The correction according to the Van Dee Walls equation is Vn-b
Answer:
The concentration of the solution is 1.068×10⁻⁴M
Explanation:
Hello,
To find the concentration of the solution, we'll have to use Beer-Lambert law which states absorption is directly proportional to the concentration of the solution.
Beer-Lambert law = A = εCL
A = absorption = 2 - log₁₀%T = 2 - log₁₀(34)
A = 2 - 1.5314 = 0.47
A = 0.47
ε = molar absorption coefficient = 4400
C = concentration of the solution
L = path length = 1cm
A = εcl
C = A / εl
C = 0.47 / 4400 × 1
C = 1.068×10⁻⁴M
The concentration of the solution is 1.068×10⁻⁴M
U can assume that riding the bus is a faster way to get to school because it is capable of a faster speed than a bicycle
The density of silver can be calculated by using the following formula:
Here, m is mass and V is volume.
To calculate density, mass of silver needs to be calculated first.
In FCC, the number of Ag atoms in a unit cell will be 4, atomic mass of Ag is 107.87 g/mol and number of atoms in 1 mol are 
atoms, thus, mass can be calculated as follows:
.
Now, volume can be calculated as follows:
First convert pm to cm:
Thus,
Putting the value to calculate volume,
Now, calculate density as follows:
Therefore, density of silver is 
.
Answer: 6. FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy.
7. TRUE. Solar energy is created when it is used in the process of photosynthesis in a plant. Then chemical energy is used when the plants create glucose.
I hope this help you out
