Mass of Cl₂ : 164.01 g
<h3>Further explanation</h3>A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol Cl₂ :
mass Cl₂(MW=71 g/mol) :
Answer : The correct option is, electrons are not shared equally between atoms.
Explanation :
Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.
In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.
For example : is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.
Answer:
a) 79.66 seconds is the half-life of the reaction.
b) It will take seconds for 34% of a sample of an acetone to decompose.
c) It will take seconds for 89% of a sample of an acetone to decompose.
Explanation:
The decomposition of acetone follows first order kinetics
The rate constant of the reaction = k =
a)
Half life of the reaction =
For the first order kinetic half life is related to k by :
79.66 seconds is the half-life of the reaction.
b)
Let the initial concentration of acetone be =
Final concentration of acetone left after t time = [A]
For the first order kinetic :
Solving for t;
It will take 47.76 seconds for 34% of a sample of an acetone to decompose.
c)
Let the initial concentration of acetone be =
Final concentration of acetone left after t time = [A]
For the first order kinetic :
Solving for t;
It will take seconds for 89% of a sample of an acetone to decompose.
