Answer:
The mole ratio of BaCl2 to NaOH can be determined by looking at the balanced chemical equation for the reaction between these two compounds.
Step-by-step explanation:
In the balanced equation, the coefficients in front of each compound represent the number of moles of each substance involved in the reaction. The mole ratio is determined by comparing these coefficients.
The balanced chemical equation for the reaction between BaCl2 and NaOH is:
BaCl2 + 2NaOH -> Ba(OH)2 + 2NaCl
From the equation, we can see that for every 1 mole of BaCl2, 2 moles of NaOH are required. This means that the mole ratio of BaCl2 to NaOH is 1:2.
To illustrate this, let's consider an example. If we have 2 moles of BaCl2, we would need 4 moles of NaOH to react completely according to the balanced equation.
It is important to note that the mole ratio is based on the coefficients in the balanced chemical equation and represents the stoichiometry of the reaction. It provides information about the relative number of moles of each substance involved in the reaction.
