Answer:
after t = 3 hours compound A remain 0.396 M
t = 12.98 hours
Explanation:
P = P_0*e^(-kt)
t = 30 minutes = 30/60 hours = 0.5 hours
and P_0 = 0.60M
and P after t = 0.5 hours is 0.56 M
(0.56/0.6) = e^(-kt)
0.933 =e^(-kt)
k = 0.138
P = P_0*e^(-0.138t)
Now after t = 3 hours,
P = 0.6* e^((-0.138)*3) = 0.396 M
time when P = 0.1 M
0.1 = 0.6*e^(-0.138t)
t = 12.98 hours
My average speed for a walk depends on how far I walk.
If I walk one mile or more, then my average speed is about 2 miles per hour.

Although hand specimen identification is some what of an art; igneous rocks are classified using two critiria:
•Texture
•Chemical and mineral composition
Most of the time the rock name, such as basalt or granite, reflects the chemical composition. The minerals and textures are used as adjectives that modify the rock name. You might see a name like an olivine basalt or a quartz porphyry rhyolite.
As charge flows, the chemical energy of the battery is dissipated as the time of charge flow increases.
Electric power is defined as the rate at which electric energy is dissipated.
The power of the current flowing through the circuit is calculated as follows;
P = IV
P = I x IR
P = I²R
where;
- <em>P is the power dissipated</em>
- <em>I is the current flowing in the circuit</em>
- <em>R is the resistance of the circuit</em>
The electric energy is given as;
E = Pt
E = I²Rt
Thus, we can conclude that as charge flows, the chemical energy of the battery is dissipated as the time of charge flow increases.
