1. What type of process is involved in going from element to compounds and vice versa?
Problem- Calculate the pH after addition of 40 mL of 0.150 M NaOH to (the original) 40 mL of 0.150 M acetic acid. This is a hydrolysis problem. All the acetic acid has been converted to acetate. The equilibrium will be that of the base, acetate. G..
In the NMR there is a peak at: singlet(1 Hydrogen at 9.5), triplet( 2 hydrogens at 2.5), quintet(2 hydrogens at 2), quintet or sextet( not clear)(4 hydrogens at 1.3), and triplet ( 3 hydrogens at 1).
Problem- A 2.5 g sample of French fries is placed in a calorimeter with 500.0 g of water at an initial temperature of 21°C. After combustion of the French fries the water has a temperature of 48°C. What is the caloric value (kcal/g) of the Frenc..
