In the combustion chamber of an engine, the initial volume is 450 cm3 at a pressure of 1.0 atmosphere. if the piston displaces 402 cm3 of the total, what is the resulting pressure in the combustion chamber? (assume negligible temperature change.) hint: calculate the new volume by subtracting the amount of space the piston takes up from the initial volume. 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=

Kc = 0.040 for the system below at 450oc. if a reaction is initiated with 0.40 mole of cl2 and 0.40 mole of pcl3 in a 2.0 liter container, what is the equilibrium concentration of cl2 in the same system? pcl5(g) ⇄ pcl3(g) + cl2(g)
