4FeCr2O4+ 8K2CO3+7O2= 2Fe2O3+8K2CrO4+8CO2

how many grams of FeCr2O3 are required to produce 44g of CO2?

44 g of CO2 is two moles, right?

We use the coefficents to make a mole ratio

2/8=x/4
so x is the moles of Iron(II) dichromate
So figure how many grams is x.

To determine the number of grams of FeCr2O3 required to produce 44g of CO2, we need to use stoichiometry, which is the ratio of the coefficients in the balanced chemical equation.

Looking at the balanced equation:

4FeCr2O4 + 8K2CO3 + 7O2 → 2Fe2O3 + 8K2CrO4 + 8CO2

We can see that the coefficient of Fe2O3 is 2, and the coefficient of CO2 is 8.

Using a ratio, we can calculate the number of moles of FeCr2O3 required to produce 1 mole of CO2:

2 moles of FeCr2O3 → 8 moles of CO2

Now, we can convert the given mass of CO2 (44g) into moles:

44g CO2 * (1 mole CO2 / 44g CO2) = 1 mole CO2

Using the stoichiometric ratio, we can determine the moles of FeCr2O3:

1 mole CO2 * (2 moles FeCr2O3 / 8 moles CO2) = 0.25 moles FeCr2O3

Finally, we can convert moles of FeCr2O3 into grams:

0.25 moles FeCr2O3 * (203.8 g FeCr2O3 / 1 mole FeCr2O3) = 50.95 g FeCr2O3

Therefore, approximately 50.95 grams of FeCr2O3 are required to produce 44 grams of CO2.

To find the number of grams of FeCr2O3 required to produce 44g of CO2, we need to use the given balanced chemical equation and the concept of stoichiometry.

The balanced chemical equation is:
4FeCr2O4 + 8K2CO3 + 7O2 → 2Fe2O3 + 8K2CrO4 + 8CO2

From the balanced equation, we can determine the stoichiometric ratio between FeCr2O4 and CO2. According to the equation, 4 moles of FeCr2O4 react to produce 8 moles of CO2.

Now, let's calculate the molar mass of CO2:
C: 1 atom x 12.01 g/mol = 12.01 g/mol
O: 2 atoms x 16.00 g/mol = 32.00 g/mol
Total molar mass of CO2 = 12.01 g/mol + 32.00 g/mol = 44.01 g/mol

Next, we can use the stoichiometric ratio to determine the number of moles of CO2 produced when 44 g of CO2 is formed:
Moles of CO2 = Mass of CO2 / Molar mass of CO2
Moles of CO2 = 44 g / 44.01 g/mol ≈ 1 mole

Since the stoichiometric ratio between FeCr2O4 and CO2 is 4:8, the number of moles of FeCr2O4 required will be half of the number of moles of CO2:
Moles of FeCr2O4 = 1 mole / 8 = 0.125 moles

Now, let's calculate the molar mass of FeCr2O4:
Fe: 2 atoms x 55.85 g/mol = 111.70 g/mol
Cr: 2 atoms x 51.99 g/mol = 103.98 g/mol
O: 4 atoms x 16.00 g/mol = 64.00 g/mol
Total molar mass of FeCr2O4 = 111.70 g/mol + 103.98 g/mol + 64.00 g/mol = 279.68 g/mol

Finally, we can calculate the mass of FeCr2O4 required to produce 44 g of CO2:
Mass of FeCr2O4 = Moles of FeCr2O4 x Molar mass of FeCr2O4
Mass of FeCr2O4 = 0.125 moles x 279.68 g/mol ≈ 34.96 g

Therefore, approximately 34.96 grams of FeCr2O4 are required to produce 44 grams of CO2.

1. Check your equation. I think you've made a typo. Fe2CrO4?? FeCrO4 perhaps? Then make sure the equation is balanced.

2. Convert 44 g CO2 to moles. moles = grams/molar mass.

3. Using the coefficients in the balanced equation, convert moles CO2 to moles of what you want.

4. Now convert moles from 3 to grams.
grams = moles x molar mass.
