Explanation:

Desalination of seawater is considered a renewable source of water, although reducing its dependence on fossil fuel energy is needed for it to be fully renewable.

Write a mechanism for the esterification of propanoic acid with 18O-labeled ethanol. Show clearly the fate of the 18O label. (b)

tatuchka [14]

Answer:

See explanation and images attached

Explanation:

a) In the mechanism for the acid catalysed esterification of propanoic acid using ethanol, we can see that the first step is the protonation of the acid followed by nucleophillic attack of the alcohol. Loss of water and consequent deprotonation regenerates the acid catalyst. We can see the fate of the 18O labelled ethanol in the mechanism shown.

b) In the second mechanism, an unnamed ester is hydrolysed using an acid catalyst. The attack of the acid and subsequent nucleophillic attack of water labelled with 18O leads to the incorporation of this 18O into the product acid as shown in the mechanism attached to this answer.

When iron metal reacts with sulfuric acid, it produces iron (III) sulfate and hydrogen gas. Balance the equation: Fe + H2SO4 → F

uranmaximum [27]

Taking into account the law of conservation of matter, the balanced reaction is:

2 Fe + 3 H₂SO₄ → Fe₂(SO₄)₃ + 3 H₂

First, you must know that the law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. This is, balancing a chemical equation is to equalize the number and class of reactant atoms, ions or molecules with the products, in order to comply with the law of conservation of mass.

For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

This is because the subscripts that are placed on chemical symbols or formulas indicate the number of atoms that make up the substance. If the coefficients are modified, the quantities of the substance change, but if the subscripts are modified, different substances are originated.

In this case, the balanced reaction is:

2 Fe + 3 H₂SO₄ → Fe₂(SO₄)₃ + 3 H₂
