HI
So, the formula for water is H2O
When you have the same amount of the reactants , hydrogen will be the limiting reactant.
Limiting reactant is the thing that runs out first.
Answer:
The answer would be oxygen.
Missing question: <span>The decomposition of </span><span> XY is second order in </span><span>and has a rate constant of 6.96×10</span>⁻³ s⁻¹<span> at a certain temperature.
c</span>₀ = 0,050 M.
t = 55 s.
k = 6.96×10⁻³ s⁻¹.
Integrated second
order rate law is: 1/c₁ =
1/c₀<span> + k·t.
</span>1/c₁ = 1/0,050 M + 0,0069 s⁻¹ · 55 s.
1/c₁ = 20,38 1/M.
c₁ = 0,049 M.
