Question

Which of the following minerals are used for the packaging of food items and minerals?
A. Aluminum
B. Chromium
C. Copper
D. Manganese

Answer 1

Minerals are solid substances that are present in nature and can be made of one element or more elements combined together.
It is a silvery-white, lightweight metal.
It is soft and malleable.

Complete answer: Chromium: Chromium is used to harden steel, to manufacture stainless steel, and to produce several alloys.
Chromium plating can be used to give a polished mirror finish to steel.
Copper: Most copper is used in electrical equipment such as wiring and motors.
This is because it conducts both heat and electricity very well, and can be drawn into wires.
It also has uses in construction (for example roofing and plumbing), and industrial machinery.
Manganese: Manganese is a mineral that is found in several foods including nuts, legumes, seeds, tea, whole grains, and leafy green vegetables.
It is considered an essential nutrient because the body requires it to function properly.
Manganese (IV) oxide is used as a catalyst, a rubber additive, and to decolorize glass that is colored green by iron impurities.
Manganese sulfate is used to make a fungicide.
Manganese (II) oxide is a powerful oxidizing agent and is used in quantitative analysis.
Aluminum: Aluminum is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs, and airplane parts.
Commonly used to make cans, foil, and laminated paper or plastic packaging, aluminum is a lightweight, silvery-white metal derived from bauxite ore, where it exists in combination with oxygen as alumina.

So, the answer is A. Aluminum

Note: Aluminum is highly resistant to most forms of corrosion.
It’s a natural coating of aluminum oxide that provides a highly effective barrier to the effects of air, temperature, moisture, and chemical attack.
