Which of the highlighted bonds absorbs at higher v in an IR spectrum? а. or OH H b. or c. -H or -H

50 ml of .2M KNO3 from 4.0 M stock solution

What volume of 0.12 M Na2SO4 will be required to react with 10 mL of 0.05 M CrCl6?

Please send me the question in 20 minutes it's very urgent plz

Write a procedure for making a supersaturated solution of KNO3?

The answer is 250mL and I am not understanding how. Please explain

4) A 25.00-mL sample of vinegar is diluted with deionized to 100.0 mL. Then a 10.00-mL aliquot (portion) of the dilute vinegar solutionis titrated with 0.1055 M NaOH solution using phenolphthalein as theindicator. (a) If 19.60 mL of the base solution is required to reach the end-point, calculate the molar concentration of acetic in dilute vinegar solution. (b) What is the molar concentration of acetic acid in the original (undiluted) vinegar? The acid-base reaction occurs as follows: HC2H3O2(aq) + NaOH(aq) --> H2O(l) + NaC2H3O2(aq)

___ Zn(s)  +  ___ HCl(aq)  -----> ___ ZnCl2(s)  +  ___ H2 (g)   Balance the equation above. If you perform this reaction with 30.0 mL of 4.50 M HCl and 20.5 grams of zinc, what volume of H2, measured at 740 mm Hg and collected over water 27.0oC, can be obtained?  (The vapor pressure of water at 27oC = 26.7 mm Hg) Zn = 65.38 g/mol HCl = 36.5 g/mol H2 = 2.0 g/mol

Caculate the volume (mL) of 1.0 M potassium carbonate (K₂CO₃) needed to prepare 5.0g of the COPPER pigment. This is where the balanced chemical equation come in. You should be able to relate the moles of pigment to the moles of K₂CO₃, and from that calculate the volume of 1.0 M K₂CO₃ solution needed.  Please report your value as XX.X mL (one deicmal point and no units).
