of pyruvate into Acetyl Co-A by the <em>pyruvate dehydrogenase</em> complex.
  • 4 molecules of CO2 are produced in the Kreb's cycle.

Water Production:

  • Water is produced in the Electron Transport Chain (ETC) by the reduction of oxygen.
