Depending on the strictness of your teacher you can name it as either of the following:
2-methyl-propane or iso-propane
V₁=4.8 l
c₁=2.5 moles/l
c₀=6.0 moles/l
v₀-?
v(H₂O)-?
n(H₂SO₄)=v₁c₁=v₀c₀
v₀=v₁c₁/c₀
v₀=4.8·2.5/6=2.0 l
v(H₂O)=v₁-v₀
v(H₂O)=4,8-2.0=2.8 l
you need to take 2.0 liters of solution (6.0 M H₂SO₄) and 2.8 liters of water
Answer:
A. One unpaired electron
B. 5 unpaired electrons
Explanation:
In A ,Fe is in +3 oxidation state and Electronic configuration- [Ar]3d5
And NO2 is a strong field ligand hence it causes pairing in t2g orbitals and results one unpaired electron in dZX orbital.
In B, also Fe is in +3 oxidation state but F is weak field ligand hence causes no pairing of Electrons hence it results 5 unpaired electrons with electronic configuration t2g^3 eg^2
Answer: A.
Explanation:
Scientists disproved the theory of Spontaneous generation by creating experiments that showed living things cannot arise from nonliving material. An example of this is the flask experiment conducted by Louis Pasteur.
To find the number of neutrons in an atom you can use and equation
N = Mass no. - Protons
N of chlorine-36 = 36 - 17 = 19
so chlorine-36 has 19 neutrons
hope that helps
