4Fe + 3O2 → 2Fe2O3
topjm [15]

Answer:

moles Fe₂O₃ = 0.938 mole

Explanation:

Convert given data to moles, solve in terms of moles by reaction ratios in balanced equation. After obtaining answer in moles, convert to needed dimension. In this case, no conversions are needed.

       4Fe              + 3O₂       =>          2Fe₂O₃

105g/56g·mol⁻¹

= 1.875 mol Fe => => => => => =>     2/4(1.875 mol Fe₂O₃) = 0.938 mol Fe₂O₃

How does heat differ from temperature
Sholpan [36]
<span>Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. Heat energy depends on the speed of the particles, the number of particles (the size or mass), and the type of particles in an object.</span>
