What is hydrogen bonding and how might hydrogen bonding be used to explain the substantial difference in boiling between ethanol CH3CH2OH (grain alcohol) and dimethyl ether (CH3OCH3)? What are the properties of water such as type of bonding and boiling point? What effect does polarity ...
What is graphene hydroxide used for? What is the chemical formula for milk? What is the chemical formula for the hydrogen carbonate ion? What is the chemical name for water? What is the name of the compound with the formula (NH4) 2 SO4 ?
A PCB acid trap, also sometimes referred to as an acid scrubber, is a device used to neutralize acidic contaminants from gas streams in industrial processes and environments. PCB stands for printed circuit board. PCB manufacturingutilizes many harsh chemicals and produces waste byproducts that can ...
HYDROQUINIDINE is commonly used as an organic small molecule catalyst in organic synthesis research. These catalysts can be used to promote asymmetric chiral synthesis reactions and generate chiral organic compounds. This is important for the preparation of molecules with specific spatial structures, as c...
2-Methylimidazole is used as a raw material, a chemical intermediate, and as a component in the manufacture of pharmaceuticals, photographic and photothermographic chemicals, dyes and pigments, agricultural chemicals and rubber. It is also widely used as a polymerization cross-linking accelerator and ...
and introducing hydrogen bromide at 0.6-0.8 MPa, Phosphorus tribromide ester is synthesized at 115-120°C; then methanol is added for deesterification to synthesize 3. Although this method can improve the purity, a large amount of hydrogen bromide is required in the deesterification process, which...
Hydrogen ion concentration is the basis for the pH value of the solution. $$\rm pH = -\log{\;[H^+]}$$ Answer and Explanation: First, we need to solve for {eq}K_a{/eq}: {eq}K_a = \dfrac{K_w}{K_b}\\ K_a = \dfrac{1.0\times10^{-14}}{4.4...

NPB or also known as N-Propyl bromide or 1-bromopropane, is a solvent that is used in metal cleaning, vapor degreasing, and dry cleaning.
flame retardant. However, this kind of copper clad laminate containing bromine will release a large amount of toxic gas (brominated type) during combustion or electrical fire. When PCB is used for hot air leveling and component welding, the board will also release a small amount of hydrogen br...
