The answer is 546K. If you need the answer in degrees Celsius you subtract 273 from 546 and get 273 degrees Celsius. I included how I got the answer in the photo below. Hope this helps!
Physical Properties
Sucrose has a monoclinic crystal structure.
When subjected to high temperatures (over 186oC), this compound decomposes, yielding caramel.
Its solubility in water at a temperature of 20oC is 203.9g/100mL.
The standard enthalpy of combustion corresponding to sucrose is 5647 kJ. mol-1.
D. Hypothesis Formation I hope this help ☺
The answer is a. triple beam balance
In excitation electrons move from an energy level to a higher energy level
and ionization is to remove an electron from an atom.
