An iron bar has a mass of 771 g. after the bar had been standing in air for a month, exactly one-eighth of the iron turned to rust (fe2o3). calculate the final mass of the iron bar and the rust.

explain your calculations; i want to understand how to find the answer

N2(g) + 3H2(g) → 2NH3(g)

Balanced chemical equations only show formulae, not names. A balancing number, written in normal script, multiplies all the atoms in the substance next to it.

let that person have a turn to speak : )

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
