What is chemical formula of sulphuric acid?
H2SO4. In sulphuric acid, the S atom has a valence of 12 electrons. Two of the O atoms are attached to the S atom through double bonds. The other two O atoms are hydroxy ("-OH") oxygen atoms that are attached the S atom through a single bond.
How many oxygen atom are in 5 molecules oh H2so4?
Five molecules of H2SO4 contains 20 atoms of Oxygen
What does the term reduced mean in a chemical reaction?
In a chemical reaction, the term "reduced" refers to a substance gaining electrons or decreasing its oxidation state. This results in a decrease in the number of positive charges on the atom or molecule. Reduced substances are often involved in redox reactions where they act as electron acceptors.
What happens to atoms in a oxidation reduction reaction?
The oxidation state of one atom increases while another decreases.
What is the result of an atom that gains or loses an electron?
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
In the reaction of sodium with oxygen what atom will be reduced?
Oxygen will be reduced in the reaction with sodium because it gains electrons to form the oxide ion (O2-).
How many atoms of sulfur are in the compound H2SO4?
In one molecule of H2SO4, sulphuric acid, there is one atom of sulphur
What is the difference between a balanced and unbalanced equation?
A balanced equation has the same number of each type of atom on both sides of the reaction arrow, obeying the law of conservation of mass. An unbalanced equation does not have the same number of atoms on both sides and thus does not accurately represent the chemical reaction.
What happens when an atom is not oxidized or reduced during a reaction?
When an atom is not oxidized or reduced during a reaction, it means that its oxidation state remains unchanged. This implies that the atom neither gained nor lost electrons during the reaction, maintaining its initial valence state.
What is chemical formula of sulphuric acid?
H2SO4. In sulphuric acid, the S atom has a valence of 12 electrons. Two of the O atoms are attached to the S atom through double bonds. The other two O atoms are hydroxy ("-OH") oxygen atoms that are attached the S atom through a single bond.
How many oxygen atom are in 5 molecules oh H2so4?
Five molecules of H2SO4 contains 20 atoms of Oxygen
Which element is reduced in this reaction 2hcl plus 2kmno4 plus 3h2c2o4-6co2 plus 2mno2 plus 2kcl plus 4h2o?
In the given reaction, the manganese atom changes from a +7 oxidation state in potassium permanganate (KMnO4) to a +4 oxidation state in manganese dioxide (MnO2), indicating that the manganese atom is reduced.
What does the term reduced mean in a chemical reaction?
In a chemical reaction, the term "reduced" refers to a substance gaining electrons or decreasing its oxidation state. This results in a decrease in the number of positive charges on the atom or molecule. Reduced substances are often involved in redox reactions where they act as electron acceptors.
What are the compound for H2SO4?
hydrogen sulfate= H2SO4 is a strong acid
Why is an atom which accepts an electron called reduced instead of oxidized?
An atom that accepts an electron is called reduced because it gains electrons, which leads to a reduction in its oxidation state. In a reduction-oxidation (redox) reaction, the atom that accepts electrons is undergoing reduction, not oxidation.
How can you tell if an element has been reduced?
The reactant that reduces another atom
Which atom in sodium chloride is reduced?
The chlorine atom.
