Give three examples each of household items that have:

a. different structures and exhibit different properties
b. same chemical make-up composition but a different structure, hence, different properties
c. the same properties but with different chemical composition

(If possible, each example has to have a chemical formula).
Thanks.

See your pos above.

a. Different structures and exhibit different properties:

1. Plastic (Polyethylene): Plastic is a synthetic polymer composed of long chains of repeating ethylene units (C2H4). It has a flexible structure and exhibits properties such as low density, high tensile strength, and resistance to chemicals and moisture.

2. Glass (Silicon dioxide): Glass is an amorphous solid composed mainly of silicon dioxide (SiO2). It has a rigid structure formed by the random arrangement of silicon and oxygen atoms. Glass is transparent, brittle, and does not conduct electricity.

3. Steel (Iron-carbon alloy): Steel is an alloy composed primarily of iron (Fe) and carbon (C). It has a crystalline structure with carbon atoms dispersed within the iron lattice. Steel exhibits properties such as high strength, hardness, and excellent tensile and thermal conductivity.

b. Same chemical makeup composition but a different structure, hence, different properties:

1. Graphite and Diamond (Carbon): Both graphite and diamond are composed of carbon atoms, but they have different atomic arrangements resulting in distinct structures and properties. Graphite has a layered structure where carbon atoms are bonded in hexagonal rings, creating a soft, black, and conductive material. Diamond, on the other hand, has a three-dimensional network structure with each carbon atom bonded to four neighboring carbons, resulting in its hardness, transparency, and lack of electrical conductivity.

2. Amorphous and Crystalline SiO2 (Silicon dioxide): Silicon dioxide can exist in two different structures - amorphous and crystalline. Amorphous SiO2, such as fused quartz, lacks long-range order in its atomic arrangement, resulting in a transparent, low-density material that is resistant to thermal shock. Crystalline SiO2, known as quartz or crystal, has a well-defined lattice structure and exhibits piezoelectric properties, optical transparency, and a higher density compared to amorphous SiO2.

3. High-density and Low-density Polyethylene (Polyethylene): Polyethylene is a polymer composed of repeating ethylene units (C2H4). Depending on the polymerization process, different molecular structures can be created, resulting in varying properties. High-density polyethylene (HDPE) has a highly branched structure, resulting in a dense and rigid material with high melting point and chemical resistance. Low-density polyethylene (LDPE), on the other hand, has a more linear structure with longer chain lengths, making it less dense, more flexible, and having a lower melting point.

c. The same properties but with different chemical composition:

1. Vinegar (CH3COOH) and Lemon Juice (C6H8O7): Both vinegar and lemon juice are acidic substances used in cooking, cleaning, or as condiments. Vinegar is made up of acetic acid (CH3COOH), while lemon juice contains citric acid (C6H8O7). Both acids have sour taste and exhibit similar acidity, which gives them the ability to break down certain substances, act as preservatives, or enhance flavors.

2. Sugar (C12H22O11) and Aspartame (C14H18N2O5): Sugar, known as sucrose, and aspartame are sweetening agents used in food and beverages. Sugar is a natural carbohydrate with a complex molecular structure composed of glucose and fructose units. Aspartame, an artificial sweetener, is composed of the chemicals aspartic acid and phenylalanine linked with a methyl ester group. Despite their different compositions, both sugar and aspartame have similar sweet taste properties.

3. Hydrogen Peroxide (H2O2) and Sodium Hypochlorite (NaClO): Hydrogen peroxide and sodium hypochlorite are both commonly used as disinfectants. Hydrogen peroxide is a chemical compound composed of two hydrogen atoms and two oxygen atoms, while sodium hypochlorite is a compound containing sodium, chlorine, and oxygen atoms. Despite their different compositions, both substances exhibit similar antiseptic and oxidizing properties, allowing them to kill bacteria and viruses.
