chegg 2. What pattern did you observe measuring cell voltages with a silver electrode versus with a platinum/H2 electrode There is a difference of -0.786 V in silver
<h3>What is cell voltages ?</h3>
The difference in electric potential between two points, also known as voltage, electric potential difference, electric pressure, or electric tension, is what determines how much labor is required to move a test charge between the two sites in a static electric field. Volt is the name of the derived unit for voltage (potential difference) in the International System of Units. Joules per coulomb, or 1 volt equals 1 joule (of work) for 1 coulomb, is how work per unit charge is stated in SI units (of charge). The quantum Hall and Josephson effect was first employed in the 1990s, and most recently (in 2019), fundamental physical constants have been added for the definition of all SI units and derived units. Power and current were used in the previous SI definition for volt.

Explanation:
Radioactive isotopes are unstable isotopes whose neutron/proton ratio differs from its stability ratio.
- These isotopes will naturally decay and break down on their own.
- A nucleus with neutron/proton ratio combination which is different different from its stability ratio will be unstable and split into one or more other nuclei.
- This is accompanied by the emission of small energetic particles.

Answer:
Phosphorus
Explanation:
Group V elements- Nitrogen, Phosphorous
period 3- Sodium, Magnesium, Aluminium, Silicon , Phosphorous, Sulphur, Chlorine and Argon
Group v and period 3 is phosphorus
The solid that comes out of a solution is called precipitate
Answer: 750ml
Explanation:
Using charle's law
V1/T1=V2/T2
V1= 500ml
T1= -73⁰C
V2= ?
T2=27⁰C
We can see that the temperature is in Celsius
Now,we will convert to Kelvin
Kelvin= 273+ Celsius
So convert the Celsius value to Kelvin
For T1= 273+(-73)
T1= 273-73
T1= 200K
For T2= 273+27
T2= 300K
V1/T1=V2/T2
500/200=V2/300
Cross multiply
200×V2=500×300
200V2= 150000
V2= 150000/200
V2= 750ml
So,
750ml of gas will occupy at 27⁰C
