That water boils at 100º C and that Ag is a solid at 25 º C are physical properties. B. Chemical properties relate to chemical behavior. C 2 H 2 reacts with O 2 to produce heat, CO 2 and H 2 O is a chemical property. Chemical properties include reactivity, toxicity, oxidizing ability, acidity, etc . V. Accuracy and Precision A. Both refer to measurement. 1. Accuracy refers to level of agreement with some standard and is also related to the quality of the measuring tool. 2. Precision refers to the agreement of replicate measurements of the same sample or event. 2 H O H

Chapter 1 Notes-Chemistry and Measurement Fall 2101 Ebbing and Gammon 9 th Edition Chem 0110 Question: Are measurements of the volume of a sample, 10.31 mL, 10.30 mL, and 10.30 mL accurate? Are these measurements precise? B. Accuracy in a measurement is indicated by the number of significant figures used to quantify the measurement. 1. A 10 g sample (mass) weighed on a crude scale, divided by 3.000 mL water has a density volume mass = to 3.3 g/mL. 2. A density determined by measuring a 10.0000 g sample divided by 3.00 mL is 3.33 g/mL. 3. The number of significant figures in a calculated quantity is limited to the number of significant figures in the least accurate measurement involved.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
