Question

Смешали 14г порошкообразного железа с 14г поршкообразной серы смесь нагрели найдите массу сульфида железа с 14г если известно что Fe и s в данном случае соединяются в массовых отношениях 7:4

Answer 1

По условию 7 г железа реагирует с 4 г серы. Тогда 14 г железа вступит в реакцию с 8 г серы и получится 14+8=32 г сульфида

Answer 2

Calculation of the Mass of Iron Sulfide

To find the mass of iron sulfide (FeS) formed when 14g of iron (Fe) and 14g of sulfur (S) are mixed, we need to consider the mass ratio between Fe and S in the compound. According to the given information, Fe and S combine in a mass ratio of 7:4.

To calculate the mass of FeS, we can use the following steps:

1. Determine the mass of Fe and S in the mixture: - Mass of Fe = 14g - Mass of S = 14g

2. Calculate the mass of FeS using the mass ratio: - Mass of FeS = (Mass of Fe / Mass ratio of Fe) + (Mass of S / Mass ratio of S) - Mass ratio of Fe = 7 - Mass ratio of S = 4

Let's calculate the mass of FeS:

Mass of FeS = (14g / 7) + (14g / 4)

Mass of FeS = 2g + 3.5g

Mass of FeS = 5.5g

Therefore, the mass of iron sulfide (FeS) formed when 14g of iron and 14g of sulfur are mixed in a mass ratio of 7:4 is 5.5g
