how many mL of 0.5 NaOH solution is needed to react completely with all the copper (II) sulphate in solution. Then titrate ¼ of the estimated amount number of mL of NaOH needed to react with the sulphate solution. Then add 5 mL at a time NaOH until Cu(OH)2 precipitate does not form. Record the correct number off mL which forms to NaOH solution. Fold the filter paper and stick inside the funnel‚ and pour the solution of copper (II) hydroxide through the filter.

BEAN BAG ISOTOPES:ABUNDANCE AND ATOMIC MASS LAB Prelab A new atomic theory‚ in which all atoms of the same element are identical to one another and equal in mass‚ was proposed by the scientist Dalton. Although the theory had its flaws and was simple‚ it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon‚ isotopes were discovered‚ as atoms of the same element which have been built up to have different masses. Purpose

How effective were the Vietcong tactics of underground tunnels and booby traps in the Vietnam War? The Vietnam War was a war that started during the late 1950s and ended during the late 1970s. The Vietnam War ended in the Vietcong victory over America. I believe that this was due to the underground ‘labyrinth’ of tunnels and the vast usage of guerrilla warfare used by the Vietcong. Their usage of the tunnels and booby traps were in my opinion ingenious. The variety of the booby traps that were
