How do you know which equation (law) to use when plugging in the numbers?

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

i believe it is c.) 1575 j.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
