The inverted cone, hope it helps .
Answer: By carrying out series of wet test
Explanation: Dissolve the ionic compound in water. Ionic compounds will ionise and allow the solution to conduct an electric current. Afterwards specific test will be carried out to detect the presence of cations and anions. Another way would be to find the substance's melting point. Ionically bonded compounds have much higher melting points.

Answer:
K₂S(s) → 2K⁺(aq) + S²⁻(aq)
Explanation:
A strong electrolyte is a compound that, in solution, dissociates completely. For a compound XₐYₙ that dissolves in water:
XₐYₙ(s) → aXⁿ⁺(aq) + nYᵃ⁻(aq)
Now, potassium sulfide (K₂S), as a strong electrolyte dissolves in water thus:
<em>K₂S(s) → 2K⁺(aq) + S²⁻(aq)</em>

Answer:
0.049 mol/L.s
Explanation:
The decomposition of hydrogen peroxide is:
![Rate = -\dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{ 2 \Delta [H_2O_2]}{\Delta t}](https://tex.z-dn.net/?f=Rate%20%3D%20-%5Cdfrac%7B%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D%3D%20%5Cdfrac%7B%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D%3D%20%5Cdfrac%7B%202%20%20%5CDelta%20%5BH_2O_2%5D%7D%7B%5CDelta%20t%7D)
The rate of decomposition reaction = the rate of formation of 
= 0.098 mol/L.s
∴
Rate of formation of 
= 0.049 mol/L.s
