What is the net ionic equation for this reaction? na+(aq) + c2h3o2–(aq) + h+(aq) + cl– (aq) → na+(aq) + cl– (aq) + hc2h3o2(aq)

The correct answer is option (d).

Explanation:

Percentage error=|observed value-true value| 100

According to Mr. Klein each lab team must repeat their experiment until their percent error is 2% or less

The percentage error in team-1 :

Observed value of specific heat of copper =

True value of specific heat of copper =

Percentage error=|observed value-true value| 100 = |0.392-0.385| 100 = 0.7%

0.7% < 2% ,means that team-1 observed value is more accurate.

The percentage error in team-2 :

Observed value of specific heat of copper =

True value of specific heat of copper =

Percentage error=|observed value-true value| 100 = |0.395-0.385| 100 = 1%

1% < 2%,  means that team-2 observed value is less accurate than that of the observed value by team-1.

Since, both errors are less that 2%.Hence, the answer is option (d).
