Describe how to determine the oxidation number of sulfur in<br> SO₃²⁻
Leya [2.2K]

So, the Oxidation state of S in SO₃²⁻ is +4.

Sulfite ion is the ion depicted.

The oxygen atoms in the ion are currently each in the oxidation state of 2.

The charge of the same entity to which they belong is determined by the sum of the oxidation states of all the atoms in a molecule, ion, or other entity.

Let's say that the sulfur is in the "x" oxidation state.

So,

x + [3×(−2)] = −2.

∴ x + (−6) = −2.

∴x = +4.

S thus has an oxidation state of +4 in SO₃²⁻.

<h3>How do you determine an ion's oxidation number?</h3>

For simple ions, the charge of the ion is equal to its oxidation number. For instance, the sodium ion, Na+, has an oxidation number of 1, while the chlorine ion, Cl-, has an oxidation number of -1. In combinations with nonmetals like CH4, NH3, H2O, and HCl, hydrogen has an oxidation number of one (+1).

<h3>What is an oxidation number?</h3>

An oxidation number, which reflects the general distribution of electrons among the bonded atoms in a molecular compound or molecular ion, is assigned to each atom in a molecular compound or molecular ion.

<h3>What is the general rule for assigning oxidation numbers? </h3>

The connected atom's oxidation number is a representation of the charge that would exist if its electrons were transferred from the connection to the atom of a more electronegative element.

Which statement about a negatively charged object is true? A. It has more electrons than protons. B. It has more protons than el
Llana [10]

The answer to your question would be A; it has more electrons than protons

When trying to identify negatively or positively charged objects, you have to think about the charges of the sub-atomic particles, in this case the protons, electrons and neutrons.

Electrons= negative overall charge

Protons= positive overall charge

Neutrons=neutral overall charge

therefore, if an object is negatively charged, it has to have more electrons than any other sub-atomic particle and hence the answer is A.

If 78.4 grams of aluminum metal react with excess hydrochloric acid, how many grams of hydrogen gas can be produced?2al + 6hcl y
qaws [65]
Answer is: 8,7g.
Chemical reaction: 2Al + 6HCl → 2AlCl₃ + 3H₂.
m(Al) = 78,4g.
n(Al) = m(Al)÷M(Al) = 78,4g ÷ 27g/mol = 2,9 mol.
n - amount of substance.
from reaction: n(Al) : n(H₂) = 2 : 3.
2,9mol : n(H₂) = 2 : 3.
n(H₂) = 4,35 mol.
m(H₂) = n(H₂)·M(H₂) = 4,35mol · 2g/mol = 8,7g.
