Question- What is the density of a Neon nucleus assuming a typical size for a nucleus and assuming a spherical nuclear shape?
This is the question for that you have to provide expert solution
what is the literature value for the Ksp of potassium hydrogen tartrate in water at 10, 22.5, 35, 50 degrees?
Formic acid (HCOOH) is secreted by ants. Calculate [H3O+] for a 7.40E-3 M aqueous solution of formic acid (Ka = 1.80E-4).
Problem- We found a theoretical spectrum of HCl for FTIR. Now assume that the isotope Cl 37 was used to generate the same spectrum. How would this heavier mass affect the spacing between the signal peaks?
What is the value of Kc for the decomposi- tion of ammonium carbamate into ammonia and carbon dioxide?
A certain element consists of two stable isotopes. The first has atomic mass of 7.02 amu and a percent natural abundance of 92.6%.
Solve for the new pressure in each of the following, with n and V constant: 1)A gas with a pressure of 1.25 atm at 90 Celsiusis cooled to -17 Celsius. 2)A sample of N2 with a pressure of 790 mm Hg at -75 Celsius is heated to 34 Celsius
theoretically feasible in a solution that initially 0.250 M in each ion? c.) If separation is feasibe in eithee (a) or (b), what ranfe of anode potential (vs. SCE) should be used?
A 0.0560 g quantity of acetic acid is dissolved in enough water to make 50.0 mL of solution. Calculate the concentration of H+, CH3COO-, and CH3COOH at equilibrium. Ka for acetic acid= 1.8x10^-5.
which solution would create the higher osmotic pressure compared to pure water- one prepared from 1.0g of nacl in 10 ml
Calculate the molarity of your unknown, assuming it is monoprotic acid or monobasic base. Show all calculations for one titration with good precision including units and correct number of significant figures.
When the reaction 2 H2S g ~ PCl3 + Cl2 is carried out at 1065 degrees celcius, Kp = 0.012. Starting with pure H2S at 1065degrees, what must the initial pressure of H2S be if the equilbrated mixture at this temperature is to contain 0.250 atm of H2..
