Chapter 1: Q22E (page 65)

Matter is everywhere around us. Make a list by name of fifteen different kinds of matter that you encounter every day. Your list should include (and label at least one example of each) the following: a solid, a liquid, a gas, an element, a compound, a homogenous mixture, a heterogeneous mixture, and a pure substance.

Short Answer

Expert verified

Steel, Water, Water vapor, Aluminum Foil, Salt, Air, Oil and Water, Baking soda, Soap, Juice, Tea, Vegetable oil, Rusting of Iron, Sanitizer, Utensils.

Step by step solution

01

Step 1. Matter

Matter is known to be a substance with a certain mass and occupies an area by having volume.

02

Step 2. Identifying matters and their kind

  1. Steel - A solid
  2. Water - A liquid
  3. Water vapor - A gas
  4. Aluminum foil - A pure substance
  5. Salt - A compound
  6. Air - A homogeneous mixture
  7. Oil and water - A heterogeneous mixture
  8. Baking soda - A pure substance
  9. Soap - A homogeneous mixture
  10. Juice - A homogeneous mixture
  11. Tea - A liquid
  12. Vegetable oil - A homogeneous mixture
  13. Rusting of Iron - A homogeneous mixture
  14. Sanitizer - A liquid

Most popular questions from this chapter

Identify each of the underlined items as a part of either the macroscopic domain, the microscopic domain, or the symbolic domain of chemistry. For those in the symbolic domain, indicate whether they are symbols for a macroscopic or a microscopic feature.

(a) A certain molecule contains one H atom and one Cl atom.

(b) Copper wire has a density of about 8g/cm3.

(c) The bottle contains 15 grams of Ni powder.

(d) A sulfur molecule is composed of eight sulfur atoms.

When elemental iron corrodes it combines with oxygen in the air to ultimately form red brown iron(III) oxide which we call rust.

(a) If a shiny iron nail with an initial mass of 23.2 g is weighed after being coated in a layer of rust, would you expect the mass to have increased, decreased, or remained the same? Explain.

(b) If the mass of the iron nail increases to 24.1 g, what mass of oxygen combined with the iron?

The density (d) of a substance is an intensive property that is defined as the ratio of its mass(m) to its volume (V).

\(\begin{aligned}{\rm{density = }}\frac{{{\rm{mass}}}}{{{\rm{volume}}}}\\{\rm{d = }}\frac{{\rm{m}}}{{\rm{v}}}\end{aligned}\)

Considering that mass and volume are intensive properties, explain why their ratio, density is intensive.

Indicate whether each of the following can be determined exactly or must be measured with some degree of uncertainty:(a) the number of eggs in a basket(b) the mass of a dozen eggs(c) the number of gallons of gasoline necessary to fill an automobile gas tank(d) the number of cm in 2 m(e) the mass of a textbook(f) the time required to drive from San Francisco to Kansas City at an average speed of 53 mi/h.
