2Mg + O2 ---> 2MgO
Magnesium burns in air forming magnesium oxide
The word equation for the formation of hydrogen gas is "Hydrogen gas is produced by the reaction of a metal with an acid."
The balanced equation for the reaction between hydrogen gas (H2) and oxygen gas (O2) to produce water (H2O) is: 2H2 + O2 -> 2H2O
An example of a chemical equation with water as a reactant is the reaction between hydrogen gas and oxygen gas to form water: 2H2 + O2 -> 2H2O.
The gas constant in the Arrhenius equation helps to account for the effect of temperature on reaction rates. It is a constant value that relates the energy of the reacting molecules to the rate of the reaction.
When iron reacts with sulfuric acid, hydrogen gas is evolved. The word equation for this reaction is: Iron + Sulfuric acid -> Iron sulfate + Hydrogen gas. To indicate the gas evolved in the reaction, one can place a downward arrow (↓) next to the hydrogen gas in the products.

The equation for making ammonia is N2 + 3H2 -> 2NH3. This chemical reaction involves the combination of nitrogen gas and hydrogen gas to form ammonia gas.
The reaction is: Ca + 2H2O = Ca(OH)2 + H2
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
The word equation for the reaction in which stalactites and stalagmites are produced is: calcium bicarbonate in water reacts with carbon dioxide gas to form calcium carbonate, water, and carbon dioxide gas.
2 parts hydrogen gas reacts with 1 part oxygen gas in the air to form water vapor. combustion 2H2 + O2 ---------> 2H20
