redox reactions deal with the transfer of electrons from one species to another species

redox reactions are made of reduction reactions and oxidation reactions

reduction reactions are when electrons take in electrons and results in a decrease in the oxidation number

oxidation reactions are when electrons give out electrons resulting in an increase in the oxidation number

therefore correct answer for reduction reactions are

(3) gain electrons and have a decrease in oxidation number

How many grams of Aspirin (acetylsalicylic acid) should we form in this reaction if we started with 2.08g of Salicyclic Acid?

Kamila [148]

Taking into account the reaction stoichiometry, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

C₄H₆O₃ + C₇H₆O₃ (Salicyclic Acid) →C₉H₈O₄ (aspirin) + C₂H₄O₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

C₄H₆O₃: 1 mole
C₇H₆O₃: 1 mole
C₉H₈O₄: 1 mole
C₂H₄O₂: 1 mole

The molar mass of the compounds is:

C₄H₆O₃: 102 g/mole
C₇H₆O₃: 138 g/mole
C₉H₈O₄: 180 g/mole
C₂H₄O₂: 60 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

C₄H₆O₃: 1 mole ×102 g/mole= 102 grams
C₇H₆O₃: 1 mole ×138 g/mole= 138 grams
C₉H₈O₄: 1 mole ×180 g/mole= 180 grams
C₂H₄O₂: 1 mole ×60 g/mole= 60 grams

<h3>Mass of aspirin formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 138 grams of salicyclic acid form 180 grams of aspirin, 2.08 grams of salicyclic acid form how much mass of aspirin?

$mass of aspirin=\frac{2.08 grams of salicyclic acidx 180 grams of aspirin}{138 grams of salicyclic acid}$

<u><em>mass of aspirin= 2.713 grams</em></u>

Then, 2.713 grams of aspirin are formed when 2.08 grams of salicyclic acid reacts.

What is a major problem with CFCs?

oksian1 [2.3K]

The major problem with CFCs is that It is a greenhouse gas, Option A is correct.

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine.

They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms

The major problem with CFC's is that they are green house gases

It destroys ozone in the upper atmosphere (stratosphere).

CFCs can produce more than 10,000 times as much warming, pound for pound, once they are in the air.

It is not only because of their dramatic warming potential but also

They were found to be the primary cause of the rapidly escalating destruction of the Earth’s ozone layer,

which protects the planet from dangerous, cancer-causing levels of ultraviolet radiation.

Therefore The major problem with CFCs is that It is a greenhouse gas, Option A is correct.
