Anwer: the first option, a hydrogen ion acceptor.

The acid-base model of Bronsted-Lowry is focused on hydrogen ion. An acid is a donor of hydrogen ions and a base is a receptor of hydrogen ions.

\boxed{{\text{A hydrogen ion accept or}}} describes a Bronsted-Lowry base.

Further Explanation:

Different theories have definitions of acids and bases. These theories are as follows:

1. Arrhenius theory: According to this theory, acid produces hydrogen or hydronium ions in a solution, while the base produces hydroxide ions in a solution. HCl, {\text{HN}}{{\text{O}}_3} and  {{\text{H}}_2}{\text{S}}{{\text{O}}_4} are Arrhenius acids while NaOH and KOH are the examples of Arrhenius bases.

2. Bronsted-Lowry theory: This theory defines acid as the proton or hydrogen ion donor and base as the proton or hydrogen ion acceptor. {{\text{H}}_2}{\text{O}} acts as Bronsted acid while {\text{N}}{{\text{H}}_3} is a Bronsted base.

3. Lewis theory: According to this theory, an acid accepts a pair of electrons from electron-rich species while a base donates electrons to electron-deficient species in the reaction. Examples of Lewis acids are {\text{B}}{{\text{F}}_3}, {\text{S}}{{\text{O}}_3} while {{\text{H}}_2}{\text{O}} and ROH are the examples of Lewis base.

A hydrogen ion acceptor

According to Bronsted-Lowry theory, Bronsted-Lowry base is the species that accepts protons or hydrogen ions. So this is incorrect.

An electron pair donor

A compound that donates an electron pair act as Lewis base, not Bronsted-Lowry base. So this is incorrect.

An electron pair acceptor

A compound that accepts an electron pair act as Lewis acid, not Bronsted-Lowry base. So this is incorrect.

A hydrogen ion donor

According to Bronsted-Lowry theory, the species that donates protons or hydrogen ions is known as Bronsted-Lowry acid, not base. So this is incorrect

All elements are made up of atoms. ➢ Atoms are made up of protons, neutrons, and electrons. Two different kinds of atoms can combine to form a compound. A molecule is a combination of atoms that cannot be broken apart while still retaining the same properties as the larger substance that it is a part of.

A bomb calorimeter has a heat capacity of 783 J/oC and contains 254 g of water whose specific heat capacity is 4.184 J/goC. How
IrinaK [193]

Answer : The amount of heat evolved by a reaction is, 4.81 kJ

Explanation :

Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water

q=[q_1+q_2]

q=[c_1\times \Delta T+m_2\times c_2\times \Delta T]

where,

q = heat released by the reaction

q_1 = heat absorbed by the calorimeter

q_2 = heat absorbed by the water

c_1 = specific heat of calorimeter = 783J/^oC

c_2 = specific heat of water = 4.184J/g^oC

m_2 = mass of water = 254 g

\Delta T = change in temperature = T_2-T_1=(23.73-26.01)=-2.28^oC

Now put all the given values in the above formula, we get:

q=[(783J/^oC\times -2.28^oC)+(254g\times 4.184J/g^oC\times -2.28^oC)]

q=-4208.28J=-4.81kJ

Therefore, the amount of heat evolved by a reaction is, 4.81 kJ

What is the change in internal energy ( ΔU ) of the system if q = –8 kJ and w = –1 kJ for a certain process?
Radda [10]

Answer:

Change in internal energy (ΔU) = -9 KJ

Explanation:

Given:

q = –8 kJ [Heat removed]

w = –1 kJ [Work done]

Find:

Change in internal energy (ΔU)

Computation:

Change in internal energy (ΔU) = q + w

Change in internal energy (ΔU) = -8 KJ + (-1 KJ)

Change in internal energy (ΔU) = -8 KJ - 1 KJ

Change in internal energy (ΔU) = -9 KJ
