Answer:
Explanation:
To find molecules, we will need to multiply the number of moles of carbon monoxide by Avogadro's number. Avogadro's number is .
So the equation would look like this:
Explanation:
Two different elements have similar chemical properties when they have the same number of valence electrons in there outermost energy level. Elements in the same column of the periodic table have similar chemical properties.
Answer:
The correct answer is b) 2
Explanation:
When is dissolved in water, silver acetate (AgCH₃COO) is dissociated into ions according to the following equilibrium:
AgCH₃COO ⇄ Ag⁺ + CH₃COO⁻
Where Ag⁺ is a silver cation and CH₃COO⁻ is the acetate anion (an organic anion). As we can see, from one single formula unit are obtained 2 ions (1 cation and 1 anion).
Therefore, the correct option is b) - 2
Quantum numbers are used to describe the location of electrons in atoms.
Principal quantum number(n) tells which energy shell the electrons reside in.
The first energy shell n = 1, second energy shell n = 2 and it goes on.
Azimuthal quantum number (l) states which orbital the electron is most likely to reside in. the number of orbitals in an energy shell depends on the principal quantum number. number of orbitals are from 0 to n-1
If l = 0, s orbital
l = 1 , p orbital
l = 2, d orbital
in 2nd energy shell the number of orbitals are 0,1 etc.
5s-
Principal quantum number n = 5
Azimuthal quantum number l = 0
6p
Principal quantum number n = 6
Azimuthal quantum number l = 1
4d
Principal quantum number n = 4
Azimuthal quantum number l = 2
H3C -- C -- CH2-- CH2-- CH2-- CH2-- CH2--CH3

CH2 -- CH3
Observe the longest chain. Then start counting from the branching side.
1 2 3 4 5 6 7 8
H3C -- C -- CH2-- CH2-- CH2-- CH2-- CH2--CH3

CH2 -- CH3
So there are 8 carbons in the long chain means Octane.
Now, there is a ethyl group at 2nd carbon.
So, it is 2-ethylocatane
2-ethylocatane
