Answer:
H₂O + Na → NaOH + H₂
Step-by-step explanation:
Firstly, a skeleton equation does not reflect the relative amount of reactants and products. A skeleton reaction only identifies the reactant and product by their chemical formula but it does not quantify them. A skeleton chemical equation is simply described as an unbalanced equation.
The question asked for the correct skeleton reaction of water and sodium to produce sodium hydroxide and hydrogen.
Let us represent them with their chemical formula
Water → H₂O
Sodium → Na
Sodium hydroxide → NaOH
Hydrogen → H₂
The skeleton reaction will be
H₂O + Na → NaOH + H₂
