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

  balanced chemical equations follow the law of conservation of mass and charges. the masses and charges on either sides of the equation should be balanced.in conservation of mass, the number of atoms of each element on left side should be equal to the number of atoms of each element on the right side of the equation.1)k₂so₄ + 2ca(no₃)₂ --> 2kno₃ + 2caso₄number of ions        left side             right side  k⁺         2                         2so₄²⁻   1                         2ca²⁺     2                         2no₃⁻     4                         2in this equation the masses of so₄²⁻ and no₃ are not balanced. therefore this equation violates the law of conservation of mass2)ti + 2 cl₂ > ticl₄        left side       right side  ti           1               1cl           4               4this equation follows the law of conservation of mass3)2c₂h₂ + 5o₂ > 4co₂   + 2h₂o              left side     right side  c               4               4h               4               4o             10             10this equation follows the law of conservation of mass4)baso₄ + 2naoh --> ba(oh)₂   + na₂so₄          left side       right side  ba       1                   1so₄²⁻     1                   1na         2                   2  oh⁻       2                   2this equation follows the law of conservation of massanswer is 1st equation

Ihonestly don’t know how to use that one

If the distance between two charged objects decreases, both the electric and gravitational forces will increase.  this is due to the distance being in the denominator of both their equations.
