Answer:

Ag is both reduced and the oxidizing agent.

Explanation:

Ag is the answer for both

Cu + AgNO₃ → Ag + CuNO₃

Cu is a reducing agent, and AgNO3 is an oxidizing agent.

In a chemical process, an oxidizing agent, also known as an oxidant, obtains electrons and becomes reduced. The oxidizing agent often referred to as the electron acceptor, is typically in one of its higher oxidation states since it will receive electrons and be reduced.

In a chemical process, a reducing agent, also known as a reductant, loses electrons and is oxidized. The electron donor is a reducing substance, which is normally in one of its lower oxidation states. A reducing substance undergoes oxidation because of the redox reaction's electron loss.

This problem is providing us with the number of moles of oxygen in a gas sample as 12.12 mol. Thus, the volume those moles occupy is required and found to be 271.5 L.

In chemistry, we study ideal gases under the assumption of no interactions among gas molecules, therefore the widely accepted equation, known as the ideal gas equation, we use to study the moles-pressure-temperature-volume relationship is:

[tex]PV=nRT[/tex]

Now, this problem gives n and asks for V at STP, which stands for standard temperature and pressure, taking the values of 273 K and 1 atm, respectively. Hence, we solve for the volume as follows:

[tex]V=\frac{nRT}{P}[/tex]

Thereafter, we plug in the numbers to obtain:

[tex]V=\frac{12.12mol*0.08206\frac{atm*L}{mol*K}*273K}{1atm}\\\\V=271.5L[/tex]

Answer:

Option A is the answer!

Explanation:

The photoelectric effect occur due to the release of electrons from atoms. Thus option A is correct.

The photoelectric effect is defined as a phenomenon in which electrically charged particles are released from or within a material when it absorb electromagnetic radiation.

It is also be defined as an emission of electrons when electromagnetic radiation hits the material.

It can be defined as a phenomena whereby light striking a metal surface causes electrons to be expelled from it.

The photoelectric effect is defined as a phenomena whereby electrons can be released from the surface of a metal when light shines on it.

Thus, the photoelectric effect occur due to the release of electrons from atoms. Thus option A is correct.

Boyle's law states the relationship between pressure and volume of a gas.

From Boyle's law, we know that volume and pressure of a given mass of gas are inversely proportional to each other. Hence, PV = k.

Now, in carrying out this experiment, the atmospheric pressure is assumed to be constant. If the atmospheric pressure changes during the experiment, here would have been a change in the measurements of balloon volume because air pressure changes would have interfered with the results.

Explanation:

We have that the  the pressure (in atm) of the gas at 50.0 °c is mathematically given as

P2= 2.17 atm

The Gay-Lussac's law states that pressure exerted by gas is directly proportional to the absolute temperature of the gas.

Generally the equation for the Gay-Lussac's law  is mathematically given a

P1 / T1 = P2 / T2

Therefore

T1 = 25C

T1= 25 + 273

T1= 298 K

And

T2 = 50C

T2= 50 + 273

T2= 323 K

Therefore

[tex]P2 = \frac{2.00 x 323}{298 }[/tex]

P2= 2.17 atm

Hence,  the pressure (in atm) of the gas at 50.0 °c is

[tex]P2 = \frac{2.00 x 323}{298 }[/tex]

P2= 2.17 atm
