Answer:
H₃PO₄/H₂PO₄⁻ and HCO₃⁻/CO₃²⁻
Explanation:
An acid is a proton donor; a base is a proton acceptor.
Thus, H₃PO₄ is the acid, because it donates a proton to the carbonate ion.
CO₃²⁻ is the base, because it accepts a proton from the phosphoric acid.
The conjugate base is what's left after the acid has given up its proton.
The conjugate acid is what's formed when the base has accepted a proton.
H₃PO₄/H₂PO₄⁻ make one conjugate acid/base pair, and HCO₃⁻/CO₃²⁻ are the other conjugate acid/base pair.
H₃PO₄ + CO₃²⁻ ⇌ H₂PO₄⁻ + HCO₃⁻

<u>Answer:</u> The mass of the reactants is always equal to the mass of the products.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be formed nor be destroyed but it can only be transformed from one form to another. This law is followed by all the balanced chemical reactions.
This law simply means that the total mass on the reactant side is always equal to the total mass on the product side.
For example: Formation of water from hydrogen and oxygen gas.
Total mass on the reactant side =
Total mass on the product side =
As, the total mass on the reactant side is equal to the total mass on the product side. Hence, this equation follows law of conservation of mass.
