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.

- In 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_forwardEthylene glycol, C2H6O2, is an ingredient of automobile antifreeze. Its density is 1.11 g/cm3 at 20 C. If you need 500. mL of this liquid, what mass of the compound, in grams, is required?arrow_forwardThe label on a bale of mulch indicates a volume of 1.45 ft3. The label also states that the mulch in the bale will cover an area of a garden 6 ft 6 ft to a depth of 1 in. Account for the discrepancy in the given volumes.arrow_forward
- A solution is prepared by dissolving table salt, sodium chloride, in water at room temperature. a Assuming there is no significant change in the volume of water during the preparation of the solution, how would the density of the solution compare to that of pure water? b If you were to boil the solution for several minutes and then allow it to cool to room temperature, how would the density of the solution compare to the density in part a? c If you took the solution prepared in part a and added more water, how would this affect the density of the solution?arrow_forwardThe density of ethylene glycol (anti-freeze) is 1114 kg/m3. How much mass (in kilograms) of this substance is contained in a can (cylinder) of diameter 15 cm and height 25 cm? (The volume of a cylinder is).arrow_forwardThe total weight of copper in a vehicle ranges from 15 kilos for a small car to 28 kilos for a luxury car. As a material scientist you are analyzing a luxury car that has 30 kilos of copper. What does this indicate about the car’s performance? Where is copper (Cu) likely to be located in the car? Discuss the physical and chemical properties of copper in your answer.arrow_forward
- he distance between atoms is sometimes given in pico-meters, where 1 pm is equivalent to 1 × 10^–12 m. If the distance between the layers of atoms in a particular compound is given as 568 pm, what is the distance in cm?arrow_forwardA manufacturer of paint claims that a gallon (3.78L) of latex paint can cover 365 ft2 of the surface of a wall in a single coating. The paint manufacturer also claims that one single coating of an entire wall will be 3.40 mm thick. Is this a case of false advertising? Yes or No? Elaborate your answer by providing a calculation. You may use the following conversions: 12 in = 1 ft, 2.54 = 1 inarrow_forwardWhich substance can be separated by filtration? A. Compound B. Element C. Mixture D.
