Understanding the Chemical Reaction
Chemical reactions involve the transformation of one or more substances into new substances. In this article, we will focus on a specific reaction involving manganese, iodine, and fluorine. The reaction is given as:
This reaction involves the formation of manganese fluoride (MnF3) and iodine pentafluoride (IF5) from manganese iodide (MnI2) and fluorine gas (F2).
Balancing the Chemical Equation
To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides. Let's start by counting the number of atoms of each element:
Reactants:
- Mn: 2
- I: 4
- F: 26
Products:
- Mn: 2
- F: 15
- I: 5
To balance the equation, we need to adjust the coefficients of the reactants and products. Let's start by balancing the manganese atoms. Since there are 2 manganese atoms on both sides, we can leave the coefficient of MnI2 as 2.
Next, let's balance the iodine atoms. There are 4 iodine atoms on the reactant side and 5 iodine atoms on the product side. To balance the iodine atoms, we need to adjust the coefficient of MnI2. Let's multiply the coefficient of MnI2 by 5/4, which gives us:
However, this is not the correct balanced equation. Let's try again. We can start by balancing the fluorine atoms. There are 26 fluorine atoms on the reactant side and 15 fluorine atoms on the product side. To balance the fluorine atoms, we need to adjust the coefficient of F2. Let's multiply the coefficient of F2 by 15/13, which gives us:
This is the correct balanced equation.
Understanding Stoichiometry
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. In this article, we will focus on the stoichiometric relationships between manganese fluoride (MnF3) and iodine pentafluoride (IF5).
Calculating the Number of Moles of IF5
The balanced chemical equation is:
We are given that 9.73 moles ofF3 are produced. We need to calculate the number of moles of IF5 that are expected to be produced.
To do this, we can use the mole ratio between MnF3 and IF5. From the balanced equation, we can see that 2 moles of MnF3 are produced for every 4 moles of IF5. Therefore, the mole ratio between MnF3 and IF5 is:
MnF3 : IF5 = 2 : 4
We can simplify this ratio by dividing both numbers by 2, which gives us:
MnF3 : IF5 = 1 : 2
This means that for every 1 mole of MnF3, 2 moles of IF5 are produced.
We are given that 9.73 moles of MnF3 are produced. To calculate the number of moles of IF5 that are expected to be produced, we can multiply the number of moles of MnF3 by the mole ratio:
moles of IF5 = moles of MnF3 x (2/1) = 9.73 x 2 = 19.46
Therefore, we expect 19.46 moles of IF5 to be produced when 9.73 moles of MnF3 are also produced.
Conclusion
