Conclusion
Zinc chloride was created by combining CoCl2 and Zn. We know that it was created by using solubility rules and a balanced reaction. We can be sure that a reaction occurred by the production of a precipitate. Bubbles were also produced which is another way to know that a chemical reaction took place. This experiment could have been improved by using a more precise scale and measurements. Also by using a timer to know exactly how long the solution had been sitting.
