Identify the type of Chemical reaction:

H₂SO₄ + 2 NaOH > 2 H₂O + Na₂SO₄

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Answer explanation

This is a double replacement reaction because the H and OH join to make H2O and the Na and SO4 join to make Na2SO4.

They traded partners.

This can be tricky because SO4 does not break apart, but acts as a single element. Polyatomic compounds like Sulfate (SO4) do not usually break apart during a reaction and should be treated like an element.

Identify the type of Chemical reaction:

AB > A + B

Identify the type of Chemical reaction:

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Answer explanation

Even though there are more than 2 products made, this is decomposition.

Why?

Because one compound is broken down into parts, those parts don't have to be individual elements.
