Concept explainers
Interpretation:
The reason for carbon to be a solid, not a gas needs to be explained.
Concept introduction:
The physical properties of any substance represent its nature. There are different types of matter based on physical properties.

Answer to Problem 9E
Solids have closely arranged atoms, with negligible inter-atomic space and the maximum force of attraction between particles gives them a perfect shape.
Explanation of Solution
Carbon is a solid, as it occurs in many organic and inorganic compounds. It exists as allotropes like Diamond, Graphite and as the main constituent of coal, petroleum, etc. All the elements can be classified based on their physical states like solid, liquid and gas. Carbon is a non-metal, located in the periodic table in group 14. It is solid at room temperature. It forms covalent bonds with similar atom and other atoms also.

- Using iodometry I want to titrate a sodium thiosulfate solution and I use 15 mL. If I have 50 mL of a 0.90 M copper solution and KI, what will be the molarity of sodium thiosulfate?arrow_forwardDraw the product formed when the following pair of compounds is treated with NaOEt in ethanol. + i CNarrow_forwardI need help with the followingarrow_forward
- I need help with the followingarrow_forwardFor Raman spectroscopy/imaging, which statement is not true regarding its disadvantages? a) Limited spatial resolution. b) Short integration time. c) A one-dimensional technique. d) Weak signal, only 1 in 108 incident photons is Raman scattered. e) Fluorescence interference.arrow_forwardUsing a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40. a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L) b) Calculate the molar absorptivity, a, of the 1645 cm-1 band c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c. (Please provide a full derivation of the equation for x from the equation for I). d) Calculate x for the 1645 cm-1 bandarrow_forward
