Question

___Na+__H2O➡️__NaOH+__H2In a experiment, 2.35g of Na react with 7.25 g of H2O1) write the formula for the reactant that is the limiting reactant

Answer 1

Explanations:

Given the unbalanced chemical reaction expressed as:

`aNa+bH_2O\rightarrow cNaOH+dH_2`

The balanced chemical reaction will be expressed as:

`2Na+2H_2O\rightarrow2NaOH+H_2`

Given the following

Mass of Na = 2.35g

Mass of H2O = 7.25g

Determine the moles of the elements

Moles of Na = Mass/Molar mass

Moles of Na = 2.35/.35
