Answer:
#3 is the percentage for sodium i believe and 4 is right
Explanation:
The products and the reactants are the components of the reaction. The equation of phosphoric acid represents the decomposition reaction as it forms oxygen and water. Thus, option a is correct.
<h3>What is a decomposition reaction?</h3>
A decomposition reaction is a chemical breakdown of the reactant into two or more products. The large and complex compound breaks into smaller and simpler molecules.
The following equation, 4 H₃PO₄ → P₄ + 5 O₂ + 6 H₂O is an example of decomposition as phosphoric acid breaks into phosphorus, water, and oxygen molecules.
Therefore, option a. the reaction of phosphoric acid is a decomposition reaction.

#SPJ1
Water combines with carbon dioxide to produce slightly acidic groundwater
that dissolves limestone and forms caves.
This is because the reaction between water and carbondioxide to form
bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen
atoms thereby increasing the acidity.
The acidic environment results in the formation of acidic groundwater that
dissolves limestone and forms caves.
