Answer: Nitrogen normally exists as two-atom molecules in the form of a gas at room temperature.
Explanation:
The net ionic equation is
Ag⁺(aq) +Cl⁻(aq) → AgCl(s)
Explanation
AgNO₃ (aq) + KCl (aq)→ AgCl(s) +KNO₃(aq)
from above molecular equation break all soluble electrolyte into ions
Ag⁺(aq) +NO₃⁻ (aq) + K⁺(aq) +Cl⁻(aq) → AgCl (s) + K⁺(aq) + No₃⁻(aq)
cancel the spectator ions in both side of equation =K⁺ and NO₃⁻ ions
The net ionic equation is therefore
= Ag⁺(aq) + Cl⁻(aq) → AgCl(s)
a) double-displacement
Explanation:
We have the following chemical reaction:
Na₂S (aq) + Cd(NO₃)₂ (aq) → CdS (s) + 2 NaNO₃ (aq)
where:
(aq) - aqueous
(s) - solid
This chemical reaction is a double-displacement reaction because the reactant exchange atoms or group of atoms between themselves. The reaction is driven to right by the formation of the precipitate. The general representation for this kind of reaction is: AB + CD → AC + BD
In a synthesis reaction two elements will combine to form a compound.
2 H₂ + O₂ → 2 H₂O
In a single-displacement reaction an atom or group of atoms from a compound is displaced by another atoms. The general representation for this kind of reaction is: A + BC → B + AC
