When coal is burned to produce electricity, the electrical energy produced is less than the potential energy of the coal. Which best explains this
observation?
as the coal is heated, the molecules move so fast that they are destroyed
some of the energy in the coal is destroyed by the intense heat required to release its
potential energy
some of the potential energy in the coal is converted into forms of energy other than
electricity
the amount of energy in the coal is not known

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
