Question

14- The accepted value is 15.63. Which correctly describes this student's experimental data? Trial 1: measurement 15.64; Trail 2: measurement 15.62; Trall 3: measurement 15.61 a) Accurate but b) Precise not accurate c) Both accurate and Neither accurate nor preci not precise precise 15. Which element, when combined with fluorine, would most likely form compound (lonic bondi? a) Fluorine b) Phosphorus C Carbon d sodium ) All are correct

Answer 1

• Accurate is read correct (or close to 1. Valine) • (14 Precise is Repeating (or Repeatable) ) Real Value & 15.63 measured vaker = 18.64 15.62, 15.61 - near to close But Not Repeatable So value an accurate But to Not precise optional
