Mass of H₂ needed to react with O₂ : 1.092 g
<h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
Reaction
O₂(g) + 2H₂(g) → 2H₂O(g)
mass of O₂ : 8.75 g
mol O₂(MW=32 g/mol) :
From the equation, mol ratio of O₂ : H₂ = 1 : 2, so mol H₂ :
Mass H₂ (MW=2 g/mol) :

Umm what do i do to help you??
7 is neutral on the pH scale
The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.
Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.
This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.
surplus reactant
This is the limiting reactant that is present in excess and reacts with it all. Oxygen in the surroundings, as an illustration.
When all of the reactant B has been utilized, the reaction ends.
