Answer:
Net ionic equation:
H⁺(aq) + OH⁻(aq) → H₂O(l)
Explanation:
Balanced Chemical equation:
HClO₂(aq) + NaOH(aq) → H₂O(l) + NaClO₂ (aq)
Ionic equation:
H⁺(aq) + ClO₂⁻(aq) + Na⁺(aq) + OH⁻(aq) → H₂O(l) + Na⁺(aq) + ClO₂⁻ (aq)
Net ionic equation:
H⁺(aq) + OH⁻(aq) → H₂O(l)
The ClO₂⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Answer:
c. ionic compound
Explanation:
Ammonium fluoride -
It is an inorganic salt , which has the molecular formula of .
As it is a salt , it is ionic in nature , i.e. , it has a cationic part and an anionic part , i.e. ,
is the cationic species .
And
is the anionic species.
is a crystalline solid , just like most of the salts , and has a very s alt salty taste to it.
Hence, from the given option ,
The correct option is ionic compound.
Ammonium fluoride is the inorganic compound with the formula NH4F. It crystallizes as small colourless prisms, having a sharp saline taste, and is exceedingly soluble in water.
Answer:
An aerosol is a colloidal A. liquid suspended in a C. gas.
Explanation:
When substances change state there is no change in mass. so for physical changes are generally easy to reverse though the end product may not always look exactly the same as the starting material.
