Answer:
It depends on the temperature under earth's surface for the land movement on the surface (for example earthquakes happen from the pressure and movement of tectonic plates). When gravity pulls down rocks inside the layers a new seafloor spreads on the surface.
Explanation:
Answer:
Yes, except for one thing.
Explanation:
The numbers are correct, however, the SA/volume ratio does not have units because the cm² cancels out.
Mineral crystals are divided into six mineral crystal systems based on geometry and angles between axes.Crystals can be didvided into categories of habit the crystals is the appearance in nature.
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.
Urea (CH4N2O), bi carbonate ion (HCO-3), creatinine, bilirubin are the ammonia containing products, are eliminated by kidneys through urine by a process of transamination.
Breakdown of amino acids results in formation of ammonium ions.
The elimination or excretion of urea is called ureotelism.
