Answer:
Yes
Explanation:
As long as its a solid, you can count it. It will be hard, but possible.
Answer:
The correct answer is 0.11 mol O₂
Explanation:
The chemical equation for the reaction of acetylene (C₂H₂) with O₂ to produce carbon dioxide (CO₂) and water (H₂O) is the following:
2 C₂H₂(g) + 5 O₂(g) → 4 CO₂(g) + 2 H₂O(g)
The chemical equation is balanced : with the proper estequiometrical coefficients. According to this, 2 moles of C₂H₂ reacts with 5 moles of O₂ to give 4 moles of CO₂ and 2 moles of H₂O.
In order to calculate how many moles of O₂ are needed to produce 0.085 moles of CO₂, we multiply the 0.085 moles of CO₂ by the factor 5 moles O₂/4 moles CO₂ (because 4 moles of CO₂ are produced by 5 moles of O₂ according to the chemical equation):
0.085 moles CO₂ x (5 moles O₂/4 moles CO₂) = 0.10625 moles O₂ = 0.11 moles O₂
The molar absorptivity is
Molar absorptivity is defined as the measure a compound's ability to absorb light of a specific wavelength. It is represented by the constant/symbol 'ε'.
The molar absorptivity is given by :
A = εcl
where A is the absorbance
ε is the molar absorptivity
c is the molar concentration of the compound
and l is the path length
here, the molar concentration of the solution is 0.16 mol
and the path length is 1 cm
to find the molar absorptivity , one must know the absorbance of the material.
