Answer:
A- Speed = distance/time
Explanation:
Would make sense and that's what I remember
Answer:
- <em>sp³ hydbridization</em> is the formation of 4 equal hybrid orbtials (same characteristcs) by the hybridization ("mixture") of two different kind of orbitals: 1 type s orbtial and 3 type p orbitals.
Explanation:
This hybridization is the result of the rearragement of the valence electrons that originally are in s and p orbitals, forming the new hybrid orbitals (sp³).
This is easily explained with carbon atom.
- Carbon has atomic number 6, hence it has 6 electrons.
- Thus, the electron configuration of carbon is: 1 s² 2s² 2p².
- So, there are four valence electrons that are in the 2s and 2p orbitals.
- The hybridization consists in that the four valence electons, instead of remain in two different energy levels (s and p) will form 4 orbitals, named sp³, each with the same energy.
- In summary the four electrons originally distributed as 2s² 2p² will be located as 2 sp³.
Mass of K = 39.1g/mole
Mass of H = 1g/mole
Mass of C = 12g/mole
Mass of O = 16g/mole
Mass of KHCO3 = 39.1 + 1 + 12 + 3*16 = 100,1g/mole
100% ------------ 100.1g of KHCO3
x% ----------------- 12g of C
x = 11,99% of C in KHCO3
100% -------------- 100.1 of KHCO3
y% --------------------3*16g of O
y = 47,95% of O in KHCO3
100% ------------- 100.1g of KHCO3
z% ---------------- 1g of H
z = 0,99% of H in KHCO3
11,99% + 47,95% + 0,99% = 60,93% ≈ 61%
<u>answer: C</u>
Orbitals or otherwise fully known as <u>Atomic orbitals</u> are regions of space around the nucleus of an atom. This is also where an electron believed to be found. The atomic orbitals allow atoms to make covalent bonds.
Hope I could help! :)
