oxygen nitrogen hydrogen sulfur 2.) Select the three elements that are a part of ANFO, ammonium nitrate? 3 points

## Step 1: The first step is to understand what ANFO stands for. ANFO is an acronym for Ammonium Nitrate Fuel Oil. It is a type of explosive material composed of ammonium nitrate, a nitrogen-rich compound, and fuel oil. ## Step 2: Next, we need to identify the elements that make up ammonium nitrate. The chemical formula for ammonium nitrate is . ### The formula tells us that ammonium nitrate is composed of nitrogen (N), hydrogen (H), and oxygen (O).## Step 3: Finally, we compare the elements in ammonium nitrate with the options given in the question. The elements that are part of ANFO, ammonium nitrate, are oxygen, nitrogen, and hydrogen.
