The melting point of sodium bromide a salt is 755c Calculate this temperature in and in f kelvins?
The melting point of sodium bromide (a salt) is 755 . Calculate this temperature in and in kelvins.
What is the melting point of sodium bromide?
Bromine (Br): Melting point: - 7,2 0C Boiling point: + 58,8 0C
What is the Chemical formula for sodium bromide gas?
NaBr is sodium bromide but it is an ionic solid with a high melting point and extremely unlikely to be a gas.
Why is benzene formed during Grignard reactions using phenylmagnesium bromide?
Grignard reactions must be carried out in an anhydrous environment in an anhydrous solvent (e.g. anhydrous ether). Why? Grignard reagents behave essentially as a carbanion, and are extremely reactive. Therefore they cannot be carried out while acidic hydrogens, or other positive reactive centers are present (carbonyl compounds such as acetone) in the reaction mixture because there is no way to stop the Grignard from reacting with these other compounds rather than the desired reactant. If phenylmagnesium bromide were prepared, and ANY water was present in the reaction mixture phenylmagnesium bromide would not hesitate to react with water--stealing one of its hydrogens. This hydrogen would therefore replace the attached --MgBr to form benzene.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.

Which of following solids would hae higher melting point AlO3 vs NaBr?
Aluminum oxide (Al2O3) would have a higher melting point than sodium bromide (NaBr). This is because aluminum and oxygen ions in Al2O3 are more strongly bonded through covalent bonds, while sodium and bromide ions in NaBr are held together by weaker ionic bonds. Stronger bonding requires more energy to break, resulting in a higher melting point.
