Silver-109 has a mass of 109 amu. It is one of the isotopes of the silver atm.
<h3>What are isotopes?</h3>
The term isotopes has to do with the atoms of the same element that has the same atomic number but different mass numbers. This implies that the isotopes that we have do have the same number of protons but they do not have the same number of neutrons and the fact that they differ in the number of neutrons implies that would have the same chemical property.
We can see from the question that there are two isotopes of silver and tehse isotopes of silver have been identified as silver-107 and silver-109. The isotopes do have the same mass and not the same number of protons.
The percentage abundance of the two isotopes are not the same which means that one is more than the other. We can now see that the mass of the silver 109 in amu is 109 amu.

A galvanic cell is formed when two metals are immersed in solutions differing in concentration, when two different metals are immersed.
<h3><u>What is a </u><u>
Galvanic</u><u> </u><u>
cell</u><u> ?</u></h3>
- In order to provide a pathway for the flow of electrons along that wire, the galvanic cell makes use of the ability to split the flow of electrons during the oxidation and reduction processes.
- It forces a half-reaction and connects each to the other with a wire.
- A galvanic cell is an electrochemical device that converts chemical redox reaction energy into electrical energy.
- Electrically, it has a potential of 1.1 V. Oxidation takes place at the anode, which is a negative plate in galvanic cells. It is a positive plate where the reduction happens.
- An electrochemical device called a galvanic cell transforms chemical energy's free energy into electrical energy. A photogalvanic cell produces species that are photochemically reactive.

What is our main objective here??????????????????
Energy absorbed from
changing the phase of a substance from the liquid phase to gas phase can be
calculated by using the specific latent heat of vaporization. Calculation are
as follows:
<span> Energy = 1.35 mol CCl4 ( 153.81 g / 1 mol ) x 197.8 J/g </span>
<span>Energy = 41071.88 J</span>
