<u>Answer and Explanation:</u>
Mercury combines with sulfur as follows -
Hg + S = HgS
Hg = 200,59
S = 32,066 Therefore 1.58 g of Hg will react with -
1.58 multiply with 32,066 divide by 200,96 of sulfur.
= 0.25211 g S
This will form 1.58 + 0.25211 g HgS = 1.83211 g HgS
The amount of S remaining = 1.10 - 0.25211 = 0.84789 g
Basically for the first question, it’s 470.58 grams of potassium nitrate. Then for the second, it’s 0.34 moles of potassium nitrate. I hope the work makes sense!
Answer: Magnet
Explanation:Using a magnet is the best separating technique to be deployed in this case. The nails are easily picked out by just holding a magnet over the sandbox.
Hello!
The precipitate of the reaction that occurs <span>when a silver nitrate solution is mixed with a sodium chloride solution is silver chloride (AgCl).
The chemical equation for this precipitation reaction is the following:
AgNO</span>₃(aq) + NaCl(aq) → AgCl↓(s) + NaNO₃(aq)
Silver Chloride is a chemical compound that is poorly soluble in water because the chemical bond between Ag⁺ and Cl⁻ is very strong as the two ions are nearly the same size and have similar electronic densities. If the chemical bond is strong, it is more difficult for water molecules to break this bond to surround the individual ions, and thus solubility will decrease.
Have a nice day!
A.) Average acceleration = change in velocity/time = final velocity - initial velocity/time = 10-0/4 = 10/4 = 2.5m/s^2.
