Explanation:
Since mole ratio of O2 : NH3 = 7 : 4,
Volume of NH3 = 50dm³ * 4/7 = 28.57dm³.
Answer:
<h2><em><u>starch, glycogen, and cellulose, are composed of glucose.</u></em></h2>
Explanation:
<h3><u>Starch is the main storage carbohydrate source in plants whereas cellulose is the main structural component of the cell wall of plants and glycogen is the main storage carbohydrate energy source of fungi and animals</u></h3>
The balanced equation for the reaction between H₂SO₄ and NaOH is as follows
2NaOH + H₂SO₄ ---> Na₂SO₄ + 2H₂O
stoichiometry of NaOH to H₂SO₄ is 2:1
stoichiometric point is also called the equivalence point. this is the point at which equal quantities of acid and base are added and all the H⁺ ions and OH⁻ ions react with each other.
the number of NaOH moles reacted - molar concentration x volume
number of NaOH moles = 0.3223 mol/L x 0.04556 L = 0.01468 mol
according to stoichiometry
2 mol of NaOH reacts with 1 mol of H₂SO₄
then 0.01468 mol of NaOH reacts with - 1/2 x 0.01468 mol = 0.007340 mol
the number of H₂SO₄ moles in 59.34 mL - 0.007340 mol
Therefore number of H₂SO₄ moles in 1000 mL - 0.007340 mol / 59.34 x 1000 = 0.1237 mol
molar concentration of H₂SO₄ is 0.1237 M
