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).
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.
What is the molecular geometry of urea and how does it affect its chemical properties?
The molecular geometry of urea is planar. This flat shape allows urea to form hydrogen bonds easily, making it a good hydrogen bond donor and acceptor. This property affects its solubility in water and its ability to interact with other molecules, influencing its chemical properties such as its reactivity and ability to form complexes with other compounds.
Is dissolution of urea in water endothermic?
Yes. I mean you don't urinate any solids, do you? You may need to heat the water to dissolve urea at a high concentration. The dissolution of urea in water is endothermic (the hot water will cool as urea dissolves!)
What is mixture of urea and water called?
Oh, dude, that's an easy one. A mixture of urea and water is called a solution. It's like when you mix sugar in your coffee - it's all dissolved and blended together. So yeah, it's just a fancy way of saying urea and water hanging out together.
What solid dissolves best in water are twenty degrees Celsius salt sugar iodine chalk or urea?
Sucrose is the most soluble.

Why is urea the best fertilizer?
the urea is better because it has an affordable price for farmers, it has 48% nitrogen if I am not mistaken. also as fertilizer, has high solubility.
Can urea neutralise pH water?
Urea water solution is neutral.
What are the bond angles of urea?
Urea is sp2 hybridized, so the bond angles are ~120 degrees.

What is composed of urea and water that is removed from the blood by the kidneys?
Really? Urea and water... Urine

What temperature does urea change to amonia?
there is a ideal pressure too. Temperature is 150 Celsius units.
What is remedy for urea?
urea is mixed with sterile water and is a remedy for adenocarcinoma cancer
