The explosion of gunpowder is a form of what chemists refer to as a redox (reduction/oxidation) reaction.
combustion
Sodium (Na) has been reduced.
This redox reaction also requires an acid as H2SO4 , the overall reaction is.... 5H2C2O4 + 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 10CO2 +8H2O
They are both redox reactions involving reacting oxygen with a fuel (glucose), generating energy in the process. If you are familiar with the chemical definition of a combustion reaction, it can be seen that the overall equation of cellular respiration is exactly the same as the chemical reaction for burning glucose in air. However, even though the overall equation is the same, the actual process of cellular respiration is much more controlled than regular combustion (otherwise we'd all be burning inside our cells).
Sn(4+) and 2 (SO4)2-
The standard equations based on glucose in a redox reaction. Photosynthesis: 6CO2 + 6H2O --> C6H12O6 + 6O2 ----------------------------------------- Cellular respiration: C6H12O6 + 6O2 --> 6CO2 + 6H2O -----------------------------------------
phenanthroline is used as a redox indicator
yes it does because if it is an redox reaction then something has to be getting reduced of oxygen, therefore the equation must contain oxygen in some type of form somewhere. Sorcha :)
Cu ----> Cu 2+ + 2e-
Auto-redox reaction in which the oxidation number of an atom within a molecule changes as the compound changes on each side of the equation.
To complete the balanced redox reaction, you simplify the equation by removing common elements on both sides.
Hi
This is far to be a rule for this titration.
if it is a redox reaction sometimes you can add water to help balance the equation
