The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal, cutting the straw caused the gases to not have to go as far, and meet in the middle.
The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more lose than the particles in a solid but not less than a gas.

The two hazardous materials being used are Ammonia and Hydrochloric acid. Goggles, aprons, and gloves are used for protection for eyes, skin, and clothing against the chemicals in this lab.
1. Put on goggles, apron, and gloves. 2. Find all materials for experiment (Ammonia, Hydrochloric acid, test tubes, Q-tips, ect.) 3. Put straw on top of tape to secure it. 4. Open Ammonia under the hood. 5. Take Q-tip and dip it into the ammonia 6. Open Hydrochloric acid under the hood 7. Take Q-tip and dip it into the hydrochloric acid 8. Place one Q-tip on one end of the test tube and the other Q-tip on the other end 9. Making sure the straw is stable, insert one Q-tip into one side of the straw and the other Q-tip into the other side. 10. A ring should appear, document what you see.
Our group will be manipulating the length of the straw in order to move the ring to the center.
The straw was cut to 8 cm long. It was about 3 cm from the ring to each Q-tip.
a)Where did the solid (ring) come from? What would you consider to be the reactants?
-The solid ring came from the chemical reaction between the ammonia and the hydrochloric acid. The chemicals
