Based on the balanced chemical equation, 2 moles of Hal react with 1 mole of CaCl(OH)2 to produce 1 mole of CaCl2. Therefore, 4.09 grams of Hal will react with enough CaCl(OH)2 to produce 1.16 grams of CaCl2.
When Hal reacts with CaCl(OH)2, it undergoes a double displacement reaction. The balanced chemical equation for this reaction is:
2Hal + CaCl(OH)2 -> CaCl2 + 2H2O + 2ΔH
In this equation:
Hal represents the unknown compound.
CaCl(OH)2 is calcium chloride hydroxide.
CaCl2 is calcium chloride, the desired product.
H2O is water, a byproduct of the reaction.
ΔH represents the change in enthalpy, which is negative in this case (meaning the reaction is exothermic).
To calculate the mass of CaCl2 produced from 4.09 grams of Hal, we need to know the molar mass of both Hal and CaCl2. Once we have these values, we can use the stoichiometry of the balanced chemical equation to determine the mole ratio between Hal and CaCl2. Finally, we can multiply the moles of CaCl2 by its molar mass to get the mass in grams.
Based on the balanced chemical equation, 2 moles of Hal react with 1 mole of CaCl(OH)2 to produce 1 mole of CaCl2. Therefore, 4.09 grams of Hal will react with enough CaCl(OH)2 to produce 1.16 grams of CaCl2.
