These two
chemicals ___ with each other at a certain temperature to produce a substance
witch could cause an explosion.

  1. Interact


  1. React


I have
checked these two word in the dictionary and found that both of them can be
used to describe chemical change.

Here are
the examples:

1.Perfume interacts with the skin's natural
chemicals.

2.Iron reacts with water and air to produce rust.

Thank you
for you reply!

Hi,

They are certainly both possible here.

Here are a couple of comments on how I see these words.

react - produce an effect on each other, with a suggestion of conflict

interact - work together to produce an effect, with a suggestion of co-operation
