Answer:
The balanced chemical equation for the reaction between BaCl2 and Na2SO4 is:
BaCl2 + Na2SO4 → 2 NaCl + BaSO4
This equation shows that one mole of BaCl2 reacts with one mole of Na2SO4 to produce two moles of NaCl and one mole of BaSO4. Therefore, to determine how many moles of NaCl can be produced from 2.5 moles of BaCl2, we need to use the stoichiometry of the reaction.
Steps:
Step 1: Write down the balanced chemical equation for the reaction between BaCl2 and Na2SO4.
BaCl2 + Na2SO4 → 2 NaCl + BaSO4
Step 2: Identify the stoichiometric ratio of BaCl2 to NaCl from the balanced chemical equation.
From the balanced chemical equation, we see that 1 mole of BaCl2 produces 2 moles of NaCl.
Step 3: Calculate the number of moles of NaCl produced from 2.5 moles of BaCl2.
Using the stoichiometric ratio, we can calculate the number of moles of NaCl produced from 2.5 moles of BaCl2 as follows:
2.5 moles BaCl2 x (2 moles NaCl / 1 mole BaCl2) = 5 moles NaCl
Therefore, 2.5 moles of BaCl2 can produce 5 moles of NaCl.
