Answer:

The answer is D) Electrolytic cell

Explanation:

An electrolytic cell is a device used for the decomposition by the electrical current of ionized substances called electrolytes.

When the two electrodes are connected by a wire, electrical energy is produced, and a flow of electrons takes place from the electrode.

These cells are the closest thing to a galvanic battery.

A) What volume of concentrated nitric acid (15.8 M) is needed to prepare 4.0 L of a 2.0 M solution?

azamat

Answer:

A.0.51L

B 1.67L

Explanation:

using the formula ;C1V1 =C2V2

15.8×V1=2×4

15.8V1=8

V1=8/15.8

V1=0.51L

apply the same method for B

Use Coulomb's Law to explain why and how atomic radius and IE have an inverse relationship.

VladimirAG [237]

Answer:

Such a relationship between atomic number and atomic radius is a direct correlation. an inverse correlation. According to Coulomb's Law, as the atomic number increases within a series of atoms, the nuclear attraction for electrons will also increase, thus pulling the electron(s) closer to the nucleus.

A 350. mL air sample collected at 35 degrees C has a pressure of 556 mm Hg.

SashulF [63]

Answer:

485 torr

Explanation:

Explanation:

We can solve this equation using the combined gas law:

P1V1/T1=P2V2/T2

Remember, always use the absolute (Kelvin) temperature when working with gas equations.

The temperature conversions are

T1=C+273=35o+273=308K

T2=57C+273=330K

Since we're trying to find the final pressure, let's rearrange this equation to solve for

P2:

P2=P1V1T2/T1V2

Our known values:

P1= 550 torr

V1=350mL

T1=308K

V2=425"mL

T2=330K

Let's plug these into the equation to find the final pressure:

The final pressure after it is subjected to these changes is thus 485torr
