A solution was found to have a 15. 6 % transmittance at 500 nm, its wavelength of maximum absorption, using a cell with a path length of 5. 00 cm. Calculate the absorbance of the solution in a 1. 00 cm cell at 500 nm.
The correct answer is 0.161.
Solution:
Percentage transmission (%T) of the sample = 15.6
Therefore, Absorbance (A) 2 – log (%T) = 2 – log (15.6) = 0.8069
Use Beer’s law:
A = ε*c*l where ε = molar absorptivity of the solution, c = concentration of the solution, and l = path length of the solution.
Given A = 0.8069 and l = 5.00 cm, we must have
0.8069 = ε*c*(5.00 cm)
ε*c = 0.16138 cm-1
For the next part, assume that ε*c remains constant and we have
A’ = ε*c*l’ where l = 1.00 cm.
Plug in values and write
A’ = (0.16138 cm-1)*(1.00 cm) = 0.16138
Absorption measures the amount of light of a particular wavelength that a particular substance blocks from passing. The two main factors that affect absorption are substance concentration and optical path length. The net Absorption Rate is calculated using the formula of the total vacant area at the beginning of the period plus square feet.

The partial pressure of hydrogen gas in the vessel at the end is 12 atm
How do I determine the partial pressure of hydrogen gas?We'll begin by obtaing the new pressure of the vessel. This can be obtained as follow:
Initial pressure (P₁) = 10 atmInitial mole (n₁) = 2 + 3 = 5 molesNew mole (n₂) = 5 + 3 = 8 molesNew pressure (P₂) =?PV = nRT
Divide both sides by V
P = nRT / V
Divide both sides by n
P / n = RT / V
RT / V => Constant
P₁ / n₁ = P₂ / n₂
10 / 5 = P₂ / 8
2 = P₂ / 8
Cross multiply
P₂ = 2 × 8
P₂ = 16 atm
Thus, the new pressure is 16 atm
Next, we shall determine the mole fraction of hydrogen gas. This is shown below:
Mole of Helium = 2 moles Mole of hydrogen gas = 3 + 3 = 6 molesTotal mole = 2 + 6 = 8 molesMole fraction of hydrogen gas =?Mole fraction = Mole of element / total mole
Mole fraction of hydrogen gas = 6 / 18
Mole fraction of hydrogen gas = 0.75
Finally, we shall determine the partial pressure of the hydrogen gas. This can be obtained as follow:
Mole fraction of hydrogen gas = 0.75Total pressure = 16 atmPartial pressure of hydrogen gas =?Partial pressure = mole fraction of element × total pressure

Chlorine will combine with a non metal element carbon to form this molecular compound explain how these bonds are formed?
Answer: When carbon(C) combines with chlorine(Cl), carbon forms single covalent bond with each chlorine atom. The valence shell configuration of uncombined C atom is 2s2 2px1 2py1 .
During combination hybridisation takes place, an electron shifts from 2s to empty 2pz . These four orbitals merge to form four hybrid orbitals. Each hybrid orbital has 1 electron which pairs up with a valence electron of Cl atom to form a covalent bond. Thus the four hybrid orbitals form four single covalent bonds with four chlorine atoms. This completes each atom's octet and gives them noble gas configuration.
When two atoms of different elements combine they always have electronegativity(EN) difference due to which the shared pair of electrons is more closer to more electronegative atom. This gives the bonds some ionic character. So no bond between two atoms of different elements can be purely covalent.
Explanation:
Does an increase in the number of electrons around the nucleus of an atom always increase the size of the atom?
Answer: The radius of atoms increases as you move down a particular group in the periodic table of elements because an atom grows larger as the number of electronic shells increases.

Bomb calorimetry is best for determining heat values. Because we cannot have a bomb calorimeter for every pair of students, we use what is readily avaliable. Why would two styrofoam cups be an economical way of determining these heat values and what is the of the major pitfalls of using this system?.
Styrofoam cups have more capacity to absorb heat in higher rate and it is economically cheap. However, it never reaches the reaction's full temperature before you stop taking readings.
What is bomb calorimeter?A bomb calorimeter is used to determine the heat energy absorbed or released in a reaction.The reaction mixture and the calorimeter both heat up.
Since more of the reaction's heat was used to warm the calorimeter than the reaction mixture, a calorimeter that absorbs a lot of energy will have a significantly lower final temperature.
The calorimeter constant is a quantity that depends on the composition and mass of the calorimeter. Steel and styrofoam both absorb heat at a higher rate per gram, although the steel calorimeter is likely heavier.
