According to the law of conservation of matter, we know that the total number of atoms does not change in a chemical reaction and thus mass is conserved. Consider this model of a chemical reaction:
Reactants
Products
+ ?
The Substances
Undergoing Reaction
The Substances
Generated by the Reaction
How many oxygen molecules should be added to the reactants side to obey the law of conservation of matter?

Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
