Carbon can react with oxygen to form carbon dioxide. Which of the following statements about this chemical change is true?
This is an oxidation reaction.
How can one determine the oxidation number of an element in a chemical compound?
To determine the oxidation number of an element in a chemical compound, you need to follow these steps: Identify the element in the compound. Determine the common oxidation states for that element. Assign the oxidation number based on the compound's overall charge and known rules for assigning oxidation numbers. By following these steps, you can accurately determine the oxidation number of an element in a chemical compound.
What does oxidation mean in terms of electrons?
Oxidation refers to the loss of electrons by a molecule, atom, or ion during a chemical reaction. It results in an increase in the oxidation state of the species undergoing oxidation.
In the following compound al2o3 aluminums oxidation number is plus 3 and oxygen's oxidation number is?
-2
How does the oxidation number indicate if an electron will be lost or gain by the bond in an atom?
Oxidation number describes gain of electrons. It involves addition of oxygen and removal of hydrogen.
Which of the following describes what takes place when iron (Fe) is oxidized to Fe2 ions?
Iron (Fe) undergoes oxidation when it loses electrons to form Fe2+ ions. This process involves the loss of electrons by iron atoms to form Fe2+ ions, which have a 2+ charge. The iron atoms are oxidized from an oxidation state of 0 to an oxidation state of +2 when they lose electrons.
How does the oxidation state of 0 change in the following reaction?
The oxidation state of an element with oxidation state 0 cannot change, as it already has a balance of electrons.
Which of the following represent waste products of oxidation?
carbon dioxide, water, energy
What is the oxidation state of Cl in the following ion ClO?
The oxidation state of Cl in ClO is +1, because oxygen usually has an oxidation state of -2 in compounds, so Cl must have an oxidation state of +1 to balance the charge of the ion.
Which element decreases its oxidation number in the following reaction?
An element that decreases its oxidation number in a chemical reaction is undergoing reduction. In the given reaction, the element that is reduced is the one that gains electrons and decreases its oxidation number.
which of the following elements is most likely to have an oxidation state of +2?
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
What isThe oxidation number of mn in kmno4?
The oxidation number of Mn in KMnO4 is +7. This is because oxygen (O) is typically assigned a -2 oxidation state, with the total oxidation state of the compound being 0. By following the rule that the sum of oxidation states in a compound is equal to the charge of the compound, we find that Mn is in the +7 oxidation state in KMnO4.
