What is the name given to the property of metal that allows electricity to pass through.

Hypothesis for isotopes and atomic mass

The decomposition of hydrogen peroxide is given by the following reaction:2 H2O2 (aq) → 2 H2O (l) + O2 (g) In the presence of KI the reaction is thought to occur by the following mechanism:Step 1: H2O2 + I - → H2O + IO-Step 2: IO - + H2O2 → H2O + O2

An early method of producing hydrogen gas was passing steam through red-hot iron pipes according to the reaction 3 Fe (s) + 4 H2O (g) → Fe3O4 (g) + 4 H2 (g) How many liters of hydrogen gas at STP can be created by reacting 15.3 g of iron?
