Marla's science teacher suggest that she use magnesium ribbon,a kind of metal that really reacts with acid.The acid she will use is hydrochloric acid HCI (Muriatic Acid).Marla's experiment uses three test tubes. Each test tube has the same amount of acid,in the test tube A she will drop a piece of magnesium ribbon,1cm in length and measure the time it will take for the ribbon to completely disappear. In test tube B,she will put a 3cm long magnesium ribbon and time the reaction. In test tube C, she will use a 5 cm long magnesium ribbon. Marla will repeat the experiment three times. 13.what is the problem in the situation 14.write hypothesis 15.Which is the independent variable 16.How about the independent variable 17.write your conclusion

13. What are the elements that cause each experiment to have a non-specific time reaction while being performed with the same materials in three trials?
14. The different lengths of magnesium ribbon were dissolved in muriatic acid over a period of time, despite the fact that each size was done in three trials, thus there is no set time to see the reaction.
15. The independent variable is the various lengths of magnesium placed within the test tube containing muriatic acid.
16. While the dependent variable is the combination of magnesium ribbon and muriatic acid, the magnesium ribbon dissolves in an unspecified amount of time due to the chemical reaction that muriatic acid contains.
17. Because of the three trials conducted, I discovered that the reaction of muriatic acid is dependent on the lengths of each magnesium ribbon, but there is no specific period of time required in three trials because there are some factors that must be considered to dissolve the given material and the liquid content quickly. And I believe this is due to the temperature of our environment and the way in which we integrated those elements in the chemical experiment.
