hybridization is defined as mixing up of the atomic orbital with nearly same energies according to linear combination of atomic orbitals. the orbitals formed are equal in energy and are called hybrid orbitals .
So my chem experiment asks us: What is the molarity of a 6.0 ppm solution (it's a 6.0 ppm chlorophyll solution, hexane is the so
2 answers:
Answer:
The first option is correct.
Explanation:
Concentration of chlorophyll is the ppm = 6.0 ppm
(1 ppm = 1 mg/kg)
6.0 ppm = 6.0 mg/kg
Mass of chlorophyll = 6.0 mg= 0.006 g (1 mg = 0.001 g)
Moles of chlorophyll =
volume of the solution = 1 L
Concentration(c) =
Where : n = moles of the compound
V = Volume of the solution
Concentration of the chlorophyll :

Answer: The time is 0.69/k seconds
Explanation:
The following integrated first order rate law
ln[SO₂Cl₂] - ln[SO₂Cl₂]₀ = - k×t
where
[SO₂Cl₂] concentration at time t,
[SO₂Cl₂]₀ initial concentration,
k rate constant
Therefore, the time elapsed after a certain concentration variation is given by:
We could assume that SO₂Cl₂ behaves as a ideal gas mixture so partial pressure is proportional to concentration:
In conclusion,
t = ln( p(SO₂Cl₂)₀/p(SO₂Cl₂) )/k
