the partial pressures of ch4, n2, and o2 in a sample of gas were found to be 143 mmhg, 469 mmhg, and 251 mmhg, respectively. calculate the mole fraction of oxygen.

How many molecules of sucrose c12h22o11 are there in 454 grams of sucrose

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon

A50.0 ml sample of gas at 20.0 atm of pressure is compressed to 40.0 atm of pressure at constant temperature. what is the new volume? 0.0100 ml 0.325 ml 25.0 ml 100. ml
