A student carries out the following reaction: 2 Fe (s) + 3 S (g) → Fe2S3 (s). The student determines that 2.67 moles of iron (III) sulfide were produced, resulting in a percent yield of 63%. Prior to conducting the reaction of iron with sulfur, the student produced the gaseous sulfur that was used via heating solid sulfur in a syringe.

S8 (s) + heat → 8 S (g)

Assume all of the sulfur was converted to the gaseous form, and the entirety of the gaseous sulfur was used in the reaction. What mass of solid sulfur was used in producing the gaseous sulfur?

A.
408 g

B.
913 g

C.
484 g

D.
8547 g

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
