Answer:
![t=147.24\ min](https://tex.z-dn.net/?f=t%3D147.24%5C%20min)
Explanation:
Given that:
Half life = 30 min
Where, k is rate constant
So,
The rate constant, k = 0.0231 min⁻¹
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k = 0.0231 min⁻¹
Initial concentration
= 7.50 mg
Final concentration
= 0.25 mg
Time = ?
Applying in the above equation, we get that:-
![t=147.24\ min](https://tex.z-dn.net/?f=t%3D147.24%5C%20min)
Its reversible, soluble, <span>mass, density, color, boiling point, temperature, and volume. </span>
Answer: heat
Other indicators: color change, odor, gas, temperature change.
Answer:
The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. ...
Boiling points increase as the number of carbons is increased.
Branching decreases boiling point.
