1. Predict the precipitate that forms when aqueous solutions of silver nitrate and potassium chloride react to form products in
2 answers:
Answer 1:
Explanation:
Double displacement reaction: It is a reaction in which reactants exchange their ions to form products in chemical reaction.
When aqueous solutions of silver nitrate and potassium chloride reacts together to form white precipitate of silver chloride with potassium nitrate in aqueous solution. While writing chemical reaction, first write the molecular formula of silver nitrate and potassium chloride with 'addition' sign in between(+) on the left hand side. Followed by right arrow and then the molecular formula of products formed on the right hand side
Answer 2: 1.69 moles of remained unreacted.
Explanation:
Number of moles of =
Number of moles of =
According to reaction , 1 mole of react with 3 moles of
, then 1.46 moles of
will react with :
moles of
that is 4.38 moles.
1.46 moles react with 4.38 moles of
. So, this means that
is present as limiting reagent. And
is an excessive reagent.
Moles of left unreacted :6.07 moles - 4.38 moles =1.69 moles
Hence,1.69 moles of remained unreacted.

The structural formula shown in the picture is the cyclic AMP or cyclic adenosine monophosphate. It is an essential component in RNA synthesis and metabolic processes. When it becomes non-cyclic after enzymatic reaction, you would have to disconnect the cyclic rings. When you do, you add 2 H atoms, one for each terminal end. The formula for cyclic AMP is C₁₀H₁₄N₅O₇P. Since there are three cyclic rings, you would have to add 6 hydrogen atoms. Thus, the formula for noncylic AMP is C₁₀H₂₀N₅O₇P.
