The number of atoms : = 6.02.10²³
<h3>Further explanation</h3>
Given
mass = 20.17 g of Neon
Required
The number of atoms
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
mol Neon :
= mass : Ar Neon
= 20.17 : 20,1797 g/mol
= 0.999 ≈ 1
The number of atoms :
= 1 x 6.02.10²³
= 6.02.10²³
Shielding alpha and beta particles is part of radiation safety, which is followed very seriously in nuclear power plants, hospitals, laboratories where particle accelerators are used, and in many more situations. Alpha particles are much easier to block than beta particles. Alpha particles are positively charged helium nuclei, and beta particles are negatively charged electrons. Finding materials to block alpha and beta particles requires some serious consideration because of how dangerous radiation exposure is. Density is very important when is comes to blocking these particles. The cool thing about alpha particles, though, is how easily they can be blocked. You would think that blocking a particle would take some seriously thick metal or something, but you could actually use paper, or even plastic to block these particles!

<span>We are given with the equation that produces methane and water from the raection of hydrogen gas and carbon monoxide. This is expressed in the balanced equation: 3H2 + CO = CH4 + H2O. This is an exothermic process. The change that would shift the equilibrium to the right is </span><span>lowering the temperature of the reaction. </span>
Answer: C. Electrons are exchanged
Explanation:
Oxidation-Reduction reaction (Redox) is a type of chemical reaction in which there is a transfer of electrons between the reacting substance.
In this type of reaction, one of the reacting substance, called the Reducing Agent, undergoes Oxidation (loss of electrons), while the other reacting substance, called the Oxidising Agent ,undergoes Reduction (gains electron).
An emerald can be described as a precious gemstone that is commonly green. However, emeralds can be other colors. Emerald commonly describes a color, such as emerald green eyes.
