1 answer:
Answer:
Ammonium chloride
Explanation:
The powder is:- Ammonium chloride
When mixed with silver nitrate, white prescipitate of silver chloride is formed as:-
When mixed with sodium hydroxide, ammonia gas is formed which has noxious order.

Answer : The moles of formed are, 22.3 moles.
Explanation : Given,
Moles of = 16.72 mol
The given chemical reaction is:
From the balanced chemical reaction, we conclude that:
As, 3 moles of react to give 4 moles of
So, 16.72 moles of react to give
moles of
Therefore, the moles of formed are, 22.3 moles.
<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>
<em>• Acid rain if the [H +] is 1.9 x 10-5 </em>
<em>• Sulfurous acid if [H +] = 0.10 </em>
<em>• Nitric acid if [H +] = 0.11</em>
<em />
<h3>Further explanation </h3>pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
- pH acid rain
- pH Sulfurous acid
- pH Nitric acid
