🤓 Based on our data, we think this question is relevant for Professor Gurira's class at University of Wisconsin - Platteville.

FREE Expert Solution

The percent yield of a reaction is given by:

We first need to calculate the theoretical yield of the reaction, using the given amount of reactant. The actual yield is given as 128 g.

Balanced Equation: The given reaction is:

PCl3 + H2O → HCl + H3PO3

We first need to balance this chemical equation. Add a coefficient of 3 to HCl to balance the number of Cl:

PCl3 + H2O → 3 HCl + H3PO3

Add a coefficient of 3 to H2O to balance the number of O. The balanced complete equation is::

PCl3 + 3 H2O → 3 HCl + H3PO3
