Copper is :
which one of the following will displace copper from a solution of copper sulphate? a- al b- Fe c-Mg d- all of these e- non of these
In an experiment 1.288g of copper oxide was obtained from 1.03g of copper. In another experiment 3.672g of copper oxide obtain from the 2.938g of copper. Show that these figures verify the law of constant proportion.
1.2 g of copper powder on heatinf gave 6.0 g of copper oxide. In another experiment, copper oxide contained 20% oxygen. Show that these results illustrate the law of constant proportion.
In an experiment 4.90g of copper oxide was obtained from 3.92g of copper . In another experiment 4.55g of copper oxide gave on reduction 3.64g of copper . Show with the help of calculations that these figures verify the law of constant propotions.
