Chemistry true or false state why easy points?

A REDOX reaction is happening when a flashlight battery is operating.Chemistry true or false state why easy points?
true


read the first paragraph of my sourceChemistry true or false state why easy points?
The half-reactions are:





Zn(s) + 2OH鈭?aq) 鈫?ZnO(s) + H2O(l) + 2e鈭?br>

2MnO2(s) + H2O(l) + 2e鈭?鈫扢n2O3(s) + 2OH鈭?aq)





redox means reduction-oxidation reaction. In this type of reaction electrons are transferred from one chemical species to another. In this case, Zn(s) is oxidized (loses electrons) and MnO2 is reduced (gains electrons). The statement is true.
true
