- petrol has a Molar mass of 114 g.mol-1 and a ΔcH0 of -5470 kJ.mol-1. calculate the energy density of petrol in (in kJ.g-1)Consider the table.

- The tip of a scanning tunnelling microscope can be used to move atoms on a surface. The movement of atoms and ions depends on their ability to leave one position and stick to another, and therefore on the energy changes thatoccur. As an illustration, consider a two-dimensional square lattice of univalent positive and negative ions separated by 200 pm, and consider a cation on top of th is array. Calculate, by direct summation, its Coulombic interaction when it is in an empty lattice point directly above an anion.Two compounds are isomers if they have the same chemicalformula but different arrangements of atoms. Use Table 8.3to estimate ΔH for each of the following gas-phase isomerizationreactions and indicate which isomer has the lowerenthalpyWhat property of molecules allows them to change their threedimensionalshape?
- Calculate the electric dipole moment of a glycine molecule using the partial cha rges and the locations of the atoms as shown.Sara was in conversation with alexa and were discussing about how to measure theamount of energy generated by pizza they had during the breakfast under an oxygenatmosphere in a closed constant volume vessel. Being a chemistry student could yousuggest an instrument to measure the energy released along with its working principle?Your Question: In crystalline solids, atoms are arranged in periodic arrays. Theatoms themselves are fixed in place but can vibrate. You canimagine that the atoms in a crystal behave as if they areconnected to their neighbors by springs.These vibrations travel as waves called “phonons” (latticevibrations). The heat capacity of a crystalline solid arises fromthese vibrational degrees of freedom and is describedmathematically by the Debye law: Where N = Avogadro’s number, k = Boltzmann’s constant, and θ is the Debye temperature aconstant that is a metric of the stiffness of the “springs” and is correlated with mechanicalproperties of solids (i.e., mechanically softer solids tend to exhibit lower θ). a. Calculate the change in entropy associated with changing the temperature of diamondfrom 15 K to 100 K. (θ = 2230 K) b. The Debye temperature of gold (Au) is θ = 170 K. Calculate the entropy changeassociated with changing the temperature of solid gold from 15 K to 100 K. c. Compare your…
- Given the following data, calculate the normal boiling point for formic acid (HCOOH). DHf°(kJ/mol) S°(J/mol K) HCOOH(l) -410. 130.0 HCOOH(g) -363 251.1What is the trend for atom size from left to right across aperiod?The table below shows some physical properties of halogenatedliquids. Which of the following statements best explains these data?(a) The larger the dipole moment, the stronger the intermolecularforces, and therefore the boiling point is lowest for themolecule with the largest dipole moment. (b) The dispersionforces increase from F to Cl to Br; since the boiling point alsoincreases in this order, the dispersion forces must make a fargreater contribution to intermolecular interactions thandipole-dipole interactions. (c) The trend in electronegativityis F > Cl > Br; therefore, the most ionic compound (CH2F2)has the lowest boiling point, and the most covalent compound(CH2Br2) has the highest boiling point. (d) Boiling point increaseswith molecular weight for these nonpolar compounds.
