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

In this reaction n2o4(g)→2no2(g) what changes in color would you expect as pressure is increased at a constant temperature

Tell me the iupac names of the following alcohols:

Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
