How is an oxidation half-reaction written using the reduction potential chart?
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.
What does the word anaerobic mean?
anaerobic means no oxygen it is the opposite of aerobic.
Why burning metal means having reaction with oxygen?
Heating a metal in air, which comprises of about 21% oxygen, using an open flame at sufficiently high temperature can possibly cause a reaction with oxygen. Sodium burns with a brilliant yellow light to form an ionic sodium oxide. Magnesium burns with a bright white light to form a MgO. Metals exhibit strong metallic bonding(electrostatic attraction between a lattice of positive ions and a sea of delocalised electrons) and therefore require high amounts of energy to break. By burning a metal using a normal flame, reaction with oxygen is more likely to occur than to melt the metal, i.e. the latent heat of fusion is too high.
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
Why is carbon dioxide used to put out a fire?
Fire is the result of a combustion reaction, where a carbon based compound reacts with oxygen to create water, CO2 and sometimes other substances. By using CO2 on a fire, it pushes out any oxygen that would otherwise feed the fire and ends the reaction, or puts out the fire. Because it is heavier than air and non-flammable, so it displaces the air and smothers the fire.
What does the oxidation of hair color do?
When using a permanent hair color, the mixing of two chemicals, peroxide and ammonia with oxygen, creates a chemical reaction called oxidation. Oxidation opens up the cuticle layer of the hair which allows the hair color to lift and deposit color into the hair.

When does a redox reaction produce electricityOnly when an electrical device is attached Whenever electrons are transferred between atoms When electrons are transfered and a pathway for electrons is providedWhenever a pathway for electrons is provided?
A redox reaction contain oxidation and reduction half reaction you can prove it by using oxidation numbers
What is swern oxidation?
Swern oxidation is a type of chemical reaction that occurs in chemistry. It takes a primary alcohol and converts it to a ketone or aldehyde using DMSO or COCI2, along with an organic base.
Which component becomes oxidized in the following chemical reaction 4FE plus 3 O2 equals 2 Fe2O3?
Fe is oxidised. Oxidation can be identified in 3 main ways:Loss of electronsGain in OxygenLoss of HydrogenIn the above, elemental iron gains oxygen so it is oxidised. Some elements such as oxygen and hydrogen are taken to have a fixed oxidation state when in a compound. For Oxygen it is -2 and Hydrogen it is +1. An element by itself has no oxidation state, so it is taken to be 0. Using this you can calculate the oxidation state of the iron. Given that there are 3 oxygen ions in Fe2O3, so 3 x -2 = -6 oxidation state. Given that Fe2O3 is not charged a +6 charge is required to balance the -6. So this +6 is divided across the 2 iron ions to have +3 charge each. So the overall oxidation state change for iron is from 0 to +3.
Using the Gibbs free energy equation what is the temperature range for which the oxidation of lead is spontaneous?
The reaction is spontaneous below 554.8/0.1975 K.
