At a fixed volume, a four-fold increase in the temperature of a gas will lead to _______ in pressure.
timofeeve [1]

Answer:

D) a four-fold increase

Explanation:

According to Gay-Lussac's law, which states that the pressure of a given amount of gas is directly proportional to the temperature at a constant volume, the pressure increases with an increase in temperature.

According to this question, at a fixed volume, a four-fold increase in the temperature of a gas will lead to a four-fold increase in the pressure as well.

Hydrogen sulfate reacts with water to produce sulfate ions and hydronium ions: hso4−+h2o⇌so42−+h3o+ identify the conjugate acid-
Angelina_Jolie [31]
The generic equation for a reaction between an acid and water is 

     HX_{(aq)} + H_{2}O_{(aq)} --> X_{(aq)}^{-} + H_{3}O_{(aq)}^+

When an acid "reacts" with water, water acts as the base that accepts the proton (H+) from the acid. The remaining ion that is formed after the acid has donated its proton is called the conjugate base (X^-), and the conjugate acid-base pair is HX - X^-. 

Hydrogen sulfate (HSO_{4}^-) is an ion from sulfuric acid. It is still an acid in itself and can "react" with water ((H_{2}O) to form the sulfate (SO_{4}^2-) and hydronium (H_{3}O^+)ions. 

HSO_{4(aq)}^{-} + H_{2}O_{(aq)} --> SO_{4(aq)}^{2-} + H_{3}O_{(aq)}^+

Based on the previous discussion, SO_{4(aq)}^2- is identified to be the conjugate of the acid HSO_{4(aq)}^-. Thus, the conjugate acid-base pair is HSO_{4(aq)}^{-} - SO_{4(aq)}^{2-}.

Why are metals generally good conductors of electric current?
lakkis [162]

Answer:

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.

The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.
