Hydrolysis of Methyl Benzoate yields Benzoic Acid and Methanol. This reaction is also called as Tranesterification (reverse of esterification). Acid in this reaction protonates the carbonyl oxygen, resulting in increasing electrophillic character of carbonyl carbon. Water acts as a nucleophile and methoxide leaves as a good leaving group. Mechanism is shown below,

HELP FOR FINAL

Dahasolnce [82]

Volume of CO₂ obtained : 13 L

<h3>Further explanation</h3>

Reaction

C₂H₅OH + 3 O₂ ⇒ 2 CO₂ + 3 H₂0 + 8842 Joules

moles of ethanol=0.28

From equation, mol ratio ethanol : CO₂ = 1 : 2, so mol CO₂ :

$\tt \dfrac{2}{1}\times 0.28=0.56$

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

Then volume of CO₂ :

$\tt V~CO_2=mol\times 22.4=0.56\times 22.4=12.544\approx 13~L$

ILL GIVE A BRAINLY PLS HELP

Atoms are the unit of the molecule of the compound. The 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water and 3 moles of carbon dioxide in the sample.

<h3>What are atoms?</h3>

Atoms are the smallest fundamental unit of the compounds that can be given by Avogadro's number.

For calculating the oxygen atoms in 5 mole water:

If 1 mole = 6.02 × 10²³

Then, 5 moles = 5 × 6.02 × 10²³

Hence, 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water.

Moles of carbon dioxide in the sample is calculated as:

If 1 mole of carbon dioxide = 6.02 × 10²³ molecules

Then moles in 1.8 x 10²⁴ molecules will be,

(1.8 x 10²⁴ molecules) ÷ (6.02 × 10²³ molecules) = 3 moles

Hence, 3 moles of carbon dioxide is present in the sample.

Carbon-12 is the most common isotope of carbon. It has 6 protons, 6 neutrons, and 6 electrons. Of its 6 electrons, 4 are valence

ra1l [238]

I think the correct answer from the choices listed above is option B. <span>Of its 6 electrons, 4 are valence electrons, a carbon atom can form 4 covalent bonds with other elements. It is the 4 valence electrons available that allows this.

Hope this answers the question.</span>
