Which is evidence that the reaction below is a redox reaction? 2na+cl2 -> 2nacl
a. the sodium atom is a pure element as a reactant and becomes part of a compound.
b. two different elements take part is the reaction.
c. oxidation occurs to both elements in the reaction
d. there are no ions in the equation

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

conservation of mass

mass before something happens = mass afterwards
