Biology
1 answer:
mafiozo [28]3 years ago
5 0

Answer:

C. Two oxygen atoms

General Formulas and Concepts:

<u>Types of Bonds</u>

  • Covalent Bonds - forms between 2 non-metals
  • Ionic Bonds - forms between a non-metal and a metal
  • Metallic Bonds - forms between 2 metals

Explanation:

Any metal forming a compound with an non-metal is an ionic bond. Therefore, A and D are incorrect.

  • Fe (Iron) is a Transition Metal forming an ionic bond with O (Oxygen), a non-metal.
  • Na (Sodium) is a Alkali Metal forming an ionic bond with Cl (Chlorine), a non-metal.

Any 2 metals forming bonds with each other is a metallic bond. Therefore, B is incorrect.

  • Na forms a metallic bond with Na.

Any 2 non-metals forming bonds with each other is a covalent bond. There are 2 types of covalent bonds: non-polar and polar.

  • O forms a covalent bond with O.

Therefore, our answer is C.

In plant cell what does the vacuole do
photoshop1234 [79]
<span>I found this on a website..... Hope this helped :)

"In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food."</span>

How does one prevent such a fire from happening​
valentina_108 [34]

Answer:

water

Explanation:

Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material. It simply cannot oxidize any further so it will not “burn”. This smothers the fire. The same thing would happen if you used the ashes that remained after a completely spent fire. Or, as I mentioned before, CO2.
