Chapter 6.2, Problem 8E

(a)

Interpretation Introduction

Interpretation:

The Rf values of acetaminophen and caffeine should be determined.

Concept Introduction :

In chromatography, Rf value is the ratio between distance travelled by the component and distance travelled by the solvent front.

  Rf value = Distance travelled by the componentDistance travelled by the solvent front

(b)

Interpretation Introduction

Interpretation:

The ingredients in a tablet of Midol should be determined based on the TLC analysis.

Concept Introduction :

Thin layer chromatography is a separation technique used for non-volatile substances. Depending on the affinity of the component of the mixture to the stationary phase and mobile phase, distance travelled by each component on the TLC plate differ.

(c)

Interpretation Introduction

Interpretation:

The mobile phase and stationary phase in the TLC experiment should be determined.

Concept Introduction :

All chromatography techniques have a stationary phase and a mobile phase. Stationary phase is a solid, or a liquid supported on a solid. Stationary phase is not migrating. The mobile phase flows through the stationary phase and carries components along with it.

First I wanted to see if you would mind checking my graphs behind me. (They haven't been coming out right)? Second, could you help me explain if the rate of reaction is proportional to iodide and persulfate of each graph. I highlighted my answer and understanding but I'm not sure if I'm on the right track. Thank you in advance.
The heat of combustion for ethane, C2H6C2H6 , is 47.8 kJ/g. How much heat is produced if 1.65 moles of ethane undergo complete combustion?
Review of this week's reaction:  H2NCN (cyanamide) + CH3NHCH2COOH (sarcosine) + NaCl, NH4OH, H2O ----> H2NC(=NH)N(CH3)CH2COOH (creatine) Q7. Draw by hand the reaction of creatine synthesis listed above using line structures without showing the Cs and some of the Hs, but include the lone pairs of electrons wherever they apply.
