I need help figuring out the flowchart and if I have the right
answers for the prelab please and thank you!
Group I, the Chloride Group BACKGROUND The precipitating reagent for the chloride group is chloride ion in an acidic solution. Only three of the 18 metal ions form a precipitate with this reagent: silver ion (Ag'), mercury(I)ion (Hg). and lead ion (Pb). Since lead chloride is somewhat soluble, it is not completely precipitated here, and a low concentration of...

For the prelab questions I have some answers but I don’t know
if they’re right. If they’re wrong, I would greatly appreciate an
explanation for the correct answer. I’m really trying to learn the
material but it’s hard now that classes are cancelled so I’m sorry
if these are dumb

U sullulllcu tos to NO 4. A student mistakenly added concentrated (12M) HCI to a sample of unknown, instead of adding 6M HCI, as directed. (1) At first, a large amount of light-colored pre- H cipitate formed, but some dissolved on further addi- tion of concentrated HCI. Write an equation(s) for the reaction(s) that might have occurred.

Explain Only #2,#3,#4 per Le Châtelier and whether the #2,#3,#4 reaction moves Left or Right 1.Silver carbonate equilibrium. In a 150-mm test tube add 10 drops of 0.01 M AgNO3 to 10 drops of 0.1 M Na2CO3. Add drops of 6 M HNO3 to the precipitate until evidence of a chemical change occurs. Record your observations. Explain them based on the equation below. (Caution: 6 M HNO3 reacts with the skin!) Ag2CO3(s) ⇌ 2 Ag+ (aq) + CO3 2-(aq) CO3...
