In the reaction between bromine and sodium, a bromine atom gains an electron. What ion is formed? Is the bromine oxidized, or is it reduced?
Thank You ^_^
Sodium loses an electron to become a sodium ion, the bromine gains an electron to become the bromide ion. Na is the reducing agent (it is oxidized) while bromine is the oxidizing agent (it is reduced). Loss of electrons is oxidation; gain of electrons is reduction.
Thank You So Much! ^_^
1. Show that a pendulum alayws swings at the same time no matter how long or short the amplitude is. And the time is only a function of the pendulum length.2. Show that the weight of a block submerged is equal to the weight of the volume of water that is displaced.
