One of the reactions for rusting iron is as follows: 4fe + 3o2 → 2fe2o3 (mm fe: 55.85 g/mol; mm o2=32 g/mol; mm fe2o3=159.70 g/mol) if 63.98 g of oxygen gas is completely consumed, how many moles of iron (iii) oxide are formed? a. 1.333 mol b. 3071 mol c. 2.999 mol d. 6812 mol

A. 1.333 mol

Explanation:

To calculate the moles, we use the equation:

As oxygen is completely consumed, it is the limiting reagent and will limit the formation of .

According to stochiometry,

3 mole of produces 2 moles of

Thus 2 moles of will produce= moles of

Thus the correct answer is 1.333 moles

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
