Agas mixture consists of 7 lbm of o2, 8 lbm of n2, and 10 lbm of co2. determine (a) the mass fraction of each component, (b) the mole fraction of each component, and (c) the average molar mass of the mixture. 2. determine the binary diffusion coefficient of o2 in nz at the following conditions (assume the mixture is dilute for all cases): (a) 200 k and 1 atm, (b) 400 k and 0.5 atm, and (c) 600 k and 5 atm.

3.) for each of the following compounds, draw the major organic product of reaction with hcl or naoh and circle whether the starting materials and products will be more soluble in organic solvent or water benzoic acid + hcl: benzoic acid + naoh: oh benzoic acid water/organic water organic fluorenone hс: fluorenone + naoh: fluorenone water/organic water/organic веnzocaine + hci: benzocaine + n»oh: h2n benzocaine water/organic water organic o=

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy) in an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect? ultraviolet light dim blue light bright red light bright yellow light
