Consider the balanced chemical reaction when phosphorus and iodine react to produce phosphorus triodide:

2 P(s) + 3 I2(g) → 2 PI3(g)

If 131 g of I2(s) are reacted with excess P(s) to produce 0.306 mol of PI3(g), what is the percent yield of PI3(g)?

When the ionic compound nabr dissolves in water, br– ions are pulled into solution by the attraction between what two particles? a. the na+ and br– ions b. the na+ ion and the negative end of a water molecule c. the br– ion and the positive end of a water molecule d. the br– ion and the negative end of a water molecule
