Question
Which statement describing the properties of the different phases of a sample of matter it true? The particles in both the gas and liquid phases are highly ordered and are in close proximity to one another. The particles in the liquid phase are highly compressible because they can slip past one another. The particles in both the solid and liquid phases are free to assume any shape and their nearest neighbors change over time. The solid phase is rigid, even though its constituent particles may vibrate a little depending on their temperature. Localized areas of order can form in the gas phase because the panicles experience significant attractions to one another. Which of the following is NOT a pure substance? sparkling water gold metal oxygen gas water vapor dry ice (solid carbon dioxide) Which of the following is a chemical property of formaldehyde (CH:0)? It is flammable. Il has a density of 1.09 g mL. It is colorless. It dissolves in water. It is a gas at room temperature. If the following arithmetic operations are carried out. how many significant figures should be reported in the answer? 132 + 0.56 + 0.01 >3.33 An irregularly shaped metal object with a mass of 25.43 g was placcd in a graduated cylinder with water. The before and after volumes are shown below. What is the density of the metal''Explanation / Answer
1-d
2-a
3-d
4-d because tre result is 135.9
5-a V=34-25=9ml,m=25.43g;d=m/V=25.43/9=2.826g/cc
