Last week, we had a test on reactions and stoichiometry. I understand reactions and I know how to do stoichiometry problems. I did not need to use my compostition book to take my test. We did a lab. We mixed 3M of hydrochloric acid and and 3g of sodium carbonate. We boiled this solution and salt was left in the beaker. We had a very small percent error. I think my balance was not a zero before I found the mass of the items. My group's balance was different from the other groups. There was some popping noise when the water was all boiled out and dry. Some white stuff came out of the beaker. I thought the popping noise was interesting.
