Any substance that increases the concentration of 
in aqueous solutions is Arrhenius's acid.
<h3>What are Arrhenius acids?</h3>
Arrhenius define acids as substances with the chemical capacities to increase the concentration of hydrogen ion in aqueous solutions.
Thus, substances like HCl, HNO3, HBr, etc. would be considered an acid. This is because they ionize in aqueous solutions as follows:
HCl ---> +

Answer:
Explanation:
= Half-life of carbon = 5700 years
t = Time at which the remaining mass is to be found = 10400 years
= Initial mass of carbon = 11 g
Decay constant is given by
Amount of mass remaining is given by
The amount of the substance that remains after 10400 years is .
Hello!
You would expect to observe
2 triplets in the ¹H NMR spectra for o-chlorotoluene.
Multiplicity observed in ¹H NMR spectra when the atom couples with a neighbor ¹H atom. The multiplicity is equal to
N+1 where N is the number of neighbor atoms.
To observe a triplet, you'll need a molecule with 2 neighbor atoms. In o-chlorotoluene (shown in the figure), only protons C and D have 2 neighbor atoms (B and D; A and C, respectively), so you'll expect to see a 2 triplets.
Have a nice day!
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
