The features that are shared by the rocks include the melting and cooling of rocks.

<h3>What is a rock? </h3>

It should be noted that a rock simply means a relatively hard naturally occurring mineral material.

Crystals most often form in igneous and metamorphic rocks. The processes that these rocks share that likely promote the formation of crystals is the melting and cooling of rocks.

Which highly reactive gas was probably absent from the Earth's primitive atmosphere? O2 (oxygen gas) water vapor methane carbon
rosijanka [135]
Oxygen gas was most likely absent from Earth's primitive atmosphere.  The current theory is that the Earth's early atmosphere was composed of mainly carbon dioxide and methane due to the high volcanic activity.  Cyanobacteria and their use of photosynthesis was what caused earth's atmosphere to become oxygen enriched.
I hope that helps.

Average atomic masses listed by IUPAC are based on a study of experimental results. Bromine has two isotopes 73 br and81 br, who
ddd [48]

<u>Answer:</u> The average atomic mass of element bromine is 80.4104 amu.

<u>Explanation:</u>

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i .....(1)

  • <u>For _{35}^{79}\textrm{Br}[/tex] isotope:</u>

Mass of _{35}^{79}\textrm{Br} isotope = 78.9183 amu

Percentage abundance of _{35}^{79}\textrm{Br} isotope = 50.69 %

Fractional abundance of _{35}^{79}\textrm{Br} isotope = 0.5069

  • <u>For _{35}^{81}\textrm{Br} isotope:</u>

Mass of _{35}^{81}\textrm{Br} isotope = 80.9163 amu

Percentage abundance of _{35}^{81}\textrm{Br} isotope = 49.31 %

Fractional abundance of _{35}^{81}\textrm{Br} isotope = 0.4931

Putting values in equation 1, we get:

\text{Average atomic mass of Bromine}=[(78.9183\times 0.5069)+(80.9163\times 0.4931)]

\text{Average atomic mass of Bromine}=80.4104amu

Hence, the average atomic mass of element bromine is 80.4104 amu.
