How Dangerous is Hydrofluoric Acid? Though hydrofluoric acid is considered a weak acid, it is one of the most dangerous inorganic acids. Burns of as little as 1% body surface area, or about 25 sq in, have been known to be fatal due to the acid’s unique properties. Hydrofluoric acid pen...
The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible lig...

Repellants are used to repel insects. Repellants, rather than killing insects, repel them. Repellants are relatively mild as compared to insecticides, hence suitable for application on human skins. Insecticides are considered dangerous, and some of them are banned for home use too. ...
“We would love to see global understanding on things like which hazardous substances should not be used,” Steinberger says. “If a substance is dangerous, it’s dangerous in any country. The electronics industry is not a clean industry. We are using lots of chemicals, and I think it’...
aNext I'll invent many high-tech in the future, to sustain our world better. I want to study flying cars, allowing people to easily cars, driving in the sky. But, the kind of car, no-emission, when confronted with a dangerous or may drive, so that people avoid the danger. I want...
