Which of the following statements would be true if you have 50 molecules of both H2 and O, available for the reaction shown? 2H2(g) + O2(g) → 2H2O(g)
a. Hy is the limiting reagent and 50 molecules of water are formed.
b. O, is the limiting reagent and 100 molecules of water are formed.
c. neither H2 nor Oz is limiting
d. none of the statements are true

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
