You should find that copper has been reduced from +2 to +1; oxygen (in the gas) has been reduced from 0 to -2 (oxygen in the SiO 2 is unchanged); and three of the four sulfurs on the left-hand side have been oxidized from -2 to +4 (the other is unchanged).

The copper metal turns black when it is heated in the burner. When the metal is placed in the H 2 atmosphere inside the funnel, it returns to the original copper color. The copper oxide can then react with the hydrogen gas to form the copper metal and water. When the funnel is removed from the hydrogen stream, the copper was still be warm enough to be oxidized by the air again.

List each subshell, and then fill each subshell with an appropriate number of electrons until all electrons in the element are accounted for. Transition elements have electrons in the d orbital, which introduces some additional nuance in the electron configurations.

It details the calculations for comparing copper quantities that combine with a fixed mass of chlorine, emphasizing the significance of these ratios in understanding compound composition and encouraging further exploration of mass ratios and molecular formulas.

This similarity in electron structure makes them similar in many characteristics. All have very high thermal and electrical conductivity, and all are malleable metals. Among pure metals at room temperature, copper has the second highest electrical and thermal conductivity, after silver.

It discusses electrical potential in voltaic cells, emphasizing that it's measured in volts and depends on half-cell differences. A complete redox reaction, illustrated by a zinc-copper cell, determines this potential, with copper ions being reduced due to their higher reduction potential compared to zinc.

Extensive properties, such as mass and volume, vary with the amount of matter, while intensive properties, like electrical conductivity and color, do not depend on sample size. Examples are provided to clarify these definitions, highlighting the distinction that extensive properties change with quantity, whereas intensive properties remain constant regardless of the size of the sample.

The process uses copper sulfate and a copper anode to ensure consistent copper ion concentration, with the possibility of using other metals like chromium, gold, silver, and platinum in the technique.
