A positive sum of the two half-reactions' standard potentials

What does the VSEPR theory tell about a molecule

What is an emample of a chemical change

The following are indicators of chemical changes: ... For example, changing the color of a metal does not change its physical properties.

An avalanche demonstrates what kind of energy conversion

Gravitational potential energy to kinetic energy

In the reaction FeCl2 plus 2NaOH gives iron II hydroxide plus 2NaCl 6 moles of FeCl2 are added to 6 moles of NaOH how many moles of FeCl2 would be used up in the reaction

FeCl2(aq) + 2NaOH(aq) --> Fe(OH)2(s) + 2NaCl(aq)Thus 2 moles of sodium hydroxide react with every mole of iron(II) chloride.

Here we have only enough sodium hydroxide to react with 3 moles of iron(II) chloride.
