In the standardization of NaOH, 38.76 mL of NaOH was required for 0.8169 g potassium acid phthalate. Estimate the accuracy we should expect in the molarity of the NaOH solution assuming the weighing error is ±0.1 mg, a buret reading error is ±0.02 mLbalance, and an additional uncertainty of ±0.03 mL using the indicator for the end-point determination.
Determine the number of significant digits in each number and write out the specific significant digits.
In the lower troposphere, ozone is one of the components of photochemical smog. It is generated in air when nitrogen dioxide, formed by the oxidation of nitrogen monoxide from car exhaust, reacts by the following mechanism.
Give a step by step mechanism for the reaction of the following: a. salicylic acid with acetic anhydride/ phosphoric acid b. salicylic acid with methanol/hydrochloric acid
The rate constant for a certain chemical reaction is 0.00250 M1 s1 at 25.0C and 0.0125 M1s1 at 50.0C. What is the activation energy for the reaction, expressed in kJ mol?
Structures of Acids, The chiral carboxylic acid A (C5H6O2) reacts with 1 mol of hydrogen gas on catalytic hydrogenation.
would be decomposed by a complete reaction with one drop of water? Assume that 1 drop ~ 0.05 mL. If you started with 0.4 g of trityl fluoborate, how much of it would have been left?
In 1986 an electrical power plant in Taylorsville, Georgia, burned 8,376,726 tons of coal, a national record at that time.
