using the law of conservation of matter, determine the number of grams of iron sulfide (fes) that will be produced in this reaction.

112g fe + 64g s → g fes

a) 48 grams

b) 64 grams

c) 112 grams

d) 176 grams

D = 176 g

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

Fe + S   →   FeS

112g + 64 g = 176 g

In given photosynthesis reaction:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.
