what mass of Cl2 is produced from the reaction of 665 g of Hal
In my 75 yrs if working with chemistry I've never run across Hal.
To determine the mass of Cl2 produced from the reaction, we need to know the balanced chemical equation for the reaction between Hal and Cl2. Without that information, it is not possible to provide an accurate answer.
However, I can guide you on how to find the answer yourself once you have the balanced chemical equation. Here's a step-by-step process to solve the problem:
1. Write the balanced chemical equation for the reaction between Hal and Cl2.
2. Identify the stoichiometry of the reaction, which is the mole ratio between Hal and Cl2. This ratio is determined by the coefficients in the balanced chemical equation. For example, if the equation is:
Hal + x Cl2 → y Cl2
The stoichiometry is x moles of Hal to y moles of Cl2.
3. Convert the given mass of Hal (665 g) to moles. To do this, divide the mass by the molar mass of Hal, which can be found on the periodic table.
4. Use the stoichiometry from step 2 to determine the moles of Cl2 produced. Multiply the moles of Hal by the mole ratio of Cl2 to Hal.
5. Convert the moles of Cl2 to mass. Multiply the moles of Cl2 by the molar mass of Cl2.
Following these steps should help you calculate the mass of Cl2 produced once you have the balanced chemical equation for the reaction.
