3Fe + 4H2O 1Fe3O4 + 4H2 2.55 x 1025 molecules of H2O will combine with Fe to produce g H2.

124 g of Fe will combine with H2O to produce formula units of Fe3O4.

2.24 moles Fe will fully react with g of H2O.

78.0 g of H2O will react with Fe to produce formula units of Fe3O4.

9.25 x 1023 formula units of Fe will react with H2O to produce moles of H2.

i look it up online and i'll tell you

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
