Answer:
El ciclo del fósforo es un ciclo biogeoquímico que describe el movimiento de este elemento químico en un ecosistema. Los seres vivos toman el fósforo en forma de fosfatos a partir de las rocas fosfatadas, que mediante meteorización se descomponen y liberan los fosfatos.
Answer:
Substitutional alloys tend to be more ductile than interstitial alloys. true
Interstitial alloys tend to form between elements with similar ionic radii.false
Nonmetallic elements are never found in alloys. false
Explanation:
Substitutional alloys consists components having similar atomic(ionic) radii as well as common bonding characteristics. In interstitial alloys, atoms in interstitial positions must have a much smaller covalent radius than the solvent atoms. Interstitial atoms are generally less ductile than substitutional alloys.
Nonmetals are found in alloys. For instance, carbon is a component of the common alloy called steel.
All particles (atoms and molecules) of matter have kinetic energy because they are always in motion.
A measure of the kinetic energy of particle motion within a substance is temperature. If the particles move faster, they have more kinetic energy, and the substance has a higher temperature
The reactions of the human body are exothermic
Answer:
40
Explanation:
Your trying to find out the meters so your going to divide 3920J by 10 and 9.8
3920/10/9.8
