Answer:
48.67 seconds
Explanation:
From;
1/[A] = kt + 1/[A]o
[A] = concentration at time t
t= time taken
k= rate constant
[A]o = initial concentration
Since [A] =[A]o - 0.75[A]o
[A] = 0.056 M - 0.042 M
[A] = 0.014 M
1/0.014 = (1.1t) + 1/0.056
71.4 - 17.86 = 1.1t
53.54 = 1.1t
t= 53.54/1.1
t= 48.67 seconds
Hence,it takes 48.67 seconds to decompose.
<h3>
Answer:</h3>
4551.37 Pascals
<h3>
Explanation:</h3>
The pressure refers to the force exerted by a substance per unit area.
The pressure is liquid is calculated by;
P = height × density × gravitational acceleration
In this case;
Height = 636.2 mm
Density = 0.7300 g/cm³
g = 9.8 N/kg
We need to convert mm to m and g/cm³ to kg/m³
Therefore;
Height = 636.2 mm ÷1000
= 0.6362 m
Density = 0.73 g/cm³ × 1000 kg/m³
= 730 kg/m³
Then, we can calculate the pressure;
Pressure = 0.6362 m × 730 kg/m³ × 9.8 N/kg
= 4551.3748 pascals
= 4551.37 Pascals
Therefore, the pressure of the column of decane is 4551.37 Pascals
