What is the longest chemical reaction?
As to the uncatalyzed phosphate monoester reaction of 1 trillion years, “This number puts us way beyond the known universe in terms of slowness,” he said. “(The enzyme reaction) is 21 orders of magnitude faster than the uncatalyzed case.
What is the chemical formula of the compound?
The chemical formula of a compound is a symbolic representation of its chemical composition. Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules.
What is the hardest chemical compound?
With a Mohs hardness between 9 and 10, boron carbide is one of the hardest synthetic substances known, being exceeded only by cubic boron nitride and diamond.
What molecule is the largest?
PG5
MEET PG5, the largest stable synthetic molecule ever made. With a diameter of 10 nanometres and a mass equal to 200 million hydrogen atoms, this tree-like “macromolecule” paves the way for sophisticated structures capable of storing drugs within their folds, or bonding to a wide variety of different substances.
What is the longest chemical element?
The prize for the longest element name goes to rutherfordium, named after the famous New Zealand physicist Lord Ernest Rutherford who won a Nobel Prize in chemistry. Praseodymium means ‘green twin’, a name that relates to confusion over the supposed element didymium.
What’s the longest chemical name?
isoleucine
isoleucine (189,819 letters) If we’re talking chemistry, the longest chemical name is 189,819 letters long. It is the chemical name for titin, a giant filamentous protein essential to the structure, development, and elasticity of muscle.
Is O2 a compound?
The oxygen molecule O2 is considered a molecule but not a compound. This is because O2 is made of two atoms…
What’s tougher than a diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
How do you find the largest molecule?
Hint: To find out which molecule will have the largest number of molecules, first try to calculate the number of moles of each compound given. The compound having the largest number of mole values will have the largest number of molecules.
What is the largest hydrocarbon?
Earlier this year, the University of Michigan chemist published a paper with coworker Zhifu Xu announcing the synthesis and characterization of the largest all-hydrocarbon molecule ever made—C 1134 H 1146 [ Angew.
