While idly tossing some keys from hand to hand one day, your friend Laila (an expert chemist) says this: "Metal sulfides roasted with oxygen produce the corresponding oxide and sulfur dioxide gas."
Using Laila's statement, and what you already know about chemistry, predict the products of the following reaction.
Be sure your chemical equation is balanced!

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
