Sucrose is a type of sugar that is commonly used as the main ingredient in hard candy. It is a crystalline substance derived from sugar cane or sugar beets. When sucrose is heated and melted, it forms a syrup that can be molded into various shapes and hardens as it cools. This process is used to create hard candy, which is known for its solid and brittle texture. Therefore, it is accurate to say that the main ingredient of hard candy is sucrose.

Citric acid is the correct answer because it is commonly found in sour candies. It is a weak organic acid that gives a tangy and sour taste to foods. Citric acid is naturally present in citrus fruits like lemons, limes, and oranges, which are often used to make sour candies. It is also used as a flavoring agent in many other food and beverage products.

Sugar alcohols are not completely absorbed by the body. While they are partially absorbed, a significant portion of sugar alcohols pass through the digestive system without being fully metabolized. This is because the body lacks the necessary enzymes to break down sugar alcohols completely. As a result, consuming large amounts of sugar alcohols can lead to gastrointestinal issues such as bloating, gas, and diarrhea. Therefore, the statement that sugar alcohols are completely absorbed by the body is false.

Sorbitol and xylitol are both alcohols that can be found in sugar-free candy. Sorbitol is a sugar alcohol commonly used as a sweetener in sugar-free products, including candy. Xylitol is another sugar alcohol that is also used as a sweetener in sugar-free candy. Ethanol, on the other hand, is not typically found in sugar-free candy as it is a different type of alcohol commonly used in alcoholic beverages. Therefore, the correct answer is options 1 and 2, which are sorbitol and xylitol.

Fudge is a type of candy that is known for its smooth and creamy texture. It is made by mixing sugar, butter, and milk, which is then heated and cooled to create a crystalline structure. This process gives fudge its unique texture and appearance. Therefore, the statement "Fudge is a crystalline candy" is true.

Amorphous solids do not have a rigid order in their atomic arrangement. Unlike crystalline solids, which have a regular and repeating pattern, amorphous solids have a disordered atomic structure. This lack of long-range order gives them unique properties such as isotropy and the absence of a definite melting point. Therefore, the statement that amorphous solids are arranged in a rigid order is false.

The correct answer is corn syrup, sucrose, polyvinyl acetate. These ingredients are commonly found in chewing gum. Corn syrup and sucrose are sweeteners that provide the gum with its sugary taste. Polyvinyl acetate is a type of synthetic polymer that gives the gum its chewy texture.

Rock candy is not cooled quickly to prevent large crystals from forming. In fact, the opposite is true. Rock candy is made by slowly cooling a supersaturated sugar solution, allowing the sugar molecules to come together and form large, well-defined crystals. This slow cooling process is essential for the formation of the characteristic rock candy structure.

Amorphous solids do not have a definite crystalline structure and are often transparent or translucent. This makes them suitable for creating breakable movie props that need to shatter realistically on screen. Crystalline solids have a regular repeating pattern, making them less suitable for creating breakable props. Type of rock candy and elastomers are not typically used for making breakable movie props.

Polyvinyl acetate is an example of a resin. Resins are a type of solid or semi-solid organic substance that are typically transparent or translucent and have a brittle or sticky consistency. Polyvinyl acetate is a synthetic resin that is commonly used in adhesives, paints, and coatings due to its strong bonding properties. It is also used in the production of various consumer products such as wood glue, paper coatings, and textile finishes.
