3 days ago · Formaldehyde ( / fɔːrˈmældɪhaɪd / ⓘ for-MAL-di-hide, US also / fər -/ ⓘ fər-) ( systematic name methanal) is an organic compound with the chemical formula CH2O and structure H−CHO, more precisely H2C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde.
Jun 25, 2024 · The melting point is 770 °C (1,418 °F), and the boiling point is 1,420 °C (2,588 °F). Potassium chloride readily dissolves in water, and the aqueous solution that forms is a good conductor of electricity .
Jun 21, 2024 · Pure acetic acid, often called glacial acetic acid, is a corrosive, colourless liquid (boiling point 117.9 °C [244.2 °F]; melting point 16.6 °C [61.9 °F]) that is completely miscible with water. William H. Brown
3 days ago · Methane is easier to store than hydrogen due to its higher boiling point and density, as well as its lack of hydrogen embrittlement. [30] [31] The lower molecular weight of the exhaust also increases the fraction of the heat energy which is in the form of kinetic energy available for propulsion, increasing the specific impulse of the rocket.
4 days ago · For a metal, zinc has relatively low melting (419.5 °C) and boiling point (907 °C). The melting point is the lowest of all the d-block metals aside from mercury and cadmium; for this reason among others, zinc, cadmium, and mercury are often not considered to be transition metals like the rest of the d-block metals.
