What is the SDS for regular bleach? Physical state, route of exposure and symptoms, required protective equipment, first aid procedures, fire-fighting measures.
Displays the volume and pH at which equivalence was reached and plots this point on the graph and validates the code by plotting the midpoint using both methods and displaying the volume and pH for both methods in the Command Window.
Given a 0.010 M solution of a diprotic acid H2A with Ka1 = 2.9 x 10-5 and Ka2 = 5.3 x 10-6. The species present in the lowest concentration is
Calculate the pH of the solutions formed by dissolving 1.0g of each of the following substances in 500mL of solution
If 10.7 mL of .110 M NaOH is required to reach the equivalence point of a solution of citric acid, how many mL of NaOH are required to completely neutralized this solution
Draw the skeletal structure of the given molecules given that each atom obeys the octet/duet rule and no atom possesses a formal charge, for the molecule whose condensed structure is (a) (CH3)2CHCHCHC(CH3)3
What is the pH at the equivalence point when when 25.0mL of 0.100M hypochlorous acid (HClO) is titrated with 0.200M KOH. Ka HClO = 2.9*10^-8 It asks that all appropriate equations be included.
Explain what type of radiation, such as ultraviolet, visible, or infrared would be needed to cause ionization of the hydrogen atom. Briefly explain
In a lab, you are given a block of aluminum. You measure the dimensions of the block and its displacement in a container of a known volume of water.
Calculate the quantity of energy produced per mole of -235 (atomic mass = 235.043922 ) for the neutron-induced fission of -235 to produce -137 (atomic mass = 136.9253 ) and -97 (atomic mass = 96.910950 ).
Define a container holds 355mL of a mixture of nitrogen and carbon dioxide gases. Compute the partial pressures of each gas if the container is at 27.3oC
what are the allowable transitions from 4d to 5f of hydrogen atoms using the quantum numbers l and m to indicate the allowable transitions
A student completes a titration of an unknown diprotic acid. In this experiment, 0.79 g of the acid is dissolved in 250.0 mL of water. It requires 13.48 mL of 1.0 M NaOH to reach the second equivalence point. What is the molar mass of the acid
