The functional groups are written in the pictures attached. The first picture is aspirin. The functional groups are carboxylic group(O=COH), ester (O=COR), and aromatic group (benzene ring), where R is any hydrocarbon chain. The second picture is acetaminophen. The functional groups are amide group (O=CNHR), hydroxyl group (ROH) and aromatic group (benzene ring).
Zirconium cannot be broken down by a chemical change, because it is an element. The others are all molecules.
<h3><u>Answer;</u></h3>
Step 1; NaHCO3(s) + CH3COOH(l)
Step 2 ; CO2(g)
<h3><u>Explanation;</u></h3>
- The chemical equation for the reaction of baking soda (sodium bicarbonate, NaHCO3) and vinegar (acetic acid, CH3COOH) reaction occurs in two steps.
Step 1;
- A double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
- Equation;
NaHCO3(s)+ CH3COOH(l) → CH3COONa(aq) + H2CO3(l)
Step 2;
- Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3(l) → H2O(l) + CO2(g)
