When Carboxylic Acid is treated with Alcohols in the presence of acid as a catalyst it produces corresponding Esters. This reaction is called as Esterification.
 Also, this reaction is a reversible reaction and the ester formed can also hydrolyze to produce Carboxylic acid and Alcohol. This reverse reaction is called as transesterification.
The formation of Ethyl Acetate from Acetic Acid and Ethanol in the presence of acid is shown below,

Identify the chemical symbols corresponding to each element. drag the appropriate labels to their respective targets.
Shalnov [3]

The name and chemical symbol of the elements are

  • Carbon = C
  • Lead = Pb
  • Antimony = Sb
  • Sodium = Na
  • Aluminum = Al

<h3>What are chemical symbols?</h3>

Chemical symbols are which are used to represent the elements in the periodic table.

The chemical symbol assigned to elements are usually an abbreviation of the name of the element or the Latin form of the name.

The name and symbol of the given elements are as follows:

  • Carbon = C
  • Lead = Pb
  • Antimony = Sb
  • Sodium = Na
  • Aluminum = Al

The chemical symbols are used frequently in writing the formula of compound formed from the elements. For example, the compound sodium aluminate which contains sodium, aluminum and oxygen is written in a simplified form as: NaAlO₂.

AnnZ [28]

Answer: increase

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

As soda contains carbon dioxide dissolved in water.

The equation given by Henry's law is:

C_{CO_2}=K_H\times p_{CO_2}

where,

C_{CO_2} = solubility of carbon dioxide in water

K_H = Henry's constant

p_{CO_2} = partial pressure of carbon dioxide

Thus on increasing the pressure, the solubility of carbon dioxide also increase.

Identify ALL the possible mol ratio from<br> this balanced equation:
grandymaker [24]

Answer:

\frac{1 mole of N_{2} }{3 moles of H_{2} }

Explanation:

The equation of the reaction:

   Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;

 

          N₂    +    H₂    →    NH₃  

 The balanced equation is ;

        N₂    +    3H₂    →    2NH₃  

The mole ratio is the ratio of the coefficients of the combining reactants;

   1 mole of N₂ combines with 3 mole of H₂;

So;

      \frac{1 mole of N_{2} }{3 moles of H_{2} }
