A very old and tired , grey haired AP Chem instructor wanted to determine the Ka of an unlabelled monoprotic acid in his stockroom. He dissolved an unknown amount of acid in an unknown amount of water and proceeded to titrate the sample with a solution of NaOH of unknown molar...
To find the y-intercept, plug in 0 for y and solve for x. 0=2x+2 2x=-2 x=-1 (0,-1) To find the x-intercept, plug in 0 for x and solve for y. y=2(0)+2 y=2 (2,0)
"The heat engine uses 1.00x10^-2 mol of a diatomic gas as the working substance. Determine the temperatures at the 3 points." From 1-2, it's an adiabatic process and the constants are (P)(V^(7/5)) or (T)(V^(2/5)). From 2-3, it's an isobaric process with V/T a...
Draw an open circuit that consists of 2 sets of 2 cells connected in series, connected in [arallel with each other. Add a variable resitance R1 in series with a set of 3 light bulbs r2, r3, r4 in parallel with each other. Insert an ammeter and a voltmeter in teh circuit
x+y+z=2 4x+5y+2=12 2x=4 solve using substitution
