From the ln [reactant] as a function of temperature you can tell the reaction rate is first order if it is a linear curve ln[A]t = -kt + ln[A]o How is this equation derived?ORPick ONE from the list below and define and explain:
1. What are liquid crystals and how do they work and what are they used for?
2. What is femptochemistry and what application is it useful for?
3. What is reverse osmosis? How does it work and how is it used?
Complete the chemical equation that show the release of hydroxide ions as each of the following bases dissolves in water:
A 2.00g sample of a particular compound was dissolved in 15.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85 Celcuis.
A 24.9 mL volume of HCl reacts completely with 55.0 mL of aqueous Na2CO3. The reaction is as follows:2HCl (aq)+ Na2CO3(aq)-> CO2(g)+H2O(l)+2NaCl(aq)
1. Why was excess dry ice used in step 3 of the procedure? 2. Why do gas laws use degrees Kelvin rather than degrees Celsius? 3. Were you surprised at how accurately the mass of a molecule of CO 2 could be determined With such simple equipment?
Which of the following is the correct pH of a 211.7 mL solution (final volume) of pure water after 52.3 mL of 1.00 mM HCl was added
what is the volume percent of a solution prepared by dissolving 43 g of NaOH in enough water to make a final volume of 120 ml.
What is the pH of 1.0 x 10^-4 M phenol where ka = 1.3 x 10^-10? This is a weak acid under dilute conditions. You need to take into account water self-dissociation to find the hydronium concentration.
