What is the equation for Coulombic force and why is it important in chemistry? 4. What is the charge on the chloride ion and why does it have this charge
You obtain the following six measurements for the mass of water delivered by a special calibrated volumetric pipette
the order of the reaction was n=0 and the value of the rate constant was 3.41*10^-3 M s^-1. I could find the order of reaction and the value of the rate constant but I am clueless about how to find the rate of reaction when [A]=0.15M.
For the reaction 2A + B --> 2C, if B is initially 4.0M and 2min later is 3.0M, what is the rate of appearance of C?
Develop a detailed calorimetric method for determining the temperature of the warm water sample.
What volume (in milliliters) of 0.100 M NaOH should be added to a 0.120 L solution of 0.024 M glycine hydrochloride
During the late 1800's, hard rock miners replaced candles with carbide lamps for work in mine shafts. The lamps worked by dripping water onto calcium carbide that generated acetylene gas (H2C2) that was burned.
Which of the following compounds is expected to have the highest boiling point? octane, 2,3-dimethylhexane, 2,2,3,3-tetramethylbutane
