If the seller anticipates receiving $52, then the company must create at least $102in order to be Marginal benefit Although they sound similar, marginal revenue and marginal benefit are not the same thing.

In actuality, it's the opposite. Marginal benefit measures the benefit to the customer of consuming an additional unit of a good or service, whereas marginal revenue measures the additional money a company makes by selling one additional unit of its good or service. The incremental improvement in a consumer's benefit that results from consuming one more unit of a good or service is known as the marginal benefit. As more of a good or service is consumed, it typically declines. Consider a consumer who wishes to purchase a new dining room, for instance.

How does the size of a berrylium atom compare with the size of oxygen?
Illusion [34]
Oxygen is fairly smaller than beryllium. The two have the same amount of orbital shells, but oxygen has more protons, which pulls its electrons closer together, thus decreasing the overall size.

Table below shows the electronegativities of four elements. Which of the following bonds is the most polar?
Contact [7]

 Lets find the electronegativity difference between the bonded atoms;

C-H = 2.6-2.2 = 0.4

C-F = 4.0-2.6  = 1.4

F-F = 4.0-4.0   = 0

H-O = 3.4-2.2  = 1.2

Here the electronegativity difference is highest for C-F bond hence C-F bond is most polar.

Draw the conjugate acid of ethanol
Snezhnost [94]

Answer:

H₃O⁺.

Explanation:

Hello,

In this case, ionization of ethanol yields hydrogen cations and ethoxide anions as follows:

CH_3COOH+H_2O\rightleftharpoons H_3O^++CH_3COO^-

Which is at equilibrium as ethanol is a weak acid. Thus, since the conjugate acid is formed by the outgoing H⁺ and the water, we say that the conjugate acid is then the hydroxonium ion, H₃O⁺ whereas the conjugate base is the remaining anion CH₃COO⁻.

Best regards.
