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.
Answer:
First, place no. 5 in front of the CO2 in order to balance the carbon atoms. Next, place no. 6 in front of H2O to balance the hydrogen atoms. Lastly place no. 8 in front of the O2 so that there are 16 oxygen atoms on both sides of the reaction.
Chemical bonds have been broken down and new substances have been formed. Hope this helps.
I do not know the specific "statement" that illustrates the difference between a chemical reaction and a nuclear reaction but i can explain it my way: A nuclear reaction is relitively larger than a chemical reaction. A nuclear reaction can cause far more and more severe damage than as a chemical can.
<span>There are a number of ways
to express concentration of a solution. This includes molality. Molality is
expressed as the number of moles of solute per mass of the solvent. We calculate as follows:
0.200 mol I2 / kg CCl4 ( .750 kg CCl4 ) ( 253.809 g I2 / mol I2) = 38.07 g I2 needed
Hope this helps.
