I can’t see it can you write the problem ?
<span>10.2 grams of ethyl butyrate synthesized.
The balanced equation for the reaction of butanoic acid (C4H8O2) with ethanol (C2H6O) to produce ethyl butyrate (C6H12O2) is:
C4H8O2 + C2H6O ==> C6H12O2 + H2O
So for each mole of C4H8O2 used, 1 mole of C6H12O2 will be produced. So let's calculate the reactant and product molar masses. Start by looking up the atomic weights of the involved elements:
Atomic weight carbon = 12.0107
Atomic weight hydrogen = 1.00794
Atomic weight oxygen = 15.999
Molar mass C4H8O2 = 4 * 12.0107 + 8 * 1.00794 + 2 * 15.999 = 88.10432 g/mol
Molar mass C6H12O2 = 6 * 12.0107 + 12 * 1.00794 + 2 * 15.999 = 116.15748 g/mol
Moles C4H8O2 = 7.75 g / 88.10432 g/mol = 0.087963905 mol
Mass C6H12O2 = 0.087963905 mol * 116.15748 g/mol = 10.21766549 g
Rounding to 3 significant figures gives 10.2 grams of ethyl butyrate synthesized.</span>
Explanation:
Both (Photosynthesis and Cellular respiration)
Because
- In Cellular respiration energy is released in the form of ATP and In plants glucose stored in the form of energy.
- Plants are producers.
- Animals are consumers.
Therefore,
Both is correct✔
It’s B. Chromium(III) oxide
Arrhenius Acid:
Arrhenius Acid is any specie which when dissolved in water produces H⁺ (proton) Ions.
Nitrous Acid:
Nitrous Acid also acts as Arrhenius Acid when dissolved in water.
HNO₂ + H₂O → NO₂⁻ + H₃O⁺
Where,
H₃O⁺ ⇆ H⁺ + H₂O
As HNO₂ produces H⁺ Ions in water, so it is an Arrhenius Acid.
