i am confused on which is the correct answer **Question:**Which one of the following combinations would NOT form a precipitate in aqueous solution?**Options:**A) LiNO₃ and NaOHB) AgNO₃ and KBrC) Zn(C₂H₃O₂)₂ and Na₂SD) Pb(NO₃)₃/₂ and Na₂SO₄E) All of the combinations will form precipitates.**Answer:**E) All of the combinations will form precipitates.**Explanation:**The question asks which combinations of chemical compounds, when mixed in aqueous solutions, would not form an insoluble product (precipitate). The correct answer indicates that all given combinations will result in precipitate formation.

In first option LiNO3 + NaOH = NaNO3 + LiOH, Here NaNO3 is a precipitate. In option 2 , AgNO3 + KBr = AgBr+ KNO3 Here, AgBr is precipitate. In option 3 , Zn(C2H3O2)2 + Na2S = ZnS + 2Na(C2H3O2) sodium acetate will be product , And it is very soluble in water. So this will not be considered as precipitate. But Zinc sulfide will also form as a product which is insoluble in water, so it will be precipitate. In option 4 , Pb(NO3)2 + Na2SO4 → 2 NaNO3 + PbSO4 Sodium nitrate and lead sulfate will be product, so Sodium nitrate will be precipitate here. Hence, option E is correct since all forms precipitate.

2) In a laboratory study, a calibration was performed using NH4C1 to analyze ammonium spectrophotometrically. The results of the study are given below. According to this, when the 5.0 mL sample containing ammonium is completed to 50 mL with pure water, find the amount of NH4 in the sample whose absorbance was found as 0.12 according to the table. (N: 14 g / mol, H: 1 g / mol, Cl: 35.5 g / mol). Concentration (mg/L) Absorbance 0.01 5 0.05 7.5 0.1 10 0.15 12 0.18
A protein’s concentration can be determined spectrophotometrically by mixing it with an indicator called a Bradford reagent and measuring the amount of light absorbed by the protein.

You have two solutions of the same compound that are blue. one is very pale and the other is very intense. Absorbance of each solution was measured with a spectrophotometer at the same wave length at which the solution absorbs. (A) Which solution has the higher absorbance? (B) Which is the more concentrated solution?
