Draw the product that is formed when the compound shown below is treated with an excess of HCl. Draw only the organic ion.
A solution is prepared from 0.95 grams of H3PO4 ,(Phosphoric acid) and 1.15 grams of HClO4 (perchloric acid) in 150 mili litres of solution then determine how many milliliters of 0.425 M sodium hydroxide( NaOH) is needed.
A hypothetical atom has four allowed energy levels. As shown in the accompanying diagram, the emission spectrum of this atom will contain six transitions, labelled A - F.
Assuming an ideal solution, what is the molecular mass of the compound?
What molarity of aqueous magnesium chloride solution can be expected to show the same conductivity
The following data were obtained when measuring the delta H of neutralization for the reaction of HCl with NaOH.
Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs
Draw resonanc contributors for the following species. Indicate which are major contributors and which are minor contributors to the resonance hybrid:
Draw four structures corresponding to dihedral angles of 0, 60, 120 and 180 degrees. Clearly indicate the best and worst in this set.
what would happen to the molar mass of the solute if the thermometer used actually read 1.4 degrees Celsius too high?
what is the maximum pressure that will be attained in the tank before the plug will melt and release gas?
In the lower atmosphere, oxygen gas is converted to ozone gas by energy provided from lightening as shown in the reaction below and the value of the equilibrium constant for this reaction at 25C is Kc = 1.7 x 10^-56.Equation
