States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Figure 7 of Conrad et al. (1999) shows the variation in C-isotopic composition of CO2 as a function of the concentration of methane measured in the soil and aquifers of a site contaminated in the residues of aviation fuels. Explain briefly the aim of these particular measurements made to the environmental study. Also explain briefly why there is a difference in isotopic composition of CO2 obtained via aerobic degradation and methanogenic degradation of AVGAS (fuel residues as contaminants) and the linear “mixing relationship” noted in Figure 7. How does the degradation process influence the CO2 isotopic signature ? I don't understand why the CO2 from aerobic degradation is lighter than the one from methnogenic degradation ?
A student was given an unknown polymer sample made either of Nylon 6,6 or poly(ethylene terephthalate): ENH -OH any port Nylon 6,6 H- Poly(ethylene terephthalate) The student measured its MW and degree of polymerization and found them to be 27,120 g/mole and 120 respectively. Which polymer is the sample made from? Oa. Nylon 6,6 b. Poly(ethylene terephthalate) c. Neither Od. Both because the sample is made of a copolymer.
A solution of DNA of unknown concentration (termed "[unknown] DNA solution") gave an absorbance value of 0.39 at 260 nm. The goal here is to determine the DNA concentration of this [unknown] DNA solution. To calculate this, you are given the following additional information: A DNA solution whose concentration is 50 ug/ml has an absorbance value of 1.0 at 260 nm. Using this information and knowing that A1/C1 = A2/C2 i. Calculate the DNA concentration (ug/mL) in the DNA solution of [unknown] ii. iii. iv. Once you have determined the DNA concentration of [unknown] DNA solution, calculate how many ug of DNA would be present in 25 μl of this DNA solution If you dilute the "[unknown] DNA solution" 10-fold, i.e. 1/10, what will the absorbance value (at 260 nm) of the diluted solution be? What will the new concentration of DNA of the diluted solution be?
