Answer:
Helium and Neon have similar chemical properties because both of them completely fill the outer shell of their atoms' electrons, so there is nothing to share with other atoms, neither with the same element nor with any other element.
Explanation:
Helium and Neon are both noble gases . As elements react, their atoms, by losing, acquiring, or sharing electrons, complete their outer shells. Noble gas atoms already have full outer shells, so there is no tendency for them to lose, gain, or share electrons. There are incomplete outer shells of atoms of group 1 and 7 elements (so they are reactive)
<u>Chemical properties of HELIUM and NEON -:
</u>
- In group 8(or 0) of the periodic table, on the far right side, the Noble Gases are contained. Helium, neon, argon, krypton, xenon and radon are their names.
- They are extremely colourless and unreactive.
- They do not form bonds, so they still remain as single (monatomic) atoms.
- There is very little chemical reactivity in them.
Hence, helium and neon have similar chemical properties as they are the most stable due to having the maximum number of valence electrons their outer shell can hold.
Answer:
Percent yield of reaction is 75%.
Explanation:
Given data:
Moles of A = 2.0 mol
Moles of B = 4.0 mol
Moles of C formed = 1.8 mol
Percent yield of reaction = ?
Solution:
Chemical equation:
2A + 5B → 3C + D
We will compare the moles of A and B with C from balance chemical equation.
A : C
2 : 3
B : C
5 : 3
4 : 3/5×4 = 2.4 mol
Number of moles of C formed by 4 moles B are less thus B is limiting reactant and will limit the yield of C.
Percent yield:
Percent yield = actual yield /theoretical yield × 100
Percent yield = 1.8 mol / 2.4 × 100
Percent yield =75%
Answer:
true astroids are in space and are bigger than meteorites but smaller than planets, meteorites which are asteroids after landing on earth and losing most of its mass on its way
The base is the species that accept hydrogen, and the acids donate hydrogen ions. Dihydrogen phosphite acts as a base and hydrosulfide sulfanide act as an acid.
<h3>What are acids and bases?</h3>
Acids are molecules or chemical species that can donate a proton or a hydrogen ion to another chemical species.
Bases are the ions or molecules that accept a proton or hydrogen ion and release a hydroxide ion.
The acid and base relationship is shown as,
