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.

By changing the number of protons in an element, you are fundamentally changing it to a different element.

It’s worth remembering that:

Protons identify the element

Electrons determine properties and behavior of the element

Neutrons contribute to isotopes and just help keep everything stable, by separating the charges. Remember opposites attract. Like charges repel.

An electric current of 1.00 ampere is passed through an aqueous solution of Ni(NO3)2. How long will it take to plate out exactly
Olegator [25]

Answer: It takes 193000 seconds to plate out exactly 1.00 mol of nickel metal, assuming 100 percent current efficiency.

Explanation:

1 electron carry charge=1.6\times 10^{-19}C

1 mole of electrons contain= electrons

Thus  1 mole of electrons carry charge=\frac{1.6\times 10^{-19}}{1}\times 6.023\times 10^{23}=96500C=1 Faraday

Ni(NO_3)_2\rightarrow Ni^{2+}+2NO_3^-

Ni^{2+}+2e^-\rightarrow Ni

96500\times 2=193000Coloumb of electricity deposits 1.00 mole of nickel

Q=I\times t

where Q= quantity of electricity in coloumbs  = 193000 C

I = current in amperes  = 1.00 A

t= time in seconds = ?

193000=1.00A\times t

t=193000s

Thus it takes 193000 seconds to plate out exactly 1.00 mol of nickel metal, assuming 100 percent current efficiency.
