A fundamental non-metal element that plays a crucial role in organic chemistry and forms the basis of a vast array of organic compounds, while also existing in various natural forms such as diamond, graphite, and amorphous carbon.
An essential building block of life, present in significant quantities in living organisms, and integral to the structure of many biological molecules and materials.
A chemical element characterized by its presence in nature as a component of carbonates and carbon dioxide, contributing to both geological and atmospheric processes.
A versatile element known for its stability and ability to form multiple allotropes, each with distinct physical properties, widely utilized in industrial applications including steel production and as a reducing agent.
Example:
石炭は大部分が炭素から成っている。
A colorless and odorless gas that is produced when fuels like charcoal burn incompletely; it is highly toxic and can accumulate in enclosed spaces, leading to poisoning.
A chemical compound with the formula CO, known for its ability to bind with hemoglobin in the blood, which impairs the blood’s capacity to carry oxygen, making it a dangerous substance.
A byproduct of combustion processes, especially in poorly ventilated areas, where it poses a significant health risk due to its role as a silent killer that can lead to unconsciousness or death without warning.
Utilized in various industrial processes, including the production of methanol and formalin, this gas is recognized for its properties as a reducing agent in chemical reactions.
Example:
一酸化炭素とは炭素化合物の不完全燃焼で発生する有害物質です。
A lightweight and strong textile material made by carbonizing specific precursors, such as polyacrylonitrile fibers or coal tar pitch fibers, at high temperatures in a nitrogen environment, resulting in enhanced strength and elasticity compared to metals.
A specialized type of fiber that exhibits exceptional heat resistance and chemical durability, commonly utilized in the manufacturing of components for aerospace and automotive industries due to its advantageous properties.
A compound formed by the combination of carbon and oxygen, often produced during combustion processes and present in the atmosphere as a minor component.
A colorless, odorless gas that is a byproduct of burning fossil fuels and organic matter, known for its role in the greenhouse effect and climate change.
A chemical substance that consists of one carbon atom bonded to two oxygen atoms, commonly released in processes such as respiration and fire.
A medical condition resulting from the inhalation of a large amount of carbon monoxide, which binds to iron-containing substances in the body, like hemoglobin, disrupting their normal function and impairing cellular respiration.
A dangerous and potentially fatal health issue characterized by symptoms such as headache, dizziness, and nausea, arising from exposure to elevated levels of carbon monoxide, particularly when concentrations reach 10 parts per million or more.
A type of poisoning that can lead to severe neurological impairments or death, particularly at high concentrations, due to the prevention of oxygen transport in the bloodstream and the subsequent impact on vital bodily functions.
