Balanced Chemical Equation – Solution

Ca + 2H2O → Ca(OH)2 + H2

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

Calcium + Water = Portlandite + Tritium

This is an oxidation-reduction (redox) reaction. H2O is an oxidizing agent, Ca is a reducing agent.

  • 2 HI + 2 e– → 2 H0 (reduction)
  • Ca0 – 2 e– → CaII (oxidation)

Reaction Type

Single Displacement (Substitution)

Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.

Reactants:

Ca

  • Names: Calcium.
  • Appearance: Silvery-white-to-grey powder.

H2O – Water, oxidane

  • Other names: Water (H2O), Hydrogen oxide, Hydrogen hydroxide.
  • Appearance: White crystalline solid, almost colorless liquid with a hint of blue, colorless gas.

Products:

Ca(OH)2 – Calcium hydroxide

H2

  • Names: Dihydrogen, Hydrogen.
  • Appearance: Odourless colourless compressed gas.
