A chemistry student is recording the electric charges of some atoms. Use the results in the chart to answer the following questions. Atom Electric Charge
Carbon −4
Nitrogen +5
Oxygen −2
Part A:
Write an equation to find the difference in electric charge between the Nitrogen atom and the Oxygen atom.

Part B:
Using the equation you wrote in Part A, what is the difference in electric charge between the two atoms?

A1 forms when an acid is neutralized by a base. 1. salts can be neutral, or in solutions. salts of 2. strong acid–strong base reactions produce solutions with 3. water. salts formed from the neutralization of weak acids or weak 4. bases water. they produce solutions that are acidic or . basic. for example, the ph of a solution at the equivalence point is . greater than for a acid titration. solutions that resist changes in ph are called solutions. the buffer is the amount of acid or base that can be added to a buffer without changing the ph greatly.
