What else can I help you with?
Which of the following will have lowest freezing point 1)urea 2)table salt?
Urea, with a melting point of 133-135 0C.
What happens to the melting point of urea and cinnamic acid when mixed?
The melting point will be reduced because an impure substance is not held together as strongly as a pure substance therefore it takes less energy to break the bonds or attractive forces holding the impure substance together.
Why does urea and aspirin have higher melting points than napthalene and pi-dicholorbenzene?
Because urea and aspirin overall are polar compounds, and their intermolecular forces are stronger than napthalene or dichlorobenzene. This means it takes more kinetic energy (heat) to separate their molecules, which translates as a higher melting and boiling points.
Is carpet urea same as nitrogen urea?
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde
What produces a chemical called urea which end up in urine?
The kidneys remove urea from the blood and excrete it in urine. Urea is a waste product formed from the breakdown of proteins in the liver.
Which of the following will have lowest freezing point 1)urea 2)table salt?
Urea, with a melting point of 133-135 0C.
What happens to the melting point of urea and cinnamic acid when mixed?
The melting point will be reduced because an impure substance is not held together as strongly as a pure substance therefore it takes less energy to break the bonds or attractive forces holding the impure substance together.
Which has a greater boiling point urea or glucose and why?
Urea has a higher boiling point than glucose because urea is a larger molecule with stronger intermolecular forces due to its ability to form hydrogen bonds. Glucose, on the other hand, is a smaller molecule that lacks hydrogen bonding sites, resulting in weaker intermolecular forces. This difference in molecular size and bonding interactions leads to urea having a higher boiling point.
What is boiling point of 1 molar urea solution?
The boiling point of a 1 molar urea solution will be higher than the boiling point of pure water. Urea is a non-volatile solute that raises the boiling point of the solution through boiling point elevation. The exact boiling point elevation can be calculated using the formula: ΔTb = i * K_b * m, where i is the van't Hoff factor (1 for urea), K_b is the ebullioscopic constant of the solvent (water), and m is the molality of the solution.
Which has higher boiling point Urea or Sodium chloride?
Sodium chloride (NaCl) has a higher boiling point than urea. This is because sodium chloride forms ionic bonds which are stronger than the hydrogen bonds in urea. Stronger bonds require more energy to break, resulting in a higher boiling point.
Why does urea and aspirin have higher melting points than napthalene and pi-dicholorbenzene?
Because urea and aspirin overall are polar compounds, and their intermolecular forces are stronger than napthalene or dichlorobenzene. This means it takes more kinetic energy (heat) to separate their molecules, which translates as a higher melting and boiling points.
What compound melts at 160 degrees C and is soluble in water?
Sugar (sucrose) crystals will "melt" at 160 degrees C but this is actually oxidation of the molecules, or caramelization. One use of the process is to form invert sugar (sucrose and fructose) that will not recrystallize as easily.
Is carpet urea same as nitrogen urea?
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde
What substance has a melting point of 0 degrees Celsius and a boiling point of 100 degrees Celsius?
Water has a melting point of 0 degrees Celsius and a boiling point of 100 degrees Celsius at standard atmospheric pressure. It is a widely known substance that exists in three states: solid (ice), liquid (water), and gas (water vapor).
How you control urea?
please give me some knowledge about what is urea and how i am save .and urea .in which food
Examples of endothermic reactions in everyday life?
Ice melting: The process of ice melting absorbs heat from the surroundings, causing a decrease in temperature. Baking bread: The process of baking bread requires energy input from the oven to create the endothermic reaction needed for the dough to rise. Photosynthesis: Plants use sunlight energy to convert carbon dioxide and water into glucose and oxygen, which is an endothermic process.
Is urea a carbohydrate?
no, urea is a breakdown of protein
