Problem- 0.550 L of 0.470 M H2SO4 is mixed with 0.500 L of 0.220 M KOH. What concentration of sulfuric acid remains after neutralization?
I need help for above question. Show each steps for the above problem.
A 35.0-mL sample of 0.20 M LiOH is titrated with 0.25 M HCl. What is the pH of the solution after 23.0 mL of HCl have been added to the base?
Consider an aqueous solution that is 0.934 M in FeCl2 (MW = 126.752 g/mol) with a density of 1.31 g/mL. Calculate the molality, mass percent, and mole fraction (?) of FeCl2 in this solution. The MW of H2O is 18.02 g/mol.
When ethane (C2H6) reacts with chlorine (Cl2) the main product is C2H5Cl; but other products containing Cl (chlorine), such as C2H4Cl2, are also obtained in small quantities. The formation of these other products reduces the yield of C2H5Cl. In a ..
Problem- Consider a reaction with two competing pathways. One is labeled as the kinetic pathway while the other is labeled as the thermodynamic pathway. How could you use temperature to favor the kinetic pathway over the thermodynamic pathway. Why
