Use the rules (in order) to assign oxidation numbers to each of the elements in the compounds below.
xz_007 [3.2K]

Answer:

Explanation:

The oxidation number is an integer that represents the number of electrons that an atom receives or makes available to others when it forms a given compound.

The oxidation number is positive if the atom loses electrons, or shares them with an atom that has a tendency to accept them. And it will be negative when the atom gains electrons, or shares them with an atom that has a tendency to give them up.

Chemical compounds are electrically neutral. That is, the charge that all the atoms of a compound contribute must be globally null. That is, when having positive or negative charges in a compound, their sum must be zero.

There are some rules for determining oxidation numbers in compounds. Among them it is possible to mention:

  • Hydrogen (H) has an oxidation number +1 with nonmetals and - 1 with metals.
  • Oxygen (O) presents the oxidation number -2
  • Fluorine F has a unique oxidation state -1

Then:

  • NOF: N+(-2)+(-1)=0 → N=3 → oxidation number of  nitrogen (N) is +3, oxidation number of oxygen (O) is -2 and oxidation number of  fluorine (F) is -1.
  • ClF₅: Cl + 5*(-1)=0 → Cl= 5 → oxidation number of  chlorine (Cl) is +5 and oxidation number of  fluorine (F) is -1.
  • H₂SO₃: 2*(+1)+S+3*(-2)=0 → S=4 → oxidation number of hydrogen (H) is +1, oxidation number of oxygen (O) is -2 and oxidation number of sulfur (S) is +4.

What is the main difference between a homogeneous mixture and a heterogeneous mixture?
Sholpan [36]
The answer is <span>The components of a homogeneous mixture are evenly distributed.

In a homogeneous mixture, all components are evenly distributed. They are known as solutions. In a heterogeneous mixture, components are not evenly distributed. It consists of visibly different components. For example, milk is the homogeneous mixture, you cannot see its particles. But milk and cereals are the heterogeneous mixtures.</span>
