No, they both refer to the ratio of moles in compounds of a chemical reaction. Along with mole ratio and molar ratio, this can also be called the mole-to-mole ratio.

Answer:
The correct options are: 1. Ca²⁺ and 4. Mg²⁺
Explanation:
Hard water is the water with high mineral content. Temporary hardness and permanent hardness are the two types of hardness of water.
Temporary hardness is due to the presence of dissolved bicarbonate minerals. These minerals present in the water, dissociate to give multivalent calcium cations (Ca²⁺) and magnesium cations (Mg²⁺).
<u>Therefore, the presence of metal cations such as calcium cations (Ca²⁺) and magnesium cations (Mg²⁺) makes the water hard.</u>
The question needs:
In a 1 M solution of N₂H₄(aq), identify the relative molar amounts of these species. from most to least...
H₂O N₂H₅⁺~OH⁻ H₃O⁺ N₂H₄
H₂O is most
second N₂H₄
N₂H₅ and OH⁻ present in equal amount
H₃O⁺ is zero
because N₂H₄ is weak base it partially ionizes in water as following:
N₂H₄ + H₂O ⇄ N₂H₅⁺ + OH⁻
