Calculate the percent yield for the reaction: P4 (s) + 6 Cl2 (g) → 4 PCl3 (l) if 75.0 g of phosphorus reacts with excess chlorine gas to produce 111.0 g of phosphorus trichloride.

How many grams of C2H2 are needed to react according to the equation to release 2570jk of heat?

A piece of metal, weighing 59.047, was heated to 100.0 degrees C. The metal was paced into a coffee cup calorimeter containing 100.0mL of water (initially at 23.7 degree C). the metal and water were allowed to come to an equilibrium temp, determined to be 27.8 degree C. Assuming no heat was lost to the surroundings, calculate the specific heat of the metal.

1)calculate the hat absorbed by the water

2)calculate the specific heat of the metal

A confined quantity of gas is at a pressure of 2.50 atm and a temperature of -10°C, what is the pressure if the temperature is increased to 22°C

Formic acid, HCHO2, burns in oxygen to form carbon dioxide and water as follows: HCHO2 (aq) + O2 (g) → 2 CO2 (g) + 2 H2O (l). If a 3.15-g sample of formic acid was burned in 2.0 L of oxygen, what volume of carbon dioxide would be produced? (Assume the reaction occurs at standard temperature and pressure, STP.
