No matter how big or little a material is, its properties remain the same. Size, form, color, and mass are the qualities that distinguish a material from non-substances. All of these qualities, including size, shape, color, and mass, can be seen and measured. Some characteristics are physical, while others are chemical. Physical characteristics include mass, volume, density, and color.  Viscosity and solubility are examples of chemical qualities.

If an atom has an electron configuration of 2.8.2, what will it be most likely to bond with?
Kipish [7]

Answer:

B. Two chlorine atoms

Explanation:

This electronic configuration shows that the given atom is magnesium.

Electronic configuration of magnesium:

Mg¹² = 1s² 2s² 2p⁶ 3s²

There are two valance electrons of magnesium that's why it would react with two atoms of chlorine. Chlorine is present in seventeen group. It has seven valance electrons. It required just one electron to get complete octet. While magnesium needed to lose two electrons to get complete octet. That's why two chlorine atoms bonded with one magnesium atom. Thus both would get complete octet.

Mg + Cl₂  →   MgCl₂

________ splits fatty acids into two-carbon units that form acetyl-coa and releases high-energy electrons.
zimovet [89]

The answer is beta oxidation. It is a process in which molecules particularly fatty acids are cracked down in the prokaryotes’ cytosol and in the mitochondria in eukaryotes to produce acetyl-CoA, which goes in the citric acid cycle, <span>FADH2</span>, and NADH which are co-enzymes that are cast-off in the electron transport chain. The major response site is the beta-carbon from the thioester carbon.
