The absorption for an internal alkyne will be more intense than the absorption for a terminal alkyne.
For our experiment we put 5 mL of red Kool-Aid in an empty 25 mL volumetric flask, we then slowly added water until it reached the 25 mL mark in the flask and recorded our observations. Obviously the red Kool-Aid was diluted by the water making it..
If a vessel containing NO2 has an initial concentration of 2.8 x 10-2 mol/L, how long will it take for 75 of the NO2 to decompose? The decomposition of NO2 is second order in the reactant and the rate constant is 1.1 L/mol x s.
what is the concentration of (HOCl), at equilibrium if 0.0230 mol of H2 and 0.0230 mol of ClO2 are initially placed in a 5 L vessel? What is the concentration of ClO2 in the above problem at equilibrium?
Consider the reaction CaCN2 + 3H2O ->CaCO3 + 2NH3 . How much NH3 is produced if 187 g of CaCO3 are produced?
what mass of water would you need to evaporate from your skin in order to dissipate 1.7 x 105 j of heat from your body?
benzene (C6H6) has a characteristic ultraviolet spectrum. Using the molecular orbital theory, account for this uv spectrum.
Calculate the molarity of S2O32- if 3.0 mL 0.10 M K2S2O8, 2.0 mL 0.10 M K2SO4, 1.0 mL 2% starch, 2.0 mL 0.010 M Na2S2O3, and 5.0 mL 0.20 M KI are mixed.
Complete and balance the equation for this reaction in basic solution. Phases are optional.
