In the chemical equation: NO(g) + ½Cl2(g) → NOCl(g) How many moles of NOCl(g) are in the balanced chemical equation? fill in bla
2 answers:
<u>Answer:</u> The coefficient of NOCl in the given balanced chemical equation is 1
<u>Explanation:</u>
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
Every balanced chemical equation follows law of conservation of mass
For the given balanced chemical equation:
By Stroichiometry of the reaction:
1 mole of nitrogen monoxide gas reacts with moles of chlorine gas to produce 1 mole of NOCl
Hence, the coefficient of NOCl in the given balanced chemical equation is 1

Answer:
3,78 mL of 12,0wt% H₂SO₄
Explanation:
The equilibrium in water is:
H₂O (l) ⇄ H⁺ (aq) + OH⁻ (aq)
The initial concentration of [H⁺] is 10⁻⁸ M and final desired concentration is [H⁺] =
Thus, you need to add:
[H⁺] = = <em>5,31x10⁻⁸ M</em>
The total volume of the pool is:
7,00 m × 18,0 m ×1,50 m = 189 m³ ≡ 189000 L
Thus, moles of H⁺ you need to add are:
5,31x10⁻⁸ M × 189000 L = 1,00<em>x10⁻² moles of H⁺</em>
These moles comes from
H₂SO₄ → 2H⁺ +SO₄²⁻
Thus:
1,00x10⁻² moles of H⁺ × = <em>5,00x10⁻³ moles of H₂SO₄</em>
These moles comes from:
5,00x10⁻³ moles of H₂SO₄ × ×
×
= <em>3,78 mL of 12,0wt% H₂SO₄</em>
<em></em>
