These are dissolved in water to form colourless solutions, and then mixed together. This mixing leads to a double displacement reaction, essentially resulting in the metals 'swapping' their places in the two compounds, producing lead (II) iodide, and potassium nitrate.
You can automatically rule out CH₄ since it has no lone pairs at all around the central atom. Water has 2. Ammonia is the only Lewis structure that contains one lone pair.
A bright feild is most commonly used
Melting is an example of phase change
Answer:
It is basic.
Explanation:-
Given hydrogen ion concentration [H+] = 1×10^-12
Using the formula
pH = - log [H+]
= - log [ 1 x 10^-12]
= 12
Since the pH is more than 7, the chemical is basic
