Iron and oxygen react together to make iron (iii) oxide (rust). you know that this is a chemical reaction and not a nuclear reaction because:

a large amount of heat is produced by the reaction
the individual atoms are rearranged but do not change identity
new products are formed as a result of the reaction
the rust has a greater mass than the iron and oxygen used to produce it

The individual atoms are rearranged but do not change identity

Explanation:

Hi, identity of an element is given by the amount of protons it has in its nucleous: two different elements must have different amounts of protons.

During a chemica reaction, such as the one between oxygen and iron, the atoms of the two elements create bonds but no a new element: they identities remain intact, so this is not a nuclear reaction

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.
