convert 114G C5H5Cl to __g DDT (or C14H9Cl5)
convert 485g C2HOCl3 to __g DDT
which one is smaller? that's the limiting reagent! that's how much mass of DDT is formed!
when this maken formula
To determine the mass of DDT formed, we need to first balance the chemical equation for the reaction between chlorobenzene (C6H5Cl) and chloral (C2HOCl3) to produce DDT (C14H9Cl5) and water (H2O):
2C6H5Cl + C2HOCl3 → C14H9Cl5 + H2O
Next, we need to calculate the number of moles of chlorobenzene (C6H5Cl) and chloral (C2HOCl3) using their respective molar masses. The molar mass of chlorobenzene is 112.56 g/mol, and the molar mass of chloral is 147.39 g/mol.
Number of moles of chlorobenzene:
Mass of chlorobenzene / Molar mass of chlorobenzene
= 114 g / 112.56 g/mol
Number of moles of chloral:
Mass of chloral / Molar mass of chloral
= 485 g / 147.39 g/mol
Next, we need to determine the limiting reactant, which is the reactant that will be completely consumed and determine the amount of product formed. It can be determined by comparing the mole ratio between the reactants and the coefficients in the balanced equation.
From the balanced equation, the mole ratio between chlorobenzene and chloral is 2:1.
So, if we have "x" moles of chlorobenzene, we would need 2x moles of chloral to react completely.
By comparing the moles of chlorobenzene and chloral, we can determine that the limiting reactant is chloral. Let's calculate the moles of chloral based on its stoichiometry with chlorobenzene.
Moles of chloral = (2 * Moles of chlorobenzene) / 1
Now, using the moles of chloral, we can determine the moles of DDT formed since the coefficients are 1 for both chloral and DDT.
Moles of DDT = Moles of chloral
Finally, we can calculate the mass of DDT formed using the moles of DDT and its molar mass, which is 354.49 g/mol.
Mass of DDT = Moles of DDT * Molar mass of DDT
By following these steps, you can calculate the mass of DDT formed in the given reaction.
