We will use this formula for first order:
㏑[A] = - Kt +Ao
when we have t (given)= 30 min = 30 x 60 = 1800 s (we here convert time from min to second.
then we assume that the initial concentration Ao = 1
and the concentration of A (final concentration = 0.25
So by substitution:
㏑(0.25) = - K * 1800 + ㏑(1)
1.39 = K * 1800
∴ K = 0.00077 s^-1 or 7.7 x 10^-4
Answer:
See below!
Explanation:
Chlorine is very electronegative, meaning that it will pull electrons, or negativity toward itself. When it pulls the negativity towards itself, the chlorine becomes partially negative and the carbon becomes partially positive. Because of this, the compound is polar.
Answer:
A solution of CH3Cl will not conduct electricity
Explanation:
Ionic substances conduct electricity because the solution is composed of ions. Ions are charge carriers in a solution. When an ionic substance is dissolved in water, the substance dissociates into its component ions. The concentration and activity of these ions determines the conductivity of the solution.
However, molecular substances are not composed of ions. Since they are not composed of ions, they do not dissolve in water to yield ions. This implies that solutions of molecular substances are do not conduct electricity.
CH3Cl is a molecular substance. It is not composed of ions, hence its solution does not conduct electricity.
Answer:
it's 5.93% but that's not an option so 6%
