Which of the following is not a theory supporting global warming?
ahrayia [7]

The correct answer is - d. Carbon dioxide is an insignificant greenhouse gas.

To say that the carbon dioxide is an insignificant greenhouse gas is not a theory that is supporting the global warming, not to mention the fact that it is the total opposite.

The carbon dioxide (CO2) is actually the gas the contributes the most to the greenhouse effect. The reason for that is that the CO2 is a gas that has the property to trap the heat, thus the heat instead going back to the space, it is actually remaining in the atmosphere. That results in warmer temperatures on a global scale, as we can witness in the past century with the increasing amounts of CO2 into the atmosphere because of the human activities.

How is the oxidation state of a transition metal determined from the chemical formula ?
Vera_Pavlovna [14]

Answer:

Explanation:

In a chemical formula, the oxidation state of transition metals can be determined by establishing the relationships between the electrons gained and that which is lost by an atom.

We know that for compounds to be formed, atoms would either lose, gain or share electrons between one another.

The oxidation state is usually expressed using the oxidation number and it is a formal charge assigned to an atom which is present in a molecule or ion.

To ascertain the oxidation state, we have to comply with some rules:

  • The algebraic sum of all oxidation numbers of an atom in a neutral compound is zero.
  • The algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to  the charge on the ion.

For example, let us find the oxidation state of Cr in Cr₂O₇²⁻

This would be:  2x + 7(-2) = -2

                          x = +6

We see that the oxidation number of Cr, a transition metal in the given ion is +6.
