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 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
