what is redox equation? write to quantita tave significance of chemical equation.
Answers
Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
Multiply the half-reactions by the appropriate number so that they have equal numbers of electrons. Add the two equations to cancel out the electrons. The equation should be balanced.
Explanation:
A redox reaction is one in which both oxidation and reduction of elements and compounds takes place simultaneously.
For example:
CuO+H2→ H2O+Cu
Here u can see that copper oxide is reduced to copper and hydrogen is oxidised to form water.
Chemical formulas and chemical equations both have a quantitative significance; the subscripts in formulas and the coefficients in equations represent precise quantities. The formula indicates that a molecule of this substance contains exactly two atoms of hydrogen and one atom of oxygen.
