A solution of [FeSCN]^{2+} is found to have 37% transmittance at 447 nm. If the molar absorption coefficient (ε) is 4400 at λ_{max} 477 nm, what is the concentration of [FeSCN]^{2+} in the solution? (Assume the path length is 1 cm)

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

if you're asking what comes out, it's steam.

electron configurations. contents: quantum numbers and atomic orbitals 1. and the fourth (ms) specifies how many electrons can occupy that orbital. energy of the subshell; the energy of the subshell increases with l (s < p < d < f). thus the s subshell has only one orbital, the p subshell has three orbitals, and so on.
