Answer:
4.06 mol H₂O
Explanation:
- 2C₆H₁₄ + 19O₂ → 12CO₂ + 14H₂O
First we <em>convert the given masses of reactants into moles</em>, using <em>their respective molar masses</em>:
- 250 g O₂ ÷ 32 g/mol = 7.81 mol O₂
- 50 g C₆H₁₄ ÷ 86 g/mol = 0.58 mol C₆H₁₄
Now we <u>calculate how many O₂ moles would react completely with 0.58 C₆H₁₄ moles</u>, using the <em>stoichiometric coefficients of the reaction</em>:
- 0.58 mol C₆H₁₄ *
= 5.51 mol O₂
As there are more O₂ moles than required (7.81 vs 5.51), O₂ is the reactant in excess. That means that <em>C₆H₁₄ is the limiting reactant</em>.
Now we can <u>calculate how much water can be formed</u>, using <em>the number of moles of the limiting reactant</em>:
- 0.58 mol C₆H₁₄ *
= 4.06 mol H₂O
A chemical property of soda ash is that it is an alkaline compound , of pH 11.6 in aqueous solution. The chemical name of soda ash is sodium carbonate. It is a sodium salt of carbonic acid and occurs as a white crystalline compound. It has a cooling alkaline taste. It can be found in the ashes of many plants. It is produced in large quantities from sodium chloride (common salt). It can be found as a mineral in mineral deposits of natron usually in seasonal lakes when the lakes dry up.
In the Bronsted-Lowry acid-base definition, an acid is a molecule (or ion) that donates a proton and a base is a molecule (or ion) that accepts a proton.
Bronsted-Lowry theory of acid and bases took the Arrhenius definition one step further, as a substance no longer needed to be composed of hydrogen (H+) or hydroxide (OH-) ions in order to be classified as an acid or base. For example , consider the following chemical equation:
HCl (aq) +NH₃ (aq) → NH⁺₄ (aq) + Cl⁻(aq)
Here, hydrochloric acid (HCl) "donates" a proton (H+) to ammonia (NH3) which "accepts" it , forming a positively charged ammonium ion (NH4⁺) and a negatively charged chloride ion (Cl⁻). Therefore, HCl is a Bronsted-Lowry acid (donates a proton) while the ammonia is a Bronsted-Lowry base (accepts a proton). Also, Cl⁻ is called the conjugate base of the acid HCl and NH4⁺ is called the conjugate acid of the base NH3.
A Bronsted-Lowry acid is a proton (hydrogen ion) donor.
A Bronsted-Lowry base is a proton (hydrogen ion) acceptor.
In this theory, an acid is a substance that can release a proton (like in the Arrhenius theory) and a base is a substance that can accept a proton.
