The total number of moles of atoms that is present in 4.00 m o l e s of C O 2 has to be chosen from the given options. Concept Introduction: Chemical formula of a substance can be interpreted in two different ways, namely, in microscopic-level and macroscopic-level. Chemical formula at microscopic-level can be said as the one that indicates the number of atoms of different elements that is present in a formula unit or one molecule of substance. The numerical value present in subscripts in a chemical formula indicates the number of atoms of various elements that is present in one formula unit of substance. In macroscopic-level the chemical formula of a substance indicates the number of moles of atoms of different elements that is present in one mole of a substance. Conversion factors which relate a component of a substance to the substance as a whole are dependent on the chemical formula of the substance.

1. Show that the change in entropy for a fixed amount of ideal gas held at a constant temperature undergoing a volume change is given by the simple equation AS = NkB In Hint: Start with the equation M dS = du + (Œ) dv - Ž (#) an, dU du+av-dN; j=1 Why doesn't the equation for the entropy of an ideal gas depend on the strength of the intermolecular forces for the gas?

2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2 cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster. A. What is the work of expansion upon freezing? B. Is work done on the system or by the system?

I have a excitation/emission spectra of a quinine standard solution here, and I'm having trouble interpreting it. the red line is emission the blue line is excitation. i'm having trouble interpreting properly. just want to know if there is any evidence of raman or rayleigh peaks in the spectra.
