The amount of Iron (Fe) produced is approximately 6.19 grams.
Explicación
## Step 1The balanced chemical equation for the reaction is given as:###
This equation tells us that 2 moles of Aluminum (Al) react with 3 moles of Iron(II) oxide (FeO) to produce 1 mole of Aluminum oxide (Al2O3) and 3 moles of Iron (Fe).## Step 2The molar mass of Aluminum (Al) is approximately 26.98 g/mol, and the molar mass of Iron(II) oxide (FeO) is approximately 71.85 g/mol.## Step 3We are given that 3.0 grams of Aluminum (Al) and 3.0 grams of Iron(II) oxide (FeO) are used in the reaction. We need to convert these amounts into moles using the formula:###
## Step 4Using the above formula, we find that 3.0 grams of Aluminum (Al) is approximately 0.111 moles, and 3.0 grams of Iron(II) oxide (FeO) is approximately 0.042 moles.## Step 5According to the balanced chemical equation, 2 moles of Aluminum (Al) react with 3 moles of Iron(II) oxide (FeO). Therefore, the ratio of Aluminum (Al) to Iron(II) oxide (FeO) is 2:3.## Step 6We can use this ratio to find out how much Iron (Fe) will be produced. The ratio of Aluminum (Al) to Iron (Fe) is 2:3, so the amount of Iron (Fe) produced will be
times the amount of Aluminum (Al) used.## Step 7Using the above ratio, we find that approximately 0.111 moles of Aluminum (Al) will produce approximately 0.111 moles of Iron (Fe).## Step 8The molar mass of Iron (Fe) is approximately 55.85 g/mol. Therefore, 0.111 moles of Iron (Fe) will weigh approximately 0.111 moles * 55.85 g/mol = 6.19 grams.
