Interpretation Introduction

Interpretation:

Plot of log(molecularmass) versus retention time has to be plotted and the equation of straight line has to be evaluated. Molecular mass for the unknown with the retention time 13.00min has to be plotted.

Concept Introduction:

Polystyrene is a synthetic polymer that is made of aromatic hydrocarbon styrene. Molecular weight of each repeated unit is 104.1gmol1. The plot of  log(molecularmass) versus retention time is a straight line for polystyrene polymer.

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.
