In an effort to maximize the efficiency of a propane barbeque, the oxygen to fuel ratio is altered. In two different trials the following two reactions were observed.
Trial I
C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g)
Trial II
2 C3H8(g) + 7 O2(g) → 2C(s) + 2CO(g) + 2CO2(g) + 8 H2O(g)
1. Identify the following variables in this experiment.
Manipulated
Responding
Question: Which of these would be the manipulating and controlled variable and how can you tell?
If 329 g water at 65.7°C loses 9730 J of heat, what is the final temperature of the water?
if you were monitring the titation by visivle spectroscopy what wavelength would you select for the data analysis? why?
A solution of I- gives 301.0 mV in a cell with an iodide ion selective electrode. 10.0 mL of the solution is mixed with 3.00 mL of 1.00 x10^-6 M AgNO3, and the Ag is completely precipitated as AgI. The cell then gives 310.2 mV. Assume the electrod..
