How does a battery work, you might ask? Well even if you don’t care, you’re gonna know anyways.

-terminals: two ends of a battery, marked positive and negative
-anode: negative electrodes
-cathode: carbon positive electrode
-electrolyte: allows electric charge to flow (different batteries have different electrolytes)
-collector: conducts charge to outside of battery and through load
-volt: energy per unit of charge
-current: rate of flow of electric charge; speed (units: ambridge)
-chemical redox reaction: metals lose electrons

Single: reaction in one element replaces another in a compound. (a + bc —> b + ac)

Double: reaction when positive and negative components of 2 compounds change “partners”. (ab + cd —> ad + bc)

A chemical reaction is a process in which one or more substances are changed into others. Chemicals change, forming into a new substance. There are different reactions such as single-replacement reactions, double-replacement reactions, combination reactions, and decomposition reactions.
