In chemistry we did an experiment which involved magnesium, citric acid and water. We mixed these components together and it made hydrogen. A combustion needs 3 things in order to happen ; a fuel, an oxidizer, and a ignition stimulus.
What do you think happened when we burned our hydrogen balloons?
I think what happened to the balloon's was that since there was hydrogen in it, the hydrogen had a reaction to the fire which caused the loud popping noise. There were so many atoms bumping into each other that made the balloon go crazy.
Update: In this experiment, we mixed water, citric acid and magnesium, filled the balloon with a unstable gas. All atoms have 3 sub-atomic particles called protons, neutrons and electrons. By being able to burn the balloon it made the atoms go all crazy, because it was not stable so a combustion occurred when we put the fire on the balloon |

In the disappering ink lab we measured .1g of phenophthalien. Added 100ml of ethanol and then added 100ml of DL H2O and we dropped 3m NaOH until it was dark red. Then we shook it which changed the pH level to neutral bringing the liquid back to the original clear form.

Ocean Acidification is measured by a pH scale. On the pH scale each step is a factor of ten. 0 would be highly acidic and 14 is highly alkaline. If you increase acidicy the pH is dropping. If you increase alkalinity the pH is going up. pH is a measure of potential. In 1751-1990's the pH decreased from 8.25-8.14 which doesnt seem like a lot but in reality it is because from 6 to 5 the acidic level is decreasing by 10 times than before. CO2 is in the atmosphere and it gets into the ocean. When carbon dioxide is absorbed by seawater it causes a chemical reaction to occur. By that happening it causes the seawater to become more acidic and causes carbonate ions to be less abundant. Ocean acidification is affecting the entire world's ocean, waterways and ravines.
