Create a hypothesis, design an experiment the list varies really
B) Morrison and Franscioni's research done to create the Frisbee.
Answer:
The correct answer is the charges of the positive and negative copper ions cancel each other out.
Explanation:
A copper metal having no net charge means that it is a neutral atom. A neutral atom means that total number of protons is equal to the total number of electrons.
If the element is oxidized, then it's oxidation number would increase.
Let's say we have the following reaction.
2H2O --> O2 + 2H2
To the left, the oxidation number of O is -2, as it is bonded to two H, which is always H+. To the right, we have O2, and all gases have a oxidation number of 0 (zero). We say that O has been oxidized.
