Part 2: Intensive vs. Extensive Properties. Compare the matter. Do they have the same extensive property or the same intensive property? Extensive properties define a quantity. Intensive properties define unique characteristics because of composition. On the line next to the item, • type I for intensive only • type E for extensive only • type B for both if there are common intensive and extensive properties type N for neither if there is no common intensive or extensive property. • Only type the letter. 13 14 15 16 17 18 19 20 21 22 A 10 kg granite rock and a 10 kg basalt rock. 50 liters of water and 20 liters of water. 40 grams of chalk and 30 grams of chalk. 1 kg basketball and 0.10 kg golf ball. 10 liters of hydrogen gas and 10 kg of air. 20 meters of rope and 20 meters of string. 50 grams of clear glass and 30 grams of clear plastic 100 kg human and 50 kg tree. 2 kg polyethylene helmet and 1 kg polyethylene knee pads 40 pounds of zinc and 40 pounds of iron.

Plot the data appropriately on a properly formatted graph. Formatting should include descriptive title, axes labels with units, major grid lines marked, proper scaling, and a best fit line (use a ruler).
Errors of different varieties may arise throughout the course of an experiment. Below, match the different types of errors with their corresponding definitions. Group of answer choices Errors that have an equal chance to be positive or negative. These errors will arise because it is impossible to make any measurement completely exact. Errors that will have a consistent directional bias every time the experiment is carried out. These errors tend to always be positive or negative, meaning over or underestimating, respectively, the true value of the measurement due to experimental limitations. An error that is within the direct control and/or caused by a mistake from the chemist. Options Random error Systematic error Human mistake

In the table below you will find three descriptions of scientists engaging in activities that are part of the scientific method. What are the missing words? missing word? description Antoine burns some charcoal, and a very small diamond (1), and makes that the only product of both reactions is a heavy gas the (carbon dioxide). After studying the chemical reactions of many compounds made of carbon, August discovers a that says carbon always forms 4 chemical bonds to other atoms when it forms a compound. Dmitri discovers that the known chemical elements can be arranged in a pattern of columns and rows, with elements in the same column behaving similarly. But there is no element at a certain place in the pattern, and Dmitri proposes the that an unknown element fits into that spot, and that it will have properties similar to the elements above and below it in the pattern. 0 0 0 5 ?
