Concept explainers
(a)
Interpretation:
Blood has to be classified as a pure substance or a mixture.
Concept Introduction:
Matter can be classified into two type’s namely pure substance and mixture.
Pure substance: A single component that has a constant composition, irrespective of the
Example: Water, sugar etc.
Mixture: A mixture consists of more than one substance and the composition of a mixture is dependent on the sample. The separation of mixture into its components can be done by physical changes.
(b)
Interpretation:
Ocean water has to be classified as a pure substance or a mixture.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
A piece of wood has to be classified as a pure substance or a mixture.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
A chunk of ice has to be classified as a pure substance or a mixture.
Concept Introduction:

- Which of the following represent physical properties or changes, and which represent chemical properties or changes? You curl your hair with a curling iron. You curl your hair by getting a “permanent wave” at the hair salon. Ice on your sidewalk melts when you put salt on it. A glass of water evaporates overnight when it is left on the bedside table. Your steak chars if the skillet is too hot. Alcohol feels cool when it is spilled on the skin. Alcohol ignites when a flame is brought near it. Baking powder causes biscuits to rise.arrow_forwardContainer A and Container B were filled completely with chicken powder. The total mass of 1/3 of the chicken powder in Container B and 1/11 of the chicken powder in Container A was 570 g. If 5/11 of the chicken powder in Container A was poured out, the total mass of the chicken powder in both containers became 2.28 kg. How much chicken powder was in (a) Container A in grams? (b) Container B in grams?arrow_forwardYou are given a hammer, a battery, a bulb, wires and switch.(a) How could you use them to distinguish between samples of metals and non- metals?(b) Asses the usefulness of these tests in distinguishing between metals and non-metals?arrow_forward
- A sample of tap water contains 1.95 x 103 ppm CaCO3(aq). Assuming the density of tap water is 1.00g/mL, calculate the mass of CaCO3 in 2.00 L of water.arrow_forwardSoft wood chips weighing 17.2 kg are placed in an iron vessel and mixed with 150.1 kg water and 22.43 kg sodium hydroxide. A steel lid seals the vessel, which is then placed in an oven at 250°C for 6 hours. Much of the wood fiber decomposes under these conditions; the vessel and lid do not react.(a) Classify each of the materials mentioned as a substance or mixture. Subclassify the substances as elements or compounds.(b) Determine the mass of the contents of the iron vesselafter the reaction.arrow_forward4.) List each as being a physical or a chemical property: copper sulfate is blue, iron is a solid, water melts at 0°C, gasoline is flammable, magnesium reacts with acid, salt is soluble in water.arrow_forward
- Classify each change as physical or chemical. (a) the rusting of iron(b) the evaporation of fingernail-polish remover (acetone) from the skin(c) the burning of coal(d) the fading of a carpet upon repeated exposure to sunlightarrow_forward60. When tin comes in contact with the oxygen in the air, tin(IV) oxide, SnO2, is formed. Sn(s) + O2(g) SNO2(s) A piece of tin foil, 8.25 cm × 21.5 cm × 0.600 mm (d = 7.28 g/cm³), is exposed to oxygen. (a) Assuming that all the tin has reacted, what is the mass of the oxidized tin foil? (b) Air is about 21% oxygen by volume (d = 1.309 g/L at 25°C, 1 atm). How many liters of air are required to completely react with the tin foil? |Darrow_forwardClassify each item as an element or a compound: (a) the gas inside a helium balloon; (b) table sugar; (c) the rust on an iron nail; (d) aspirin. All elements are listed alphabetically on the inside front cover.arrow_forward
- Sodium and potassium are both shiny metals in pure form, but corrode rapidly in the presence of oxygen and humidity to form compounds. Does this fact describe a physical or chemical property of these two metals?arrow_forwardWhich of the following would be heterogeneous? A mixture of sand and water. A mixture of copper and tin. A mixture of salt and water. A mixture of raisins and peanuts.arrow_forwardClassify each of the following as a compound, a homogeneous mixture, or a heterogeneous mixture: (a) distilled water; (b) gasoline; (c) beach sand; (d) wine; (e) air.arrow_forward
