What are the conjugate base and conjugate acid for HSO4−? What is the term used to describe species that can behave as either an

acid or a base, depending on the chemical environment?

Answer:

Conjugate acid- H^+

Conjugate base- SO4^2-

Terminology- Amphoteric

Explanation:

Consider the equilibrum shown below;

HSO4^-(aq)<-------> H^+(aq) + SO4^2-(aq)

Hence, When HSO4^- is dissolved in aqueous solution, it's conjugate acid is H^+ and it's conjugate base is SO4^2- as shown in the equation above.

If a substance behaves both as an acid and as a base, then the substance is Amphoteric in nature.

Burning one gallon of gasoline releases 20 pounds of CO2 into the air. Harry’s compact car can travel 25 miles on one gallon of
son4ous [18]
There are several information's already given in the question. Based on those information's, the answer can be easily deduced.
Amount of gasoline required by Harry's car to travel 25 miles = 1 gallon
Then
amount of gasoline required
by Harry's car to travel 15000 miles = 15000/25
                                                         = 600 gallons
So 
Amount of CO2 released by burning 1 gallon of gasoline = 20 pounds
Then
Amount of CO2 released
by burning 600 gallon of gasoline = 600 * 20
                                                      = 12000 pounds
From the above deduction, it can be concluded that the amount of CO2 that will be added by Harry's car to the atmosphere is 12000 pounds.

Which best describes the field of chemistry?
qaws [65]

Answer:

Fundamentally, chemistry is the study of matter and change. The way that chemists study matter and change and the types of systems that are studied varies dramatically. Traditionally, chemistry has been broken into five main subdisciplines: Organic, Analytical, Physical, Inorganic, and Biochemistry.

hope this helps :)

Estimate the enthalpy change for the combustion of one mole of acetylene, C2H2, to form carbon dioxide and water vapor. BE(C?H)
tia_tia [17]

Answer:

ΔH rxn =  -1010 kJ/molC₂H₂

Explanation:

To obtain the enthalpy change for a reaction from bond energies what we do is to make an inventory of the bonds broken and formed for the balanced chemical reaction:

C₂H₂ + 5/2O₂   ⇒   2CO₂ + H₂O

Bond Broken                                    Bonds Formed

2 C-H + 1 C≡C + 5/2 O=O                4C=O + 2 H-O

Enthalpy bonds broken:

2 mol (456 kJ/mol)+ 1 mol (962 kJ/mol) + 5/2 mol (499 kJ/mol)  =  3121.5 kJ

Enthalpy bond formed:

4 mol (802 kJ/mol) + 2 mol (462 kJ/mol) = 4132.0 kJ

ΔH rxn = H broken - H formed =  3121.5 kJ - 4132.0 kJ = - 1010  kJ (per mol C₂H₂ )

A certain sample of a liquid has a mass of 42 grams and a volume of 35 centimeters3. What is the density of the liquid?
BabaBlast [244]

Answer:

            1.2 g.cm⁻³

Solution:

Data Given:

                             Mass  =  42 g

                             Volume  =  35 cm³

Formula Used:

                             Density  =  Mass ÷ Volume

Putting values,

                             Density  =  42 g ÷ 35 cm³

                             Density  =  1.2 g.cm⁻³
