You have to use Avogadro's number which is 6.02x10^23. The units of Avogadro's number is molecules/mole so you divide the number of molecules by Avogadro's number which will give you the number of moles.
(2.0x10^22 molecules)/(6.02x10^23 molecules/mole)=0.033 moles
B. Representative electrons
Firstly it is best to describe the shape and structure of an atom, an atom's system and structure is like of the solar planet, the heliocentric view where the sun is the neutrons and protons and the planets are the electrons. Moreover, the electrons are outside these neutrons and protons surrounding the entire system of its atomic structure. Its movement is like of a planet.
<span>An energy level also known as electron shell, or just shell is a location around an atom where electrons with a specific energy value, or quantum number may be found.</span>
The answer to this question is 192.5
Answer: transfer of heat by the actual movement of warmed matter
Explanation: convection is the process of heat transfer through fluids. When molecules absorbs heat they become excited and less dense causing it to rise.
Answer:
element
Explanation:
An element is a pure substance that cannot be separated into simpler substances by chemical or physical means. • There are about 117 elements.
