Elemental calcium reacts with water at room temperature to form calcium hydroxide and hydrogen gas as shown in this equation. Sodium undergoes a similar reaction with H2O. What would be the coefficient for sodium in a similar reaction?

Respuesta :

transitionstate
Reaction of Elemental Calcium with Water is as follow,

                        Ca  +  2 H₂O    →    Ca(OH)₂  +  H₂↑

When Sodium Metal is reacted with Water it produces NaOH and eliminates Hydrogen gas as shown in following equation,

                         2 Na  +  2 H₂O    →    2 NaOH  +  H₂↑

In both cases corresponding Hydroxides along with Hydrogen gas is produced.
