Corrosion is the process by which iron is oxidized by elemental oxygen. therefore oxygen is the (oxidizing / reducing) agent and (gives / accepts) electrons.

Answers

Answer 1
Answer:

Answer:

Oxygen is the oxidizing agent and accept electrons

Explanation:

  • Corrosion is an example of a redox reaction which involves both reduction and oxidation process.
  • During corrosion a metal loses electrons and becomes oxidized to form a metal ion.  Therefore, oxygen is the oxidizing agent since it undergoes reduction by gaining electrons.
  • Therefore, during corrosion of iron, iron is the reducing agent and gives electrons, while oxygen is the oxidizing agent and accepts the electrons.

What are ionic compounds typically composed of?a metal anion and a nonmetal cation

two metal anions

a metal cation and a nonmetal anion

two nonmetal cations

Answers

ionic compounds are held together by ionic bonds are formed by the transfer of electrons from a metal to a non metal

Ionic bond is formed by the electrostatic attraction between the oppositely charged ions.

metals give out electrons and becomes positively charged. positively charged ions are called cations. so these are called metal cations

the electrons given out are taken in by non metals and become negatively charged. negatively charged ions are called anions. then they are called non metal anions.

so ionic compounds are formed by the electrostatic attraction between metal cations and non metal anions.

therefore ionic compounds are composed of a metal cation and a nonmetal anion
Ionic compounds are typically composed of a metal cation and nonmetal anion.

The cell theory teaches that _____.the basic unit of life is the organism
the basic unit of life is the cell
all cells have the same basic structure
cells are miniature reflections of the organisms from which they are taken

Answers

The cell theory teaches that :

the basic unit of life is the cell
Explanation:

In biology, a scientific theory is that the historical theory, currently universally accepted, that living organisms square measure created from cells, that they're the fundamental structural/organizational unit of all organisms, which all cells come back from pre-existing cells. Cells square measure the fundamental unit of structure all told organisms and conjointly the fundamental unit of the replica.

Answer:

the basic unit of life is the cell

How many covalent bonds can each carbon atom form?

Answers

The covalent bonds present in based on the valence electrons and thus form 4 bonds.

What are valence electrons?

The valence electrons are the number of electrons present on the last orbital of the atom.

The atomic number of carbon is 6, thereby it is given with the electronic configuration 2, 4.

There is the presence of the 4 valence electrons in the carbon atom, and thereby the number of covalent bonds formed by carbon atom is 4.

Learn more about valence electrons, here:

#SPJ2
Carbon can form a maximum of 4 covalent bonds because it has 4 valence electrons i.e. 4 outer electrons. 

What property of an atom determines its general reactivity?

Answers

The Chemical reactivity of metals varies with your eletropositividade, so the more eletropositivo is the most reactive element is metal. The most reactive metals are those that have great tendency to lose electrons and  therefore form positive ions with more ease.

hope this helps!
