Calculate the amount of heat energy, in units of kilojoules, required to melt 75.0 g of ice at 0.0°C. (molar heat of fusion of ice = 6.01 × 10^3 J/mol)

What phase transition is occurring between points B and C on the heating curve?

As plaque biofilm matures, it becomes more pathogenic. Some local factors can allow plaque biofilm to mature and increase in pathogenicity.

Also known as “T-stoff”, this oxidizer was widely used in Germany during WW2. It was used to power the Me-163A “Komet”.

The elements that provide the best oxidizer performance are Nitrogen and Carbon.
