Calculate the pH at the equivalence point if 25.00 mL of 0.010M barbituric acid (HC4H3N2O3) is titrated with 0.020M NaOH. (Ka barbituric acid = 1.0 x 10^-5)
How are finance and accounting related to an operating budget? where can I find information about this question. Basically I am asking how to break it down for easier searching any help is appreciated

The instructions are, Write Lewis structures that obey the octet rule for the following species. (Assign atomic charges where appropriate.) 1) XeO4 2) CIO^-4 3) PO4^-3 Would I just draw them in a different way or just the regular Lewis Structure?
Charged particles such as ions can separate the charges inside of overall electrically neutral atoms, thus making an electric dipole. A dipole is characterized with a dipole moment p=αEexternal, where α is the polarizability of an atom, and Eexternal is the external ...

2) Calculate the Molar Enthalpy of Neutralization (ΔHn) in kJ/mol of the reaction between a monoprotic acid and a monoprotic base, given the following information: The temperature change equals 5.06°C, 50.0 mL of 1.00 M concentration of Acid 50.0 mL of 1.00 M concentr...
I did show my work for #2 5*5*5.06*6.50= 822.25/4.180= 196.7
Not sure if these are right 1) What is the Molar Enthalpy of Neutralization (ΔHn) in kJ/mol if 5.00 moles of HCl(aq) (acid) neutralized 5.00 moles of NaOH(aq) (base) and released 13093 J of heat? 13093/5= 2618.6 then convert to kj 2) Calculate the Molar Enthalpy of Neutra...
