Why would it be difficult to determine the climate of a place based on one days measurements

Use the gizmo to find the concentration of the mystery ch3cooh. use the titrant and indicator shown below perform the titration. what is the titrant volume? titrant analyte indicator titrant volume analyte concentration naoh ch3cooh phenophthalein select one: a. 20.0 ml b. 27.0 ml c. 30.0 ml d. 24.0 ml

What reaction is taking place? 02 + c3h8 = h20 + co2

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
