Concept explainers
(a)
Interpretation:
The tap water has to be identified as homogenous or heterogeneous mixture.
Concept Introduction:
Mixture:
A mixture always contains two or more substances that can be present in varying amounts. The components of a mixture do not lose their identities and may be separated by physical means. There are two types of mixture,
- Homogeneous mixture
- Heterogeneous mixture
Homogeneous mixture:
Homogenous mixture consist of a single phase be it liquid, gas, or solid the chemical composition is the same for any sample of the mixture.
Heterogeneous mixture:
Heterogeneous mixture consist of different phase are not uniform they will not have an identical composition.
(b)
Interpretation:
The carbonated beverage has to be identified as homogenous or heterogeneous mixture.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The oil and vinegar salad dressing has to be identified as homogenous or heterogeneous mixture.
Concept Introduction:

(d)

Is seawatera heterogeneous or homogeneous mixture? Explain.arrow_forward
- A solution made by dissolving sugar in water is homogeneous because the composition is the same everywhere. But if you could look with very high magnification, you would see locations with water particles and other locations with particles of sugar. How can we say that a sugar solution is homogenous?arrow_forward7. State whether each of the following represents a chemical change or merely a physical change:(a) A few grams of sucrose (table sugar) are placed in a small beaker of deionized water; the sugar crystals “disappear,” and the liquid in the beaker remains clear and colorless.(b) A copper statue, over time, turns green.(c) When a teaspoon of baking soda (sodium bicarbonate) is placed into a few ounces of vinegar (acetic acid), volumes of bubbles (effervescence) are produced.arrow_forwardClassify each of the following as a physical change or a chemical change. (a) Touching a lit candle to hydrogen soap bubbles gives an explosion. (b)Heating water in a flask produces moisture on the glass. (c) Combining two colorless solutions gives a yellow solid. (d) Pouring vinegar on baking soda produces gas bubbles.arrow_forward
