A 110.0 mL sample of a solution that is 3.0×10^?3 M in AgNO3 is mixed with a 220.0 mL sample of a solution that is 0.13 M in NaCN. After the solution reaches equilibrium, what concentration of Ag+(aq) remains?
Reaction/exchange rates of CO2 and O2 in the alveoli must be included. Given that the inhalation and exhalation times are different, calculate the rate of important gases during the inhalation and exhalation process.
Why must we know both in order to explain the physical properties of the molecule. physical properties to be considered are solubility and the points when the molecule changes states
15.0 moles of gas are in a 8.00 L tank at 21.0C. Calculate the difference in pressure between methane and an ideal gas under these conditions
do only ionic compounds dissolve with an evolution or absorption of heat...what about molecular compounds like sucrose, glucose, aspartic acid
