Answer:
The root mean squared velocity for CF2Cl2 is
Explanation:
From the question we are told that
The temperature is
Root Mean Square velocity is mathematically represented as
Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
Answer:
a) 2KOH + NiSO₄ → K₂SO₄ + Ni(OH)₂
b) Ni(OH)₂
c) KOH
d) 0.927 g
e) K⁺=0.067 M, SO₄²⁻=0.1 M, Ni²⁺=0.067 M
Explanation:
a) The equation is:
2KOH + NiSO₄ → K₂SO₄ + Ni(OH)₂ (1)
b) The precipitate formed is Ni(OH)₂
c) The limiting reactant is:
From equation (1) we have that 2 moles of KOH react with 1 mol of NiSO₄, so the number of moles of KOH is:
Hence, the limiting reactant is KOH.
d) The mass of the precipitate formed is:
e) The concentration of the SO₄²⁻, K⁺, and Ni²⁺ ions are:

Answer:
Correct option : "The mechanism results in a carbocation rearrangement in which a methyl shift occurs"
Explanation:
In the first step, 2,2-dimethyl-1-propanol gets protonated.
In the second step, a carbocationic intermediate is produced from removal of .
In the third step, shifting of methyl group occurs to produce more stable carbocationic intermediate.
In the fourth step, attacks the stable carbocation to produce 2-bromo-2-methylbutane.
So, correct option : "The mechanism results in a carbocation rearrangement in which a methyl shift occurs"
Full reaction mechanism has been shown below.
