Although coal is a complex mixture of substances, its elemental composition can be approximated by the formula C135H96O9NS. Using this formula, predict the amount of CO2 released from the combustion of 1.00 × 106 metric tons of coal (about the annual average for a coal-fired power plant). 1 metric ton = 1 ×103 kg.

What does a particular point on a line of a phase diagram represent? o a. the maximum temperature a substance can exist at without bonds breaking b. the pressure created by the kinetic energy of molecules at a particular temperature c. the melting point or boiling point of a substance at a specific pressure d. the conditions in which temperature and pressure have equal effects on a substance

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder

Describe what happens to the molecules as water goes from ice to liquid to vapor. be sure to explain what happens to the temperature during the phase changes.
