A sample of 11.0g of sodium is reacted with 18.6g of water to produce sodium hydroxide and hydrogen gas. Using the balanced equation below, predict which is the limiting reactant and the maximum amount in moles of hydrogen gas that can be produced.

b. is the answer hoped i        

the answer is c i took the test

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
