when heated, sulfuric acid will decompose into sulfur trioxide and water. Write a chemical equation, using words, to represent this chemical reaction. Identify reactants and products.

Question

(I'm having trouble identifying the reactants and products & writing the chemical equation in words. Also isn't the product ALWAYS on the right hand side with an arror point to the right.)

Answer 1

I'm not sure why you're having trouble. The question WRITES the word equation for you.
sulfuric acid + heat gives sulfur trioxide and water.
reactants on left; products on right.

H2SO4 + heat ==> SO3 + H2O.
I cant writ eh heat sign over the arrow but that's the way it is usually done and often heat is designated with a capital Greek letter delta.
