Make a drawing, based on the kinetic-molecular theory and the ideas about atoms and molecules presented in this chapter, of the arrangement of particles in each of the cases listed here. For each case, draw 10 particles of each substance. It is acceptable for your diagram to be two dimensional. Represent each atom as a circle, and distinguish each different kind of atom by shading.
(a) a sample of solid iron (which consists of iron atoms)
(b) a sample of liquid water (which consists of H2O molecules)
(c) a sample of water vapor

- Table salt from the beaker on the left in the photograph is added to water, forming the solution on the right of the photo. If you want to separate the mixture, would the distillation apparatus in figure 2-16 or the filtration apparatus in figure 2-17 be the better choice? Explain.arrow_forwardWhat is the main difference between electrostatic forces and gravitational forces? Which is more similar to the magnetic force? Can two or all three of these forces be exerted between two objects at the same time?arrow_forwardWhat properties distinguish solids from liquids? Liquids from gases? Solids from gases?arrow_forward
- Suppose someone emptied ball bearings into a container of salt. Could you separate the ball bearings from the salt? How? Would your method involve no change, be a physical change, or be a chemical change?arrow_forwardYou receive a mixture of table salt and sand and have to separate the mixture into pure substances. Explain how you would carry out this task. Is your method based on physical or chemical properties? Explain.arrow_forwardIn the following scenario, identify which of the statements represents a theory, law, or hypothesis. (a) A student exploring the properties of gases proposes that is she decreases the volume of a sample of gas then the pressure exerted by the sample will increase (b) Many scientists over time have conducted similar experiments and have concluded that pressure and volume are inversely proportional. (c) She proposes that the reason this occurs is that if the volume is decreased, more molecules will collide with a given area of the container walls, causing the pressure to be greater.arrow_forward
- What are the answers in the gaps?arrow_forwardA metal object of an irregular shape has a mass of 31.5 grams. When the metal is added to water in a graduated cylinder, the volume of water increases from 5.28 mL to 7.61 mL. (A) How much water does the metal displace? (B) Calculate the density of the metal. (C) Is the metal made of platinum? Explain. (Hint: the density of platinum = 21.4 g/cm³)arrow_forwardIdentify each physical property and physical mentioned in each of these statements. Also identify the qualitative and quantitative information given in each statement. (a)The blue chemical compound azulene melts at 99°C (b) The white crystals of table salts are cubic . (c) A sample of lead has a mass of 0.123 g and melts at 327°C (d) Ethanol is a colorless liquid that vaporizes easily: it boils at 78°C and its density is 0.789 g/mL.arrow_forward

How many times can you divide evenly a 893.4 cm long piece of copper wire until it is reduced to two separate copper atoms? (Assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other.
