An unknown weak monprotic acid with the general formula HA has a Ka=5.5 x 10^-7. what is the value of the equilibrium constant that describes the following reaction? A- +H2O = HA +OH-
An automobile antifreeze mixture is made by mixing equal volumes of ethylene glycol (d=1.114 g/mL; M=62.07 g/mL) and water (d=1.00 g/mL) at 20 degrees C. The density of the mixture is 1.070 g/mL. Expreess the concentration of ethylene glycol as volume percent. I've tried t...
A baker uses sodium hydrogen carbonate as the leavening agent in a banana nut quickbread. the baking soda decomposes according to two possible reactions. 1. 2 NaHCO3 = Na2CO3+H2O+CO2 2. NaHCO3+H=H2O+CO2+Na. calculate the volume in mL of CO2 that forms at 180 degrees C and .975...
on a particularly hot 30 degrees C day near the seashore the partial pressure of water vapor in the air is .0303atm. given that the atmospheric pressure is 1 atm and the composition of dry air is 78% N, 21% O and 1%Ar, what is the partial pressure of oxygen gas?
