A noble metal is a metal that resists oxidation and does not corrode (i.e: rust). Silver and platinum are great examples since they don't rust

How do volcanos such as ojos del salado form?
Ksenya-84 [330]

Answer:

Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt.

Explanation: hot molten rock, ash, and gases escape from the volcano

Verizon [17]
The answer is iii) decreasing the pressure of the system. When the pressure is decreased, the equilibrium will shift to the right because it has 12 moles of gas which is greater than the number of moles of gas on the left side, which is 6 moles. Equilibrium shifting to the side that exerts greater pressure is favored to offset the decrease in pressure.

Pavel [41]

Answer:

<em>Protons: </em>

  • Positively charged particle
  • The number of these is the atomic number
  • All atoms of a given element have the same number of these

<em>Neutrons:  </em>

  • Neutral particles  
  • Isotopes of a given element differ in the number of these
  • The mass number is the number of these added to the number of protons

Explanation:

Protons (<em>positively charged</em>), neutrons (<em>neutral</em>) and electrons (negatively charged) are smaller than an atom and they are the main subatomic particles.  The nucleus of an atom is composed of protons and neutrons, and the electrons are in the periphery at unknown pathways.

The <em>Atomic number</em> (Z) indicates the number of protons (P^{+}) in the nucleus. Every atom of an element have the <em>same atomic number</em>, thus the <em>same number of protons</em>.

The <em>mass number </em>(A) is the sum of the <em>number of protons</em>  (P^{+}) <em>and neutrons</em> (N) that are present in the nucleus: <em>A= Z + N</em>

<em>Isotopes</em> are atoms of the <em>same element </em>which nucleus have the <em>same atomic number</em> (Z), and <em>different mass number (A)</em>, it means the <em>same number of protons</em> (P^{+}) and a <em>different number of neutrons</em> (N). For example, the oxygen in its natural state is a mixture of isotopes:

99.8% atoms with A= 16, Z=8, and N=8

0.037% atoms with A=17, Z=8, and N=9

0.204% atoms with A=18, Z=8, and N=10
