2h2o + 2na ? 2naoh + h2 which of these is a reactant in this chemical reaction?

Water (H2O) and Sodium (Na) are reactants.

2H2O+2Na2NaOH+H2

In the above reaction the water (H2O) and sodium (Na) are reactants and sodium hydroxide (NaOH) and hydrogen are products.

And this is the single displacement reaction.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
