What is the difference between intermolecular hydrogen bonding and intramolecular hydrogen bonding? Apart from the spelling difference of couse - doubt my chemistry teacher would accept that as an...
How can I solve (x-2)(x^2+3x+1)=0 From the question: a) Show that (x-2) is a factor of f(x)=x^3 + x^2 -5x -2. b) Hence find the exact solutions of the equation f(x) = 0 I've managed to get to the last...
How do I find the percentage by mass ethanoic acid (CH3COOH) in the vinegar solution I have been given. Through titration I have found that the concentration of the vinegar is 8.45moldm-3, 0.21125...
