“If a certain metal is cooked, it will conduct electricity better”

- this is a hypothesis, since the statement is kind of vague...”certain metal”...and is written in an “if-then” format.

The amount of electric current that passes through a conductor is directly proportional to the voltage and is described as V = IR

- laws are usually scientific understanding that we’ve tested so much that we’ve come to a conclusion that can often be written out as a mathematical relationship. Hence, the “V = IR”

Electricity is the flow of electric charge in the form of electrons moving through a circuit

- this is a theory. I would give an explanation but I’m out of time.

Hope this helps

Approximately how many particles are in 2 moles?
schepotkina [342]

Answer:

1.2\times10^2^4 particles in 2 moles.

Explanation:

The number of particles that are contained in one mole, the international unit of amount of substance: by definition, exactly 6.022×10²³, and it is dimensionless. It is named after the scientist Amedeo Avogadro.

It is also known as Avogadro's constant.

∴ Number of particles in one mole = 6.022\times10^2^3

∴ Number of particles in 2 mole = 2 times Number of particles in one mole

∴ Number of particles in 2 mole=2\times6.022\times10^2^3=12.044\times10^2^3\approx1.2\times10^2^4

Hence there are 1.2\times10^2^4 particles in 2 moles.
