Plz Help Consider the balanced chemical reaction below and determine the percent yield for sodium bromide if 3.87 moles of iron III bromide yielded 10.4 moles of sodium bromide.

2FeBr3 + 3Na2S -> Fe2S3 + 6NaBr

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
