90 nitroglycerin (c3h5n3o9) is a powerful explosive. its decomposition may be represented by this reaction generates a large amount of heat and many gaseous products.

Consider the gold isotope 197Au. How many electrons, protons, and neutrons are in a neutral 197Au atom?

When 1.010 of sucrose (C12H22O11) undergoes combustions in a bomb calorimeter, the temperature rises from 24.92 ◦ C to 28.33 ◦ C. Find DErxn for the combustion of sucrose in kJ/mol sucrose.

Propane can be turned into hydrogen by the two-step reforming process. In the first step, propane and water react to form carbon monoxide and hydrogen: C3H8 (g) + 3H2O (g) →3CO (g) + 7H2 (g) In the second step, carbon monoxide and water react to
