Answer:
The solvent is Nitrogen and the solute is oxygen
Explanation:
Normally the solvent always contains higher amount of substance than the solute in a particular solution
Mg + 2️⃣H20 ➡️ Mg(OH)2 + H2
Answer:
Pb²⁺(aq) --> Ni²⁺(aq)
Explanation:
The equation of the reaction is given as;
Ni(s) + Pb(NO₃)₂(aq) --> Pb(s) + Ni(NO₃)₂(aq)
In writing the ionic equation, we break the aqueous compound into ions. The solid and liquid compounds are ignored.
We have;
Pb²⁺(aq) + NO₃²⁻(aq) --> Ni²⁺(aq) + NO₃²⁻(aq)
Canceling the spectator ions;
Pb²⁺(aq) --> Ni²⁺(aq)
Every balanced chemical reaction demonstrates the law of conservation of mass where the reactants have the same number of atoms as the products. For example, the production of ammonia gas.
N2 (g) + 3H2 (g) -> 2NH3 (g) you can see that there are two nitrogen atoms and six hydrogen atoms on both sides of the equation.
