To determine the ratio of moles in a chemical reaction, you can use the coefficients of the balanced chemical equation. The coefficients represent the number of moles of each substance involved in the reaction. By comparing the coefficients of the reactants and products, you can determine the mole ratio between them.

The rusting of iron has the reaction 4 Fe + 3 O2 equals 2 Fe2O3. So every 2 moles of iron produces 1 moles of iron oxide. 16.7 grams is .299 moles of iron. This means there are 0.149 moles of iron oxide or 23.88 grams.
To determine the empirical formula from moles in a chemical compound, you first need to find the moles of each element present in the compound. Then, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.
To find the excess reagent, first write and balance the chemical equation for the thermite reaction: 2Al + Fe2O3 -> 2Fe + Al2O3 Next, determine the limiting reagent using the mole ratios (in this case, Fe2O3 is limiting). Then, calculate the moles of excess reagent left over (Al) using the mole ratio from the balanced equation. Subtract the moles of Al consumed from the initial moles of Al to find the excess.
The first step is to convert the masses of Fe and O into moles: 174.86 g Fe is 3.13 moles of Fe, and 75.14 g O is 4.69 moles of O. The ratio of Fe to O in the compound is approximately 2:3. Therefore, the empirical formula of the compound is Fe2O3, which is iron(III) oxide (also known as rust).
To determine the mass of Fe2O3 formed, you need to first find the molar mass of Fe and Fe2O3. Then, use stoichiometry to calculate the mass of Fe2O3 that can be produced from 16.7 g of Fe. The balanced equation is 4Fe + 3O2 → 2Fe2O3, which shows that 4 mol of Fe produces 2 mol of Fe2O3. By converting 16.7 g of Fe to moles, you can then use the mole ratio to find the grams of Fe2O3 formed.
