Introduction: This report discusses an experiment to study the percent mass of iron determined by the concentration of a colored iron solution from the absorbance of the spectrometer. This lab is designed to tell the content of iron in cereal, usually food products list iron a...

Can some one read my lab report for me... I have it almost finished.. I just need help on the discussion part Please
Lauren
Fe(s) is an element right
Lauren
So I need to find the Hf of each of those equations
Lauren
Which of the following has a standard enthalpy of formation value of zero at 25 degrees C and 1.0 atm A. Fe(s) B. Fe2O3(s) C. FeSO4(s) D. FeSO4(aq) E. FeS3(s) and what is enthalpy or how do you find it
Lauren
The amount of heat required to raise temperature of 55.85 g of iron 1 degrees C is called its A. Change of energy B. Enthalpy C. Molar heat capacity D. Specific heat capacity E. Specific Heat.
Lauren
Use Lewis symbols to represent the electron transfer between the following atoms to give ions with noble gas configuations: A. Mg and S B. Ba and I
Lauren
Arrange the following in order of increasing ionic radius: I^-, Cs+, and Te^2-. Explain this order
Lauren
correct thank you for the help
Lauren
so in my book there is a chart but there is not a number for it so I can see which has a larger radius what is another way to tell which is larger they both have a 3- charge
