Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction: Fe O2 → Fe2O3 This equation is unbalanced. Which of the following is the correct balanced equation for this reaction? A. 4Fe 3O2 → 2Fe2O3 B. 3Fe 4O2 → 2Fe2O3 C. 2Fe 4O2 → 3Fe2O3 D. 3Fe 3O2 → 4Fe2O3 E. 4Fe 4O2 → 3Fe2O3.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

it is b that is the answer.
