The structure of copper is described as a lattice of positive ions in a 'sea of electrons'.
Which statements are correct?
1 Copper has a high melting point because of the strong electrostatic attraction
between the positive ions and the 'sea of electrons'.
2 Copper is malleable because the layers of atoms in the lattice can slide over each
other.
3 Copper atoms can be oxidised to form copper ions by losing electrons.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
